What is Distributed Generation? Explained

Wind Turbine Theft an Emerging Threat to Renewable Energy Infrastructure drives copper theft, SCADA breaches, and component vandalism, undermining grid reliability, power electronics, asset monitoring, and substation security via weak telemetry and inadequate intrusion detection.

Why Is Wind Turbine Theft an Emerging Threat to Renewable Energy Infrastructure?

It compromises SCADA, power electronics, and grid protection, causing outages, safety risks, and costly downtime.

✅ Targets copper, rare-earths, converters; degrades power quality.

✅ Exposes SCADA/PLC networks; weak auth and unpatched firmware.

✅ Disrupts protection relays, yaw/pitch control, and grid code compliance.

As the global energy landscape shifts towards sustainability, wind power has emerged as a cornerstone of renewable energy. However, a growing concern is threatening the integrity of this clean energy source: the theft of wind turbine components. This issue not only undermines the efficiency of wind farms but also poses significant economic and operational challenges. As stakeholders evaluate risk, understanding the fundamentals of renewable energy provides perspective on how theft disrupts larger decarbonization goals.

The Scope of the Problem

Wind turbines are complex machines composed of various valuable components, including copper wiring, rare earth magnets, and electronic systems. These materials are attractive targets for thieves due to their high resale value. Incidents of theft have been reported globally, with turbines being dismantled and parts sold on the black market. In some cases, entire turbines have been stolen, leading to substantial financial losses for operators. Industry primers such as renewable energy facts outline why critical materials attract theft in secondary markets.

Economic Implications

The financial impact of turbine theft is multifaceted. Beyond the immediate loss of equipment, operators face increased insurance premiums, higher maintenance costs, and potential fines for non-compliance with safety regulations. The theft of components also leads to extended downtimes as replacements are sourced, further affecting energy production and revenue. These losses ripple into PPA obligations and grid forecasts, as disruptions reduce expected renewable power output during peak demand windows.

Security Measures and Challenges

To combat this growing threat, wind farm operators are implementing enhanced security measures. These include installing surveillance cameras, employing security personnel, and utilizing GPS tracking systems for turbine components. Despite these efforts, the vast and often remote locations of wind farms make them difficult to monitor effectively. This challenge is compounded by the rapid pace of technological advancement, which can outstrip the implementation of security protocols. Blended approaches that pair physical hardening with community engagement have proven effective across other renewable power sources in similarly remote locations.

Legal and Regulatory Responses

Governments and regulatory bodies are beginning to recognize the severity of turbine theft. In some regions, legislation has been introduced to regulate the sale of second-hand turbine components and to impose stricter penalties for theft. However, enforcement remains inconsistent, and the international nature of the wind energy supply chain complicates efforts to track and recover stolen goods. Clearer resale controls also protect consumer confidence in certified renewable electricity markets and warranty frameworks.

Broader Implications for Renewable Energy

The theft of wind turbine components highlights a broader issue within the renewable energy sector: the vulnerability of infrastructure to criminal activity. As the industry grows, so too does the potential for exploitation by organized crime. This underscores the need for comprehensive security strategies that encompass not only physical protection but also cyber defenses to safeguard against a range of threats. Coordinated intelligence sharing across operators of diverse renewable energy sources can expose cross-site patterns and organized groups.

Conclusion

While wind energy remains a cornerstone of the global push towards sustainability, the theft of turbine components presents a significant challenge that must be addressed. Through a combination of enhanced security measures, stricter regulations, and international cooperation, the renewable energy sector can mitigate this threat and continue to provide clean, reliable power for the future. Doing so strengthens public trust in clean renewable energy systems that communities increasingly rely upon.

Renewable energy credits certify MWh-scale green generation, enabling GHG accounting, Scope 2 reductions, RPS compliance, and PPA hedging via registries like WREGIS, GATS, and M-RETS for grid decarbonization and utility procurement strategies.

What Are Renewable Energy Credits?

Tradable 1 MWh certificates for renewable generation, used in Scope 2 accounting, RPS compliance, and decarbonization.

✅ Verifies MWh via meter data and ISO/RTO registry tracking

✅ Enables Scope 2 reductions for facilities and microgrids

✅ Supports RPS compliance and PPA procurement strategies

Renewable Energy Credits, otherwise known as Renewable Electricity Certificates, or Tradable Renewable Certificates (TRCs), are tradable, non-tangible energy commodities that represent proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource (renewable electricity). For context on how clean generation is delivered and tracked, see renewable electricity fundamentals and related attributes.

Renewable Energy Credits can be sold and traded or bartered, and the owner of the REC can claim to have purchased renewable energy. While traditional carbon emissions trading programs promote low-carbon technologies by increasing the cost of emitting carbon, RECs can incentivize carbon-neutral renewable energy by providing a production subsidy to electricity generated from renewable sources. It is important to understand that the energy associated with a REC is sold separately and is used by another party. The consumer of a REC receives only a certificate. These market incentives often complement policies such as renewable energy tax credits that influence project financing.

In states and provinces that have a REC programs, a green energy provider (such as a wind farm) is credited with one REC for every 1,000 kWh or 1 MWh of electricity it produces (for reference, an average residential customer consumes about 800 kWh in a month). A certifying agency gives each REC a unique identification number to make sure it doesn't get double-counted. The green energy is then fed into the electrical grid (by mandate), and the accompanying REC can then be sold on the open market. Understanding the range of renewable energy systems that can issue RECs helps stakeholders assess performance and eligibility.

Renewable energy power companies benefit from RECs because they serve as an incentive. Many non-renewable energy sources are subsidized, making it difficult for green energy companies to survive. By being able to sell the power and RECs, the company can afford to thrive in the market. Prices for RECs vary widely, just like other commodities, and they are available for sale in numerous locations. Price signals can also vary with the mix of local renewable energy sources and transmission constraints.

By purchasing Renewable Energy Credits, consumers can claim that they are supporting green energy. While a consumer would ideally also purchase renewable energy for his or her home, this is not always possible. RECs allow companies and individuals to support power in areas which do not offer it directly. Consumers should also, of course, practice conservation and work to get green power in their area, but RECs are a good place to start. For companies, they are an important part of doing business responsibly, while thinking about future generations. For households unable to procure green tariffs, RECs align with broader clean renewable energy practices and ongoing efficiency efforts.

Along with carbon offsets and other incentive programs, Renewable Energy Credits are part of a growing movement which acknowledges that even small changes make a big difference. By supporting green energy, consumers show that there is a demand for it, and companies can build more plants or accelerate production with the funds raised through the sale of RECs. Organizations which promote programs like this hope to eventually see everyone's ecological footprint, meaning the amount of resources and space needed to support a particular lifestyle, greatly reduced. Clear explanations of what is renewable energy empower buyers to request credible products and disclosures.

What's the difference between a REC and a Carbon Offset?

All RECs from qualifying new generators represent the environmental attributes of renewable power, principally the fact that producing that power causes less, or no, pollution. When you buy an amount of wind-generated Renewable Energy Credits equal to your electricity consumption, you are legally entitled to claim that you are wind powered, and that your electricity use does not contribute to global warming. In other words, all wind Renewable Energy Credits can convert your electricity to wind power. However, for a REC to be used to offset emissions from driving, flying or heating your home, it must be from a project that would not have been implemented without the opportunity to realize revenues for the carbon reductions (in other words, it must be "additional" to business-as-usual - see "what's the importance of additionality, below"), and not all renewable energy projects can say that. To evaluate such claims confidently, consult resources that present renewable energy facts and common verification methods.

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.

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.

✅ High-efficiency CHP improves capacity factor and voltage stability.

✅ Power electronics, inverters, and protection enable grid-tie.

✅ Supports frequency control, reactive power, and microgrid resiliency.

Biomass Renewable Energy is an important source of energy for majority of the world’s population. The use of biomass renewable energy is expected to increase in the near future, with growth in population. In many under developed nations (most especially areas such as parts of Africa, conventional biomass renewable energy dominates national energy strategies, leading to negative impacts on human health and the environment. There are, however, opportunities for developing improved and modern biomass energy technologies, which offer substantial benefits in terms of enhanced quality of energy services and reduction in negative health and environmental impacts. For a concise overview of feedstocks, conversion technologies, and benefits, see this biomass energy overview to understand core concepts.

In addition, the sustainable harvesting of biomass renewable energy resources is essential for ensuring the continued availability of this important energy source particularly for the world’s poor.

Sustainable harvesting practices also align with broader categories of renewable energy sources that emphasize resource regeneration.

Biomass renewable energy plays a vital role in meeting local energy demand in many regions of the developing world. Biomass is a primary source of electrical energy for about two billion people in developing countries. Therefore, it's available to the world’s impoverished nations while providing a suitable energy for cooking and heating. Also, biomass energy-based industries are a chief source of economic development in terms of job creation in rural areas. Modern biomass renewable energy technologies are being widely used in many developing countries as well as in certain parts of the developed world. With proper energy management strategies, supported by appropriate environmental practices, modern biomass renewable energy projects can be a sustainable source of electric power production as well as providing liquid and gaseous fuels. Biomass is therefore not only a central alternative energy source but is probably an important future sustainable energy source. These outcomes contribute to the goals of clean renewable energy that balance access, affordability, and environmental performance.

Growing interest in biomass renewable energy is driven by the following facts among others:

• It can contribute to lessening poverty in developing countries;
• Biomass renewable energy meets power needs without expensive conversion equipment;
• It can deliver biomass renewable energy in all forms that countries need for electricity and heating (in all forms of liquid and gaseous fuels)
• It is carbon dioxide-neutral because as much biomass can be grown as burned
• Biomass renewable energy helps to restore unproductive and degraded lands.

For definitions, policy basics, and key technologies, this guide to renewable energy offers helpful background.

Available statistics indicate that the share of biomass renewable energy in the global energy consumption has remained roughly the same over the last 30 years. Biomass renewable energy accounted for an estimated 14% and 11% of the world’s final energy consumption in 2000 and 2001 respectively (IEA, 1998 and IEA, 2003). The International Energy Agency (IEA) estimates that at global level, the share of biomass in total final energy consumption is comparable to that of electricity (15%) and gas (16%). These figures parallel developments in renewable electricity that are influencing investment and grid planning.

Modern biomass renewable energy technologies have the potential to provide improved energy services based on available biomass resources and agricultural residues19. Widespread use of combined heat and power generation biomass renewable energy options in rural areas can address multiple social, economic and environmental issues that now constrain local development. The availability of low cost biomass power in rural areas could help provide cleaner, more efficient energy services to support local development, promote environmental protection, provide better domestic fuel sources and improve rural life. Bioenergy technologies based on sustainable biomass supply are considered "carbon neutral" and may lead to net carbon dioxide emission reduction if used to replace fossil fuels. For comparative emissions data and lifecycle insights, consult this overview on renewable energy facts to understand trade-offs.

In addition, modern biomass renewable energy technologies can contribute to better bio-waste management. For example, land-fill gas can assist urban waste management, while bagasse-based co-generation reduces the problem of safe disposal of bagasse at sugar plantations. Another advantage of modern biomass renewable energy is its job generation potential – a very important attraction for many developing countries faced with chronic levels of unemployment or under-employment. Existing studies indicate that, in comparison to other primary energy sources, the job generation potential of modern biomass is among the highest. For example, in Brazil, the annual production of 14 billion litres of ethanol from sugarcane is responsible for the creation of 462,000 direct and 1,386,000 indirect jobs in the country, corresponding to a rate of 263,000 annual jobs per MTOE generated. Collectively, these pathways situate biomass within broader renewable alternative energy strategies that enhance resilience and jobs.
