Alternative Energy Solar Power Explained

Alternative energy projects integrate solar PV, wind turbines, battery storage, and smart grid controls, using power electronics, inverters, and HVDC to optimize grid integration, reliability, and decarbonization in electrical engineering applications.

What Are Alternative Energy Projects?

Projects deploying renewables and storage with power electronics to ensure efficient, reliable grid integration.

✅ Solar PV, wind, and storage integrated via power converters

✅ Smart inverters, MPPT, and grid-forming control strategies

✅ HVDC links, microgrids, and protection coordination

Alternative energy projects are technologies that use alternative energy sources (wind energy, solar energy, among others) instead of conventional fossil fuels that damage the environment with toxic greenhouse (GHG) emissions. Natural Resources Canada (NRCAN) and the Department of Energy (DOE) are among some of the North American governmental organizations looking for ways to use alternative energy sources. While using the alternative energy source is important, so is educating the public about ways that they can someday use future alternative energy projects. Here are some energy systems the government is working on for your home: For a concise primer on definitions and policy context, see what alternative energy means to better frame the technologies discussed below.

Alternative Energy Projects - Home Solar Photovoltaic (PV) Systems

As one of several major categories, the forms of alternative energy place solar alongside wind, geothermal, and hydrogen options for residential planning.

This alternative energy project is a great way to preserve Earth's fossil-fuel resources and an efficient way to reduce air pollution. Another benefit of home PV systems is that it reduces the amount of power bought from local utilities thus making the residence less vulnerable to fluctuating price increases. A drawback to a home PV system are the extremely high installation costs, however, funding could be available from governments as an incentive to invest in alternative power. Unobstructed and clear access to the sun’s rays for most or all of the day is required throughout the year for well-designed PV systems. Location affects performance meaning that the roof of a house must be facing south (best option), east or west. Flat roofs are great options for solar electric systems because the PV modules are flat on the roof facing the sky or mounted on frames on an optimal angle facing south. One option for commercial application includes building structures that can create provide shade (such as window awnings) or covered parking. For homeowners evaluating PV feasibility, a detailed guide to solar power clarifies system sizing, orientation, and incentive considerations.

Alternative Energy Projects - Solar Concentrator System

Solar concentrators are alternative energy projects that track and focus the sun's energy; the sun's energy is then converted to hot water and space heat for day-to-day consumption. These alternative energy projects also have thermal storage, so it can distribute the sun's energy during the night or during a cloudy day. In addition to thermal applications, alternative energy power resources explain how concentrators integrate with broader energy management strategies.

Alternative Energy Projects - Hydrogen Electrolyzer

Hydrogen could be a valuable energy source in the future, so alternative energy projects are being funded by governments to heat residential homes. One such project, the hybrid hydrogen electrolyzer/high efficiency furnace system works by generating hydrogen from water using electricity. The generated hydrogen is then used to replace the natural gas that is conventionally used in furnaces. These hybrid energy systems can be installed in a variety of houses, including single detached houses. For system comparisons and component basics, an overview of alternative energy systems outlines how electrolyzers interface with storage and heating equipment.

Alternative Energy Projects - Geo Power

Geothermal Energy is also being used to provide heat to residential homes. One such alternative energy project, known as the Geo Power System, takes heat from the ground and sends it into the house. This tube-in-tube ground heat exchanger, made from polyethylene and aluminum is inserted vertically into a bore-hole in the ground either in the basement or crawlspace of a house. The alternative energy project is supposed to contribute energy during the winter months and absorb energy during the summer months in the ground. For site assessment and retrofit pathways, these alternative energy solutions highlight best practices for efficient geothermal installations.

Alternative Energy Projects - Solid-Oxide Fuel Cells

Fuel-cell combined heat and power (CHP) systems are alternative energy projects that can heat houses and provide hot water while electricity is sent to and from the electricity grid. The continued issues this residential alternative energy project faces include grid connection, thermal storage and proper fuel-cell size. To see how residential CHP fits within the wider clean energy mix, a primer on renewable and alternative energy offers context on adoption trends and grid impacts.

What alternative energy power technologies will make the largest impact? Alternative energy technologies have progressed so much in the past decade. However, some studies are starting to show that conventional power sources (such as fossil fuels and natural gas) will continue to have the lion's share of the world's energy mix for the next two decades. One study, conducted by the Boston Consulting Group, reports that forms of alternative energy power sources, such as wind power, will continue to provide smaller amounts of alternative energy power generation while other alternative energy power sources are ready to make a huge economic impact. Who? Let's take a look at the sources and their technologies. For readers new to the topic, this overview of what is alternative energy provides helpful context and definitions.

Alternative Energy Power - Solar Photovoltaic Technology

The BCG study predicts that solar PV (photovoltaic) will reach its cost competitiveness by 2015 to 2020 in the sunny regions of the world. However, the intermittency of PV's energy generation won't reach its full potential until technology breakthroughs are made in energy storage.

For practical insights, see how solar power in alternative energy is being deployed across different regions today.

Taking a look back into the last five years, it's clear that solar PV has significantly grown (up from 1.1 gigawatts in 2004 to 7.3 gigawatts in 2009, which is a 46 per cent annual increase). Today, solar panels are divided into two applications. Individual or small groups of panels can be used for distributed solar generation and larger groups of panels can be used to create utility-scale projects (also known as solar farms.) The underlying economics of the two applications are not that different, although solar farms can produce electricity at cheaper rates. Comparative data on renewable power generation helps benchmark PV performance against other resources.

Alternative Energy Power - Concentrated Solar Power Technology

Concentrated solar power (CSP) is another alternative energy power technology that is on its way to becoming a cost-competitive option - and soon (between 2015 and 2020). The beauty of this alternative energy power technology is that it can provide on-demand power through cost-effective thermal storage. Limitations to infrastructure and deployment barriers are significant, but surmountable.

Understanding the spectrum of renewable power sources clarifies where CSP complements wind and PV.

The generation potential of this alternative energy power solar resource over land is more than 100 times the total global demand for electricity. Solar energy without storage capacity technologies, such as thermal storage or hybrid solar-natural gas configuration, isn't reliable enough to be a sustainable energy source. However, CSP allows solar energy to play a larger part in the global electricity market and puts the alternative energy power source ahead of its alternative energy power counterparts. This perspective aligns with broader trends in renewable alternative energy adoption as grids adapt with storage and hybridization.

CSP is still small in terms of global power-generation capacity, but installed GSP capacity is expected to rise eightfold from 2009 (roughly one gigawatt) through 2015 (to more than eight gigawatts). Costs must drop for this alternative energy power technology to reach its full potential.

Cost curves are also influenced by policy and financing innovations within alternative energy solutions that scale deployment efficiently.

Alternative Energy Power - Smart-Grid Technologies

Many alternative energy power sources are capped due to their intermittent nature, but technologies like smart grid helps to accelerate their growth in the global energy marketplace.

A comprehensive view of the many forms of alternative energy underscores why flexibility is essential for balancing supply and demand.

By definition, a "smart grid" is a collection of equipment, infrastructure and information technologies designed to optimize the production, transmission and usage of electricity.

Incentives for smart-grid technologies include utility cost reduction, generation optimization and intelligent demand-response management. Smart-grid technologies improve the ability to integrate distributed generation and the ability to implement demand-response programs in intermittent energy sources such as wind energy and solar energy. Both factors are key enablers to expanding deployment in solar PV and wind technologies.

What is alternative energy? In electrical engineering, it denotes renewable power sources—solar PV, wind, hydro, geothermal—and enabling systems like power electronics, inverters, storage, microgrids, and grid integration to decarbonize electricity.

What Is Alternative Energy?

Alternative energy uses renewable electrical sources and grid tech to cut emissions and boost efficiency.

✅ Includes solar PV, wind turbines, hydro, geothermal, and bioenergy.

✅ Enabled by power electronics, inverters, converters, and smart grids.

✅ Integrates storage, demand response, and grid stabilization controls.

What is Alternative Energy? Alternative energy is power that comes from sources which are not going to run out, do not pollute as much as fossil fuels (oil, coal, natural gas), or do not create leftover materials that are harmful to people and the environment.

The term, "alternative," in a sense, is meant to contrast environment friendly energy against forms of energy that hurt the environment (coal power, natural gas, and oil power). Other names for alternative energy include clean energy, green energy and renewable energy. For readers new to the topic, you can explore concise summaries of technologies in the guide to forms of alternative energy to see how they compare.

Alternative Energy Vs. Renewable Energy

Renewable energy and alternative energy are often interchangeable, but they do have different meanings. Renewable energy comes from a replinishable energy source (it can never deplete). Electric energy that is generated from the sun (solar), the wind, the ocean (waves, currents or tides), the earth (geothermal), waste (biomass), landfill gas, or water (hydro power) is considered to be renewable energy. Renewable energy falls under the alternative energy umbrella because renewable fuel sources like wind and solar don't hurt the environment. For a broader overview, the relationship between categories like clean power and storage is outlined in the resource at renewable and alternative energy for further reading.

Alternative Energy Sources

A comprehensive overview of major options, deployment trends, and resource potential is compiled at alternative energy sources for additional context.

1. Alternative Energy as Solar Power

The sun has been around, shining on the earth with warmth and light for many, many years. This alternative energy source is available at no cost, and will be available to generate energy tomorrow and for millions of years to come, which explains why scientists continue to strive to figure out new ways on how to capture and use energy from the sun. For system basics, component choices, and siting tips, see alternative energy solar power to understand practical applications.

Long ago, it was discovered that leaving objects in the sun not only increased the object's thermal temperature, but the radiating heat also produced energy. Today, this type of alternative solar power, letting the sun heat something up, is called thermal solar energy. This alternative energy source is used to heat water for people's homes by passing cool water through pipes that are exposed to sunlight. As the pipes heat up, the water gets hot.

Another type of solar energy, known as light solar energy or photovoltaic energy, has only been used since the 1950s. This type of solar power comes from changing sunlight into actual electrical current. Very thin photovoltaic cells, which contain layers of different chemicals, absorb light from the sun and change it into electricity. The photovoltaic electricity is then stored in large batteries for later use, or it is actually sent back through the power lines to the electric company, which pays you for making electricity. Photovoltaic energy is growing in popularity every year. New types of photovoltaic cells, called “thin films”, are making solar electrical systems easier to put into homes, and less expensive than they were before.

Did you know: If one minute’s worth of all the sun’s energy that falls on the Earth was captured, it would be enough to provide the world with enough power for an entire year.

2. Alternative Energy as Wind Power

Wind energy has been utilized as an energy source for thousands of years. For example, the earliest sailors realized that putting sails on their boats to catch the wind made their boats go faster. More than 100 years ago, many farms used wind power to pump water from underground up to a container where it could be used for their homes or to water their animals. Today, wind power is used to turn large propeller blades that are put on top of towers. As the blades turn, their movement turns a generator, which changes the movement into electricity, which is sent to power stations or stored in batteries. Today, more people are buying small wind towers that make enough electricity to run their homes.

These days, very large windmills (known today as windfarms) are built in large groups. These windfarms are located miles away from where people live, and when the power is generated, the power is sent back to the cities and towns. Because wind patterns vary from location to location, some windfarms won’t work very well. But in windy areas, windfarms provide an efficient amount of electricity. Integrating wind with storage, efficiency, and grid modernization is covered under broader alternative energy solutions that help scale projects.

3. Alternative Energy as Water Energy (Hydro Electricity)

Water energy is another type of alternative energy that has been utilized for many years. Have you ever seen a water wheel next to a mill in an old painting or picture? The wheel was turned by the flowing water in a creek. The turning wheel was connected to a large millstone, which was used to crush grain to make flour and cornmeal. Today, electricity is generated using water. Large walls (dams) are built with tunnels to block flowing rivers so that the water can navigate through them, and, as the water goes through these tunnels, propellers turn a motor, which then generates electrical power. The generated power either is stored in batteries or is sent to a power station. Technology has developed enough that a small home can generate its own hydro power.

If a home is next to a creek or stream, a micro hydro system can turn a very small wheel, which then generates electrical power. Activists, scientists and some government officials have voiced their concerns that building large dams interrupt ecosystems, despite the fact that it generates millions of watts of power. However, the micro hydro technology can be used without hurting a small stream or the plants and animals that live there.

4. Alternative Energy as Biomass Energy

The farming industry, among other industries, are using corn and other plants as a biomass alternative energy source that can be put into the gas tanks of cars and trucks that can replace earth-damaging fossil fuels. Further feedstock pathways, conversion methods, and project case studies are outlined under biomass energy to illustrate real-world use.

The oldest type of biofuel is called biodiesel, which was first made out of plants and vegetables. Today, biodiesel is made out of old cooking oil and other types of plant materials that are not needed for other things. When it’s burning biodiesel made out of old cooking oil, the exhaust from a car’s tail pipe smells like french fries.

Ethanol, a second biofuel, is made by distilling plant materials (eg. corn) into grain alcohol, which is then mixed with small amounts of fossil fuel. When finished, this form of alternative energy can be used in cars, trucks and vans. While the farming industry is utilizing this readily available alternative energy resource, studies show that unless farms stop using petroleum-based chemicals for fertilizer and for killing pests, growing crops to make ethanol fuels may be more damaging to the environment than other forms of alternative energy. Comparisons with hydrogen, renewable diesel, and other alternative energy fuels highlight trade-offs in cost and lifecycle impacts.

Alternative energy cost analyzes LCOE, CAPEX, OPEX, and grid parity across solar PV, wind turbines, and battery storage, considering efficiency, load factors, and grid integration to optimize system design and lifecycle economics.

What Is Alternative Energy Cost?

Alternative energy cost is LCOE-based pricing for solar, wind, and storage, reflecting CAPEX, OPEX, and grid impacts.

✅ Uses LCOE comparing PV, wind, and storage across duty cycles.

✅ Includes CAPEX, OPEX, maintenance, and financing assumptions.

✅ Evaluates grid integration, curtailment, and reliability metrics.

Alternative energy cost is determined by how utilities typically set their rates and account for the cost differential between alternative energy and conventional energy sources. Basically, cost recovery of a utility’s investments and operating expenses determine electricity rates. For background on definitions and resource types, see this overview of what is renewable energy to align terminology across programs.

These alternative energy costs include:

Understanding the breadth of technologies captured under renewable alternative energy helps clarify why cost components vary by resource.

• owning generation
• owning transmission and distribution assets
• a return on owned assets
• purchased power contracts
• recovery of various operating expenses, including fuel costs, maintenance, and administration.

  Costs for generating, transmitting, and distributing electricity are in a utility’s rate. Because utility costs are bundled together, all generation resources are combined to create a utility “system mix” of generation. In other words, utilities do not normally distinguish between individual generation sources for their customers. Therefore, an equivalent mix of the utility’s generation resources and purchased power is provided to each customer. In practice, product structures for alternative energy power are designed to work within this system mix paradigm.

  For alternative energy cost determination, utilities and regulators are interested in separating the specific alternative energy costs related to securing green power. In this way, green power products are unique, differentiated electricity products. Since customer participation is voluntary, only those customers that choose to sign up for these programs pay the incremental costs. Alternative energy power program participants typically pay the higher alternative energy cost in the form of a premium on their monthly bill. In some jurisdictions, available alternative energy incentives help offset premiums for early adopters.

  Four Main Components In Determinating Alternative Energy Cost

• 1. The cost of the alternative energy source. This includes the total cost of electricity and/or environmental attributes from all alternative energy resources used in the product, whether from wind, solar, geothermal, biomass, or another source, and whether owned by the utility or acquired through a power purchase contract. For example, cost trajectories for alternative energy solar power have declined sharply in recent years due to technology improvements.
• 2. Program implementation costs. Any additional alternative energy costs attributed to implementing the alternative energy program, including administration and marketing. Utilities sometimes leverage alternative energy grants to defray outreach and administration expenses.
• 3. Ancillary services costs. The additional costs incurred to integrate variable output resources, particularly wind, into a utility’s system.
• 4. Displaced utility generation (and capacity) resource costs. The renewable resource displaces electricity that the utility would otherwise have generated or purchased.

   

  In conclusion, alternative energy costs can be represented as: Alternative energy premium = (1) + (2) + (3) – (4)

  Alternative Energy Cost Determination

  Alternative energy costs are captured through the specific power purchase agreements for alternative energy (in this case, the term alternative energy is interchanged with renewable energy) or RECs (renewable energy contracts), or through the regulatory approval process for utility-owned renewable projects. As long as these are tracked separately from the rest of the generation mix, the appropriate alternative generation costs can be determined. However, generation costs are hard to determine because it's uncertain how many customers plan to enroll in the program and how long they plan to participate. In electric markets that have not gone through restructuring from the electric industry, contracts for generation are typically long-term (10 years or more), and investment in owned facilities is generally considered to be for the life of the facility (20 years or more). For readers new to key terms and market structures, this primer on renewable energy facts provides helpful context for interpreting contract and REC pricing.

  The long-term nature of the resource commitment severely contrasts with the program subscription commitment required of most customers. Most alternative energy programs do not require that customers enroll for a specific term, much less sign up for 10 or 20 years to match the facility or contract life of the renewable power supply source. Therefore, while the annual cost of renewable energy is straightforward to determine, the utility faces some level of risk that will likely be reflected in the product pricing.

  However, if the utility is also subject to a renewable portfolio standard and is therefore required to procure a certain fraction of renewable energy for its overall load, there may be less risk, because the utility has greater flexibility in managing its overall renewable portfolio between its compliance and voluntary program obligations.

Alternative energy geothermal delivers baseload renewable electricity via hydrothermal reservoirs, binary-cycle ORC turbines, and EGS, using heat exchangers, generators, and power electronics for efficient grid integration, low emissions, and stable capacity.

What Is Alternative Energy Geothermal?

It converts subsurface heat to electricity via steam or ORC cycles, generators, and grid-tied power electronics.

✅ ORC and flash steam cycles drive turbines and synchronous generators

✅ Power electronics, inverters, and transformers enable grid integration

✅ EGS, drilling, and heat exchangers expand capacity with low emissions

Geothermal energy comes from heat stored beneath the Earth's surface. Also known as thermal energy, geothermal is considered to be an alternative energy because it produces very little greenhouse gas emissions (GHG), which harm the Earth once it's generated into electricity. Geothermal wells release these greenhouse gases, but not nearly as much as its fossil fuel counterparts oil and coal. For context on how this resource fits within energy policy, see our overview of what is alternative energy to understand key definitions.

Alternative energy geothermal is a product from Earth's original formation: radioactive decay of minerals thanks to volcanic eruptions and solar energy digested and stored from the Earth's surface. Thermal energy is produced from the continuous conduction of heat that emanates from the Earth's core that moves upward to the surface. This process is known as the geothermal gradient. If you've ever had the opportunity to bathe in hot springs, you'll be glad to know that the thermal heat comes from beneath the Earth. When comparing technologies, placing geothermal alongside other alternative energy sources highlights its base-load role and unique subsurface dependence.

Alternative Energy Geothermal - How can we use it?

In practice, many integrated alternative energy systems combine geothermal with insulation and smart controls to maximize year-round efficiency.

Energy producers have been able to convert alternative energy geothermal into electricity. These same producers have high hopes for geothermal energy because power can be generated 24 hours a day, unlike other intermittent renewable energies, like wind energy and solar energy. This contrasts with the variability seen in resources such as solar power during cloudy periods or at night.

Geothermal energy can also be used to heat pumps or for other direct uses such as cooling and heating buildings. The Earth's crust temperature a few feet below is buffered to a constant seven to 14 °C (45 to 58 °F), so a liquid can be pre-heated or pre-cooled in underground pipelines, providing no-cost cooling during the summer, and with a heat pump, heating during the winter months. Other direct uses include aquaculture, agriculture (greenhouses), and industry. Project planners often consult practical alternative energy solutions to evaluate lifecycle costs and integration pathways.

Alternative Energy Geothermal - How is geothermal electricity produced?

Within the broader family of forms of alternative energy, geothermal distinguishes itself through high capacity factors and minimal fuel risk.

Geothermal energy uses Earth's natural heat to generate electricity. Geothermal plants are built on or near reservoirs that contain Earth's hydrothermal resources (underground steam and heated water). The heat mining process begins when drills penetrate these reservoirs to obtain the steam and water to power electricity-generating turbines.

There are different ways to produce alternative energy geothermal. Two popular processes include:

• Flash Steam Geothermal water with temperatures exceeding 350°F is extracted under extremely high pressure by flash steam plants. When the heated water surfaces, a sudden pressure reduction causes some of the hot water to flash off as steam. This flashed steam operates a generator, at which time, the extracted steam and water are reintroduced into the geothermal reservoir.
• Dry Steam Dry steam is extracted directly from under the earth’s surface by dry steam plants to operate a generator. When the steam condenses into water, it is then reintroduced into the alternative energy geothermal reservoir.

   

  Alternative Energy Geothermal - Is Geothermal Energy a Sustainable Energy Source?

  Alternative Energy Geothermal is considered to be sustainable, cost-effective, great for the environment and reliable. Recent advances in technology have expanded alternative energy geothermal applicable uses (such as home heating), which could lead to global exploitation. However, advances in technology, cost, government incentives and implementation of geothermal power projects will determine if alternative energy geothermal will become a viable global competitor.

  Alternative Energy Geothermal - Is Geothermal Energy a Renewable Energy Source?

  Scientific evidence shows that geothermal sites can provide heat for many decades, but eventually these specific locations cool down, which brings into question if alternative energy geothermal truly is a renewable energy source, since renewables are defined as green energy sources that never deplete. Understanding how geothermal fits into renewable alternative energy frameworks can help policymakers set realistic targets.

Biomass energy converts organic feedstocks into renewable power via combustion, gasification, and anaerobic digestion, enabling CHP systems, grid integration, carbon-neutral generation, improved thermal efficiency, and dispatchable biofuels for resilient electrical infrastructure.

What Is Biomass Energy?

Biomass energy produces electricity from feedstocks through combustion or digestion, enabling CHP and grid reliability.

✅ CHP raises electrical efficiency to 70% with heat recovery

✅ Gasification feeds syngas to turbines or SOFC for power

✅ Dispatchable output supports frequency and voltage stability

Biomass energy comes from biomass feedstock (crops and residues, farm animal wastes, industrial wood, etc.). The heat from this substantial renewable resource can generate electricity, fuel and other forms of energy. It has been estimated that just one eighth of the total biomass energy produced annually could provide all of humanity’s current demand for energy. For a deeper overview of how biomass fits within the clean energy landscape, see this guide on biomass renewable energy and its practical applications today.

Some forms of biomass fuels (or biofuels), derived from biomass feedstock, can be solid, liquid, or gas. Kitchen scraps, sewage, the leftovers of the food processing industries, paper, sawdust, and lawn clippings are some of the available biomass energy sources. Biomass energy has received a lot of attention because an opportunity to convert waste into something very valuable has presented itself. These pathways are often discussed alongside other forms of alternative energy that leverage different feedstocks and conversion methods.

Biomass Energy – How can we use it?

Biomass energy can be converted to generate electricity, fuel vehicles and heat buildings using biofuel technologies. At the moment, biomass energy sources used in power plants include agricultural and farm residues, food processing residues, wood residues and methane gas from land fills. Biomass energy producers hope to significantly expand the supply of biomass energy by using trees and grasses as well. In power markets, biomass can contribute to renewable electricity portfolios alongside wind and solar resources.

Currently, there are more than 350 biomass energy plants generating 7,000 megawatts of biomass power in the United States. The producers who own these plants are quite diverse; they range from the electrical utilities, independent power producers, the wood manufacturing industry, and the pulp and paper industry. Such facilities are part of broader trends in renewable power generation that emphasize reliability and grid integration.

Biomass energy is considered a renewable energy source because it can replenish itself (regrown), unlike fossil fuels such as coal and oil, which when used, are gone. And, unlike coal and oil, biomass energy is an alternative energy source because it doesn’t hurt the environment with harmful chemicals, such as carbon dioxide, which cause greenhouse gas emissions (GHG). Using renewable biomass resources not only reduce greenhouse gases, but they also reduce air pollutants and landfill wastes. This classification aligns with definitions of alternative energy that prioritize low emissions and resource sustainability.

As policies evolve, many jurisdictions frame biomass within broader renewable alternative energy strategies that support decarbonization goals.

Biomass Energy in Today’s Marketplace

Within the spectrum of renewable energy sources, biomass competes and collaborates with wind, solar, and hydro depending on local resource availability.

• High costs in handling and transportation, as well as high moisture content, have long outweighed the low price of biomass energy feedstocks. Fuels that are filled with moisture are hard to burn properly and heat release is slow and hard to control. However, fuel upgrading options, such as pelletization and drying remedy this situation, thus making biomass energy more economically attractive.
• Biomass energy can also make be useful in blending and co-firing applications with coal because of the low SO2, NOx, and metals emissions from biomass energy fuels, and their CO2 neutral status.

Biomass Energy – Benefits of Cogeneration

Cogeneration, the practice of producing both electricity and useful heat, is a great way of improving energy efficiency. Some sawmills, for example, use a lot of heat from boilers powered by biomass energy to supply energy to their kiln-drying operations. But any extra heat can help gasify biomass energy fuels so they can be used in a gas turbine, which is more efficient than a simple steam boiler. Additional savings can be produced by using combined cycle technology, which takes additional waste heat from the gas turbine to give power to a steam-driven turbine.
