Renewable Energy Sources Explained

Renewable Energy Tax Credits reduce project CAPEX via ITC/PTC incentives for solar, wind, battery storage, and EV charging, supporting grid modernization, power electronics, and IEEE-compliant interconnections while accelerating decarbonization and load flexibility.

What Are Renewable Energy Tax Credits?

ITC/PTC credits cut capex for electrical systems—solar PV, wind, storage, EV chargers—boosting ROI and grid reliability.

✅ Offsets inverter, transformer, and protection system costs

✅ Applies to solar, wind, storage, microgrids, and EVSE

✅ Encourages IEEE 1547 interconnects and smart inverters

The Government of Canada wants Canadians to invest in a healthier environment, a more stable energy future and a more competitive economy, so it offers innovative Renewable Energy Tax Credits. For an overview of complementary programs, the resource at alternative energy incentives outlines how federal and provincial measures align with investment goals today.

In order to achieve these goals, two specific Renewable Energy Tax Credit measures are available to encourage investments in energy efficiency and renewable energy projects:

• Class 43.1 in Schedule II of the Income Tax Act allows taxpayers an accelerated Renewable Energy Tax Credit write-off of certain equipment that is designed to produce energy in a more efficient way or to produce energy from alternative renewable energy sources.

• Canadian Renewable and Conservation Expenses (CRCE) is a category of fully deductible expenditures associated with the start-up of renewable energy and energy conservation projects for which at least 50 per cent of the capital costs of the property would be described in Class 43.1.

Investors can also consult alternative energy tax credits to understand how project structures interact with other deductions and incentives available in Canada.

Investments in energy efficiency and renewable energy are helping to reduce Canada’s consumption of fossil fuels and minimize the production of greenhouse gases that contribute to climate change and other environmental problems. These investments also contribute to the development of new technologies1 and lead to export opportunities. It’s all part of the government’s ongoing efforts to promote sustainable development by integrating economic and environmental goals. Further context on market benefits is provided in clean renewable energy discussions that track growth trends and policy impacts across sectors worldwide.

Sustainable development will ensure the continued prosperity of Canadians while safeguarding our natural heritage for future generations. As deployment expands, insights into renewable power generation can help stakeholders benchmark performance and grid integration approaches in comparable jurisdictions.

Canadian Renewable Energy Tax Credits and Conservation Expenses

The early development phase of renewable energy and energy conservation projects typically involves certain intangible costs, such as feasibility and resource assessment studies. The CRCE category of expenditures was introduced in the 1996 Budget to allow investors Renewable Energy Tax Credits to fully write-off certain intangible costs associated with investments in renewable energy and energy conservation projects. CRCE is intended to promote the development of conservation and renewable energy projects in the same way that is currently done for investments in other types of resource activities.

Under CRCE, Renewable Energy Tax Credits allow eligible expenditures are 100 per cent deductible in the year they are incurred or can be carried forward indefinitely for deduction in later years. These expenditures can also be renounced to shareholders through a flow-through share agreement, providing the agreement was entered into before the expense was incurred. To be eligible, costs must be incurred after December 5, 1996. For the legislative basis of flow-through shares and CRCE expenditures, please refer to Sections 66 and 66.1 of the Income Tax Act and to Section 1219 of the Income Tax Regulations.

In parallel, understanding how markets value renewable energy credits can enhance financial models where environmental attributes are monetized alongside tax deductions.

Class 43.1 Accelerated Capital Cost Allowance

Class 43.1 provides an accelerated rate of write-off for certain capital expenditures on equipment that is designed to produce energy in a more efficient way or to produce energy from alternative renewable sources.

Class 43.1 allows taxpayers to deduct the cost of eligible equipment at up to 30 per cent per year, on a declining balance basis. Without this accelerated Renewable Energy Tax Credit write-off, many of these assets would be depreciated at annual rates of 4, or 20 percent (with the exception of expenses eligible for the pre-existing Class 34, which were deductible at an annual rate of up to 50 percent). In planning capital acquisitions, awareness of broader trends in alternative energy development can inform equipment selection and timing for making claims under this class.

What Types of Systems Qualify?

In general, the following types of systems qualify for CRCE Renewable Energy Tax Credit or Class 43.1 write-off:

Electricity Generation Systems

• certain cogeneration and specified-waste fuelled2 electrical generation systems
• small-scale hydro-electric installations (not exceeding 15 megawatts of average annual capacity)
• wind energy electrical generation systems
• enhanced combined cycle systems
• expansion engines
• photovoltaic electrical generation systems (three kilowatts capacity or larger)

Specified-waste fuels, both for electricity generation and heat production, are defined as municipal waste, wood waste, landfill gas or digester gas.

• geo-thermal electrical generation systems
• electrical generating systems using solution gas that would otherwise be flared during the production of crude oil

Thermal Energy Systems

• active solar systems (including groundsource heat pumps)
• heat recovery systems
• specified-waste fuelled heat production equipment

Note: Thermal energy systems qualify only if their primary purpose is to produce thermal energy for use directly in an industrial process.

Eligible Expenses
Intangible expenses eligible under CRCE Renewable Energy Tax Credits include:

Test Wind Turbines

Costs related to the acquisition and installation of a test wind turbine – defined as “the first wind turbine installed at the site of a proposed wind farm, whose primary purpose is to test the energy production at the site” – are included in the CRCE category of expenses. In order to be eligible, a favourable prior opinion must be issued by the Minister of Natural Resources Canada for each installation.

Tax Incentives
The following types of costs are eligible for an accelerated rate under Class 43.1:

• machinery and equipment
• related soft costs for design, engineering and commissioning
• other services required to make the system operational

Many proponents also leverage alternative energy grants to complement accelerated allowances and reduce upfront cash requirements for project execution.

Depending on all the facts of a particular situation, the cost of modifications and improvements to existing qualifying equipment may also be eligible, provided that:

• the costs increase the capacity or performance of the equipment
• the resulting system continues to meet the conditions for qualification

The following are generally ineligible under Class 43.1:

• operating costs

Renewable energy systems integrate solar PV, wind turbines, battery storage, inverters, and smart grid controls for efficient generation, power conversion, and grid integration, enabling resilient microgrids and low-carbon, distributed electricity.

What Are Renewable Energy Systems?

Networks that convert renewable sources to grid-quality power using power electronics, storage, and control systems.

✅ Power electronics: inverters, converters, MPPT for PV and wind

✅ Grid integration: protection, synchronization, and power quality

✅ Energy storage: batteries, EMS, frequency and voltage support

Renewable energy systems today can be a cost effective alternative for areas with high electricity connection fees. For an overview of how stand-alone configurations work in remote areas, see this guide to off-grid solar power systems and typical cost considerations.

It is also possible to connect renewable energy power systems to the grid, reducing the amount of electricity you need to purchase, or in some cases, allowing you to export surplus power into the grid. Many homeowners start with a basic solar PV system to offset daytime loads before expanding capacity.

About renewable energy systems

Renewable energy is energy produced from sources which can be replenished or replaced from natural sources. For a deeper introduction, explore this overview of renewable energy and common technologies.

The most common forms of renewable energy used include:

• photovoltaic modules;
• wind turbine generators; and
• micro hydro generators.

Homes usually are serviced with electricity from any of these renewable energy systems on their own or in combination with other electric power systems. Resources on broader renewable alternative energy can help you compare options for your site.

Grid-interactive vs. stand-alone power supplies

Since renewable energy systems are often intermittent, (because solar panels only operate during daylight and mostly sunny days) a method of storing the electricity is required. The most common solution for this situation is to incorporate the use of storage batteries. Power from the solar array is used to charge batteries for use later in the day. Because these systems work independently from the electricity grid, they are often referred to as "stand alone power systems". In situations where the cost of connection to the power grid is prohibitive, a stand-alone renewable energy system can be cost effective. Many stand-alone systems use diesel or gasoline generators to recharge batteries during extended period without solar energy.

When planning capacity, it's helpful to weigh the pros and cons of solar power for your climate and usage profile.

An alternative is to use the electricity grid to store the energy. These systems are known as grid-interactive systems. The renewable energy is converted to electricity for use in the household and any surplus power is fed into the grid. Power is drawn from the grid when the renewable energy system is not enough to meet the home's energy demand. Some electric utilities prefer that all of the power from the solar power system is sent directly to the grid and metered separately , which means that all the electricity to the home comes from the grid as it is with conventional homes.

Components and features of stand-alone renewable energy systems.

Renewable energy systems consist of several very basic component equipment parts and there are key features which are briefly described and shown on this page.

1. Electric Power Generating Equipment
2. PV modules, wind turbines, micro-hydro generators, or a petrol or diesel generator can provide electric power production on their own or in concert with other systems.
3. Control and regulation equipment
4. Various types of power regulators, controllers, power meters and power circuit breakers may be used to control battery charging and to provide power protection.
5. Energy storage
6. Specialized large capacity batteries are usually used to store otherwise lost energy so that a reliable source of power can be available when needed.
7. Inverters
8. These devices convert electricity from the batteries or renewable energy source to the electricity used by household appliances (240 V AC).
9. Specialized “grid-interactive” inverters are able to feed electricity produced by renewable sources into the electricity grid without disruption to the household electricity supply.
10. Control Box
11. Wiring and electrical accessories

Well-designed renewable energy systems should include special wiring that is capable of keeping energy losses to an absolute minimum. Adequate power fusing, electrical grounding, lightning protection and other measures should be used in the renewable energy system.

• Home design, lighting and various appliances

   

  TNew home designs should incorporate useful energy efficiency features. Also, high efficienct lighting systems and appliances can be selected and specified to keep the energy load to a bare minimum, thus aiding to reduce the cost of such systems.

  Grid-interactive renewable energy power systems

  In addition to stand-alone systems, which require batteries to store energy, REPS can operate in conjunction with the mains electricity system. These are known as grid-interactive or grid-connected systems.

  How do they work?

  In grid-interactive renewable energy systems electricity is still generated from a renewable energy source in the same way as a stand-alone system. The electricity generated then passes through a specially approved power inverter, which converts electric energy into conventional 240 V which in turn is used by home appliances. When there is surplus electricity generated, it will be sent back through the inverter into the power grid. If the home consumes more electricity than your renewable energy system is producing, the power provider automatically will supply the balance of the energy required without any disruption to home appliances. Selecting a certified solar power inverter ensures grid compliance and optimal performance.

  Your power meter measures the level of outgoing and incoming electricity. This provides a net usage amount for your house. In the majority of cases, surplus electricity which is fed back to the electric utility is credited back to you. The net amount that is actual consumption is charged for that billing period. In reality, your power meter can become a cash register. Specialized "smart" meters are sometimes used where more detailed power monitoring is required. As there are variations to this process, check with your electricity supplier for more information on equipment and metering details for your property.

  What are the benefits?

  The major benefit of grid-interactive renewable energy systems is that they produce power from clean, renewable solar energy, allowing householders to reduce greenhouse gas emissions and improve our environment. As renewable energy systems use the main electricity grid as a back-up, power is always available and systems can be sized according to the customer’s requirements and budget. For background on technologies and policy, review renewable energy facts for informed decision-making.

Renewable power generation harnesses solar PV, wind turbines, and hydroelectric resources, using inverters, MPPT, and energy storage for grid integration, power quality, reliability, and decarbonization across smart grids and distributed generation.

What Is Renewable Power Generation?

Electrical generation from wind, solar, and hydro via grid-tied systems, inverters, and storage to cut emissions.

✅ Includes solar PV, wind turbines, and hydroelectric plants

✅ Employs inverters, MPPT, and converters for power quality

✅ Integrates storage, microgrids, and smart grid control

Renewable power generation is one of the most important subjects in today's electricity production industy and in the future will dominate the agenda to remove power generation from the use of fossil fuels As priorities shift, a clearer understanding of renewable energy sources helps frame policy and investment decisions.

Of all the energy currently consumed in Canada, about 3,700 PJ (46%) is used to generate electricity. Canada has approximately 112 GW of installed electricity generation capacity, and produces approximately 561,805 GWh of electricity annually11 , resulting in a $27 B/yr business12 . Most electricity generation, transmission and distribution have traditionally been handled by vertically integrated provincial monopolies. This resulted in the construction of large-scale centralized power generation facilities and massive transmission systems owned by the same generator. The market is currently evolving under new deregulation guidelines. These shifts are framed by national discussions on renewable electricity policy and markets that influence provincial planning across Canada.

There are currently five main sources of power generation in Canada: natural gas, oil, coal, hydro (larger systems), and nuclear. The smallest component is from "other" sources (<2%), which includes renewable power generation. The National Energy Board estimates that "other" renewable power generation sources will reach 5.5 GW of installed capacity under the Business As Usual scenario, or 16.1 GW under the Techno-Vert scenario13, by the year 2025.Projection figures vary considerably throughout the industry and among government departments and jurisdictions,but are sufficient to provide a range from which to make some reasonable assessments. Contextualizing these categories against the spectrum of renewable power sources clarifies where incremental capacity is most likely to emerge.

Renewable Power Generation

Building on this theme, many jurisdictions measure progress by how much renewable power can reliably contribute during peak demand conditions.

Each sub-sector is examined for its potential to produce electricity and displace conventional fossil fuel electricity generation. Some of the fuels may have other - or even better - applications involving renewable power generation. Cross-sector comparisons with broader renewable alternative energy pathways can highlight complementary uses and integration strategies.

• Wind generated electricity
• Solar energy converted into electricity
• Stationary Fuel Cell technology that generates electric power
• Electric power generated from bio energy sources

• Wind Power: Wind power is becoming the leading non hydro-electric renewable energy source of North American electricity generation. The wind power industry, like the larger renewable power generation industry, has benefited from many years of public and private investment and technology improvements from countries around the world. As a result,some wind installations in Canada are now cost-competitive with (and even less expensive than) conventional electricity generation-even without the Wind Power Purchase Incentive (WPPI) program. Because there is lots of rural property in with suitable wind potential, it means there are many suitable locations which can support renewable power generation. The current focus of the wind power industry is to erect wind turbines and make them operational in time to meet future electricity demand.

• Solar PV Power: Solar energy is traditionally classified in three ways:Photovoltaics (solar electricity,or PV),Solar Thermal (heat) and Passive Solar (displacing the need for active heating or cooling). Most residential, commercial and industrial buildings require both electricity and heat (hot water,space heat,etc.). At this time,this report only focuses on Solar PV. If required,a full treatment of solar thermal (or the combined use of PV and solar thermal) may be conducted in a future analysis.
• Bio-electricity Power: Biofuels encompass all forms of renewable energy derived from bio-based matreials. Ttwo of the four types of renewable power generation from bioenergy sources are bio oil and bio gas. Bio oil can also be converted to electric power in means other than boiler combustion. Generally, bio-renewable power generation involves feedstock collection, fuel production and electricity generation.
• Stationary Fuel Cell Power (Hydrogen): Hydrogen as a possible renewable power generation source opens up a broad application area from alternative energy fuels in transportation to renewable power generation using special hydrogen fuel cells.While the application area for hydrogen is large,the specific focus of this report is on the use of hydrogen fuel cells for the delivery of renewable power generation to electricity grids.

Solid Biomass combustion is the most prominent form of biomass use in Canada. Biomass co-generation is already used widely in the pulp and paper industry for power, space and process heating. It is an established technology which needs improvement, but has not been a strong focus of biotechnology research and development. Advances in controls and co-firing are improving the competitiveness of biomass within the wider alternative energy power landscape for industrial sites.

The top five near-term investment opportunities for renewable power generation include:

Targeted pilots and standards can accelerate alternative energy development while de-risking capital for utilities and independent producers.

• Expanded Feedstock for Bio-electricity - To be successful, electrical generation (fuel conversion) equipment must be able to use a wider range of biomass feedstocks beyond the high quality sources that are currently used. Further, new logistics (collection, harvesting, refining) and conversion processes must be developed to supply a steady and reliable source of these additional raw materials for the emerging biofuel processes and bio-electricity facilities. Examples include technologies that go beyond corn-based ethanol8 and white-wood based pyrolysis.
• Wind Power Grid Integration Hardware - Connecting wind farms to the grid in a standardized,cost effective, and reliable way involves both new technology solutions and policy development. While grid connection is largely a policy issue, there are emerging technologies that can increase wind system power quality and reliability, which will help them gain acceptance among utilities.
• Liquid Biomass ( "Bio Oil") Plant Scale-Up - Demonstrations are required to validate the technical and economic viability of bio-processing plants as they scale from prototype to commercial sizes: ie: wood pyrolysis has progressed to the point of full production and needs to prove its value based on the many products that are derived.
• Large Wind Turbine Component - The wind power industry requires larger wind turbines to achieve energy economies of scale. However, to remain competitive in the renewable power generation business, certain ways must be explored to decrease the weight/power output ratio of wind turbines while at the same time increasing equipment life. It is being learned that new investments are required in the research and development of lighter, stronger and more cost-effective wind turbine components and tower designs.
• Solar PV Building Integration - Similar to wind, solar PV systems in Canada require greater access to the power grid.In the residential, commercial and industrial building markets there is the technical potential to fully integrate solar components within the structure and have it replace and reduce power demand from current sources. The cost of the solar power systems and their integration into renewable power development needs to be addressed. Many technological solutions and new energy policies may be required.

Renewable energy projects optimize power systems with grid integration, solar PV, wind turbines, battery storage, inverters, and power electronics, enhancing smart grid reliability, microgrids, transmission, and distribution through modeling, protection, and control engineering.

What Are Renewable Energy Projects?

Projects that design, integrate, and control solar, wind, and storage for reliable, efficient electric power systems.

✅ Grid integration studies: load flow, stability, and protection schemes.

✅ Power electronics and inverter control for MPPT and grid codes.

✅ SCADA, forecasting, and storage optimization in microgrids.

Renewable Energy Projects seem to have survived the first cycle of the world economic recession. In fact, late 2008 and all of 2009 seemed better than many economists had recently expected. After a slowdown in world investment activity at the end of 2008, sustainable energy projects enjoyed a rebound during the final three quarters of 2010. For readers seeking a concise overview, the concept of what renewable energy is underpins these investment trends today.

The result was total new investment in worldwide Renewable Energy Projects reached about $162 billion in 2009, down slightly from the revised target of $173 billion for 2008. This was still the second highest annual figure ever recorded and nearly four times the total investment level of 2004. This performance demonstrated that Renewable Energy Projects were certainly not a typical bubble created by the so-called "credit boom", but was rather an investment story that will continue to be important for years to come. Understanding the mix of renewable energy sources helps explain the durability of capital flows in this sector.

The visual underscores how renewable power markets can rebound quickly when financing conditions stabilize.

While many policy-makers have increased their focus on encouraging the growth of Renewable Energy Projects, (partly to stimulate job creation and and offset the forces of recession) projects received new support. From the financial crisis of autumn 2008 until the spring of 2010, the world's chief economies set aside about $188 billion of “green stimulus” programs for Renewable Energy Projects. And since that time, the money has started to be spent. The United States recently announced a large grant scheme to assist the financing of renewable energy projects, and other countries followed the example of Germany, Spain and other European countries by commencing feed-in tariff programs to encourage and stimulate investment in Renewable Energy Projects.. Such measures are pivotal as governments scale clean renewable energy deployment across sectors and regions worldwide.

The major development banks, led by Germany’s KfW and the European Investment Bank, also became important actors in helping Renewable Energy Projects to weather the storm and expand into new markets. However, Renewable Energy Projects have often to cope with a bumpy path.

Blended finance vehicles increasingly target diverse renewable power sources to spread risk and accelerate grid integration across emerging markets.

The story of 2009, however, was one of resilience for Renewable Energy Projects. While there were areas of weakness such as project development in the US and finance for biofuel plants, there was also a decisive shift in the balance of investment towards developing countries and particularly China. Renewable Energy Projects in China was the strongest feature of the year by far, although there were other areas of strength in the world in 2009 such as offshore wind investment in the North Sea and the financing of power storage and electric vehicle technology companies. There was also a marked improvement in the cost competitiveness of renewable power generation compared to fossil-fuel electricity generation. These shifts align with fundamentals described in renewable energy facts that clarify cost trends and technology learning curves.

New investment in Renewable Energy Projects in 2009 was $162 billion, down from a revised $173 billion in 2008. The 7% fall reflected the impact of the recession on investment in Europe and North America in particular, with renewable energy projects and companies finding it harder to access finance:

• China saw a surge in investment in Renewable Energy Projects. Out of $119 billion invested worldwide by the financial sector in clean energy companies and utility-scale projects, $33.7 billion took place in China, up 53% on 2008. Financial investment in Europe was down 10% at $43.7 billion, while that in Asia and Oceania, at $40.8 billion, exceeded that in the Americas, at $32.3 billion, for the first time.
• Clean energy share prices rose almost 40% in 2009, reversing around a third of the losses they experienced in 2008. The WilderHill New Energy Global Innovation Index, or NEX, which tracks the performance of 88 sustainable energy stocks worldwide nearly doubled to 248.68 from its low of 132.03 reached on 9 March 2009.
• Major economies began to spend some of the estimated $188 billion in Renewable Energy Projects they announced in the months after the collapse of Lehman Brothers in September 2008. However the wheels of administration take time to turn, and even at the end of 2009, only some 9% of the money had been spent. Larger proportions of the stimulus funds are likely to be spent in 2010 and 2011.
• Total investment in Renewable Energy Projects by venture capital funds was $2.7 billion in 2009, down 36% on 2008. VC players found it harder to raise new money, because of general investor caution and because exits were hard to achieve given the weakness of stock markets.

Amid these fluctuations, the long-term outlook for renewable electricity remains strong given policy support and improving economics.

Renewable power sources deliver clean energy via solar PV, wind turbines, hydroelectric, geothermal, and biomass, enabling grid integration, power electronics, smart inverters, and energy storage for efficient, low-carbon electricity generation and resilient distribution.

What Are Renewable Power Sources?

Systems that convert solar, wind, hydro, and biomass into electricity via inverters, power electronics, and grid ties.

✅ Power electronics: MPPT, converters, and smart inverters for PV and wind.

✅ Grid integration: protection, frequency/voltage control, and stability.

✅ Energy storage: batteries, supercapacitors, and power quality management.

Renewable Power Sources involve a wide range of modern technologies that do not rely on fossil fuels or non-renewable energy sources to generate electricity

For a broader overview of policies, technologies, and market adoption, the field of renewable power continues to evolve rapidly worldwide.

The following technology risks have been identified for various renewable power sources. The descriptions are based on the outputs from the Needs Assessment, and the results of the Technology, Market and Sustainability analyses.

Understanding these risks also requires situating each technology within the wider ecosystem of renewable energy sources that shape supply, demand, and policy trajectories.

• Wind Power: Wind turbine power generation is a well-developed technology, especially in the medium/large-sized range. Small units of less than 100 kW to very large units of more than 2MW require further technological research and development. Wind turbine technology is generally finding its most effective application in large scale wind farms with turbines greater than 2MW and whcih are grid-connected.

Grid integration and ancillary services markets are central to scaling wind, as demonstrated by best practices in delivering reliable renewable electricity across diverse regions.

As wind technologies near full market commercialization,the financial and market risks become more important. Specifically,the price point for the produced power, as well as the regulatory acceptance (through appropriate codes and standards) is the key issue. Capital costs are high ($1200-$1500/kW) relative to conventional electricity generation,which are <$1000/kW. Those technologies which help address the cost-competitiveness will be of interest. Comparative analyses of learning curves and procurement models show how renewable power generation can achieve competitive levelized costs under supportive frameworks.

In general, wind power is considered a medium-to-low risk proposition, compared to the other technologies being considered. Given the substantial amount of Canada's energy needs that can be met by wind on our current electrical grid without a major technical challenge, SDTC's wind investment efforts are likely to be weighted towards large-scale technologies. This does not preclude investments in small-scale, non-grid-connected systems, but the net environmental and economic impact would need to be considered.

These considerations also inform deployment pathways alongside microgrids and storage in remote provinces, where flexible alternative energy power solutions can complement existing infrastructure.

• Solar PV Power: Solar panel development has become quite refined, so the current challenge is to improve the production techniques of the panels in order to reduce overall costs,and the environmental impacts of production. Investments in improved production technologies may still be considered a high risk proposition because few such technologies have so far been identified. In terms of the market, there is fairly wide acceptance of solar technologies, but application is fragmented (residential and remote users), and there is little acceptance and integration on a grid scale. Solar systems are harder to justify economically as major generation sources, so many are being used in individual residential and small commercial applications. Consequently,there are growing aesthetic issues (solar panels on roofs and lawns are facing the same issues that large satellite dishes once had).

Manufacturing innovation and policy incentives continue to shape alternative energy development for PV, influencing supply chains, permitting, and workforce training.

Solar power is not a stand-alone solution for large-scale electricity generation:it requires a form of energy storage or baseload generation. However, in certain niche applications, solar power is quite acceptable. Such solar power applications are likely to have the greatest environmental and economic benefits in the short term. Over the longer term, when time-of-day rates are implemented, peak-shaving applications will become more attractive. Canada should be seeding early applications that demonstrate the benefits of peak-shaving in various classes and installation locations.

On balance, the high financial and market risks result in an overall high risk rating for solar PV for the generation of grid-scale power.

• Bio-electricity Power: Bio oil and Bio gas technologies are well into the development cycle,but there are only a few major players at this point.Financially,the technology has not yet been proven as a primary power generation source. However,the value proposition shows good potential if the co-products of the technology (heat and downstream bio products) are factored into the financial equation. While there is no evidence of an integrated market infrastructure at this point,the costs and complexities of creating such infrastructure are not considered to be as high as for other forms of renewable energy. This is largely because such systems could be considered as a means to improve efficiency in the agricultural and waste management areas (bio gas) and offer an attractive alternative for power generation in remote communities.

When aligned with waste valorization and district heating, integrated projects contribute meaningfully to renewable alternative energy outcomes that strengthen both resilience and community benefits.

• Stationary Fuel Cell Power (Hydrogen): Fuels cells still face very high developmental risk as a source of electricity generation (the world's largest installed pilot project of 250 MW is experiencing ongoing technical problems. Material costs are still very high (owing largely to the rare earth materials-mainly platinum-required to make them work), and the market infrastructure is still considered to be in its infancy. This results in an overall high risk rating for power stationary fuel cells that are going to be connected to the power grid. Less expensive hydrogen fuel supply and greater market availability are expected in the future.

Renewable power drives grid decarbonization via solar PV, wind turbines, hydropower, energy storage, power electronics, and smart grid integration, optimizing reliability, efficiency, and demand response in modern electric power systems.

What Is Renewable Power?

Renewable power is electricity from sustainable sources, using power electronics and storage for grid integration.

✅ Power electronics: inverters, converters, MPPT control

✅ Grid integration: protection, stability, frequency regulation

✅ Energy storage: batteries, BMS, dispatch for peak shaving

Renewable power technology is developing rapidly around the world aided by range of economic support mechanisms. This paper reviews the various mechanisms, and explores the relative merits of technology push and market pull approaches. It compares the approaches adopted in the UK with those used elsewhere. For readers new to the topic, a clear overview of what is renewable energy helps frame the policy context being discussed here.

THE RENEWABLE CHALLENGE
Renewable power technologies are new entrants into the world's electricity generation systems. However, they face an uphill struggle against the well established dominant electricity generation power technologies coal and gas, plus nuclear. Given increasing concerns about climate change, governments around the world have tried to simulate the expansion of renewable power generation via a range of subsidies and other financial support systems. As policymakers weigh options, comparative lists of renewable energy sources illustrate how technology maturity and costs vary across the sector.

Underlying the approaches to the development of renewable power technologies that have been adopted around the world is a basic distinction between supply side "technology push" approaches and demand side "market pull" approaches. It was perhaps inevitable that technology push dominated initially, in the mid 1970s, as new technologies needed research and development (R&D) effort, with much of the funding coming from government in the form of grants to research teams. However, by the early 1980s, the emphasis shifted in most countries to a market pull approach. Evidence from markets that track renewable power sources shows how pull mechanisms can accelerate deployment once early R&D has de-risked the technologies.

MARKETS OR SUBSIDIES?
Renewable power technologies need subsidies to get established, but at some point they should be able to compete with traditional methods of generating electricity, without subsidy. Wind power has nearly reached that point, and some waste or biofuel combustion options have already passed it. So, for these attractive renewable power technologies, the energy market has achieved its primary goal, even though it has maybe not led to much overall installed capacity. In practice, sustained cost declines have followed broader adoption of clean renewable energy solutions in competitive procurement schemes.

However, there are new renewable power options which need continued support, such as wave and tidal power. With the large scale wave and tidal programs abandoned, and in the new liberalized electricity market, the emphasis being on smaller scale plants, the focus amongst the surviving research teams had been on smaller scale inshore and onshore wave system and on the more recent idea of extracting renewable power from tidal flows.>/p>

For emerging marine concepts, insights into alternative energy power provide useful parallels for scaling prototypes to commercial arrays.

Projects like this, which were at best at the demonstration stage and more usually at the R&D stage, are not suited to support under the NFFO or the RO, which are meant for 'near market' technologies. By contrast the REFIT approach has provided support for technologies such as photovoltaic solar which are still very expensive on the assumption that costs will come down later as the market for the technology was expanded by subsidised lift off. So far, as we have seen, the UK approach does not seem to have done enough to help much near market technology take off. It is even less suited to less developed technologies. This may be one reason why, despite having a very large renewable power potential, so much of the world lags behind North America in terms both of developing capacity now, and in terms of meeting targets for the future. International case studies of alternative energy solutions underline the importance of stable, long-term policy design for investor confidence.

The challenge facing the United States is particularly striking. Whereas Germany already gets 14 per cent of its electricity from renewable power sources, the United States gets only about 1 per cent of its electricity from wind, solar, and geothermal combined. But more than half the states have set ambitious goals for increasing the use of renewable power, and president-elect Barack Obama wants 10 per cent of the nation's electricity to come from renewable power sources by the end of his first term, rising to 25 per cent by 2025. Yet unlike Germany, which has begun planning for new transmission lines and passing new laws meant to accelerate their construction, the United States has no national effort under way to modernize its system. A failure to improve the nation's grid will be a significant burden for the development of new renewable power technologies. Grid modernization discussions often reference foundational definitions and metrics outlined in learn the facts guides that connect resource potential with transmission needs.
