Can You Create Your Own Renewable Energy?

Can you create your own renewable energy?

Renewable energy is becoming an increasingly important part of meeting our energy needs. In 2020, renewable energy sources accounted for about 12.6% of total U.S. energy consumption and 19% of electricity generation ( With concerns about climate change and energy independence growing, there is strong interest in expanding the use of renewable energy from sources like wind, solar, geothermal, hydroelectric, and biomass.

There are a variety of ways that individuals can utilize renewable energy in their own homes. Installing solar panels, small wind turbines, or geothermal heat pumps can help households generate their own clean electricity or heating/cooling. Homeowners might also use wood pellets or biofuel in boilers for home heating. While upfront costs can be high, renewable energy systems can pay for themselves over time through utility bill savings. There are also often financial incentives available.

This article provides an overview of the major renewable energy options available for homeowners to produce their own clean energy. We will explore solar, wind, geothermal, hydro, and biofuel systems. Key considerations, costs, incentives, and the future outlook will also be discussed to help homeowners understand the possibilities for generating renewable energy at home.

Solar Energy

Solar panels generate electricity directly from sunlight through the photovoltaic effect. Solar cells made from silicon convert photons from sunlight into electricity through the photovoltaic effect. Multiple solar cells are connected together to form solar panels. The direct current (DC) electricity generated by solar panels must be converted to alternating current (AC) using an inverter for most household uses.

The advantages of solar power include reduced electricity bills, energy independence, and environmental benefits. Solar energy produces no greenhouse gas emissions during operation. The main disadvantages include the relatively high upfront cost of solar panel systems and variability in energy production depending on weather and time of day 1. However, costs have dropped significantly in recent years making solar more affordable.

For homes, solar panels can be installed on rooftops or ground-mounted structures. A typical 5kW rooftop solar system may require 15-25 panels. The specific solar panel setup depends on factors like roof space, electricity needs, local weather and incentives. Many homeowners start with a 3-8kW system which can offset 30-60% of electricity usage 2.

Wind Energy

Wind turbines generate electricity through a process called wind energy conversion. When the wind blows, it spins the blades of the turbine, which causes a shaft inside to rotate. This shaft is connected to a generator, which converts the mechanical energy of the spinning shaft into electrical energy. The electricity is then fed into the grid for homes and businesses to use. Some key pros of wind power include:

  • It’s a renewable energy source
  • It produces no greenhouse gas emissions
  • Wind turbines can be built on existing farms or ranches
  • It diversifies the energy supply and reduces dependence on fossil fuels

Some cons include:

  • The power output depends on the wind speed, so it’s intermittent
  • Good wind sites are often located far from cities where the electricity is needed
  • Wind turbines can impact wildlife habitats and migration patterns

For residential uses, small wind turbines designed for homes, farms, or small businesses are available. According to the American Wind Energy Association, small wind turbines cost between $3,000 and $10,000 per kilowatt of capacity. This means a 5 kW turbine could cost from $15,000 to $50,000 installed (Source). Factors like tower height, location, and local permits and installation costs impact the overall price. Popular options for residential wind turbines include models from Bergey, Eclectic Energy, and Windtronics.

Geothermal Energy

Geothermal energy harnesses heat from the Earth to generate renewable electricity and provide heating and cooling. The geothermal energy used for electricity comes from hot water reservoirs located deep underground. Wells are drilled into these reservoirs to bring the hot water to the surface. The steam from this hot water rotates turbines that generate electricity. For heating and cooling, geothermal energy uses the constant temperatures near the surface of the Earth. Pipes called geothermal heat pumps or ground source heat pumps are buried in the shallow ground to control building temperatures.

According to the U.S. Energy Information Administration, geothermal energy accounted for 0.4% of total U.S. electricity generation and 3.7% of total renewable electricity generation in 2020. The western states where geothermal resources are concentrated, like Nevada and California, rely on geothermal for a much greater share of their electricity.

Some pros of geothermal energy include its reliability as a baseload power source, low emissions, and sustainability when resources are properly managed. Cons include high upfront costs for geothermal plants, potential for depletion if used faster than reservoirs are replenished, and location limitations based on geologic requirements.

For residential geothermal systems, heat pumps use stable ground temperatures near the Earth’s surface to control heating and cooling. According to the Center for Sustainable Systems, around 600,000 U.S. homes used geothermal heat pumps as of 2020. Geothermal systems can reduce energy use for heating and cooling by 25-60% compared to conventional systems. Upfront installation costs are higher but pay back over 5-10 years through energy savings.

Micro Hydro Power

Micro hydro power generates electricity by harnessing the energy from flowing water. Small hydro turbines can generate energy from rivers and streams on a small, residential scale (Malhan, 2021). These micro hydro setups divert flowing water through a pipe and into a turbine, which spins to generate electricity.

Some benefits of micro hydro power include its renewable nature, low operating costs after installation, and independence from the electrical grid. However, micro hydro does require suitable flowing water near the home, and the upfront installation costs can be prohibitive for some homeowners. Permits and regulations may also complicate residential micro hydro projects.

There are examples of successful residential micro hydro projects. One homeowner in California installed a 1.5 kW system to take advantage of the flowing creek near his property. This provided enough electricity to power his entire off-grid home. With the proper site conditions and investment, micro hydro can provide electricity without any fuel costs or carbon emissions (Dorji, 2007).


Biofuels are fuels produced directly or indirectly from organic matter. Some common biofuels include wood, charcoal, biogas, and bioalcohol. Biofuels can provide a renewable energy source as the organic materials used to produce them can be replenished.

Some pros of using biofuels include:

  • Biofuels are renewable, as crops and other organic materials used to produce them can be regrown.
  • Biofuels emit less greenhouse gases compared to fossil fuels.
  • Biofuels can provide energy security by relying on domestically produced crops.

Some cons of using biofuels include:

  • Large areas of land are needed to grow the crops used for biofuels, which can compete with food production.
  • Some biofuel production methods are not energy efficient.
  • Biofuels can be expensive to produce compared to fossil fuels.

In the residential sector, wood and biomass are commonly used biofuels. Approximately 2.6% of U.S. homes used wood as the main heating fuel as of 2020 [1]. Wood can be burned directly for heat or converted to wood pellets. Using wood for residential heating avoids fossil fuels but does produce air pollution.

Biogas produced from organic waste like food scraps and manure can also be used residentially for heating and cooking. Around 1,500 U.S. households used biogas for heating as of 2020 [1]. Biogas avoids fossil fuel use and reduces methane emissions from waste.


The upfront costs of renewable energy systems like solar panels or wind turbines can be significant. According to research from Science Direct, the levelized cost of energy (LCOE) for off-grid solar PV systems has dropped from $6/kWh in 1984 to under $0.50/kWh in 2020 (Weinand, 2023). However, an average 5 kW solar array can still cost $15,000-$25,000 installed. The availability of renewable resources depends heavily on location – solar in the American Southwest, wind in the Great Plains, geothermal near tectonic plates. Zoning, permits, and regulations vary significantly by county and state. While connecting to the existing electric grid is easier, off-grid systems offer energy independence and long-term savings on utility bills. An off-grid renewable system from Energy5 can offer over 60% lifetime energy cost savings compared to utility costs (Energy5, 2023).

Financial Incentives

There are a variety of financial incentives at the federal, state, and local level available for renewable energy systems. These incentives help offset the upfront costs of installing renewable energy like solar panels or wind turbines.

The recently passed Inflation Reduction Act of 2022 includes substantial renewable energy tax credits. There is a 30% federal solar tax credit for installing solar panels on residential properties that runs through 2032. There are also tax credits of up to 30% for installing solar battery storage systems. For wind turbines and geothermal systems, there is a 30% investment tax credit that runs through the end of 2032. See Summary of Inflation Reduction Act for more details.

Many states and utilities offer additional renewable energy incentives and rebates. For example, the state of Washington has a Renewable Energy System Incentive Program that provides cash incentives for solar electric, solar water heating, wind, and anaerobic digester systems. See Renewable Energy Incentives in Washington for details.

Check with your state energy office and local utility to find available incentives in your area. The incentives can significantly offset the upfront costs of installing a renewable energy system.

Future Outlook

The future looks bright for residential renewable energy. As prices continue falling and new technologies emerge, home renewable energy systems are experiencing growing adoption. According to a 2021 report, over 2 million homes in the United States have installed solar panels, and that number is projected to reach 5 million by 2025 (Source). Residential solar capacity is expected to triple in the next 5 years as more efficient solar panels and batteries become affordable for homeowners (Source).

Advances in wind and geothermal technologies are also making residential renewable energy more viable. Small wind turbines and ground source heat pumps are seeing growing adoption. It’s estimated that 9% of new U.S. homes will utilize geothermal heating and cooling by 2030 (Source). Overall, projections indicate that 25% of U.S. households could meet a majority of their energy needs through residential renewable power within the next decade.


As we’ve seen, there are a variety of renewable energy technologies that homeowners can implement on their properties to reduce reliance on fossil fuels and utility grid power. From rooftop solar panels to small backyard wind turbines to geothermal heat pumps, generating your own clean energy is more feasible today than ever before.

The future is bright for home renewable energy systems as costs continue to fall and technology improves. Innovations in battery storage, smart grids, and energy efficiency make on-site generation even more accessible and cost-effective. New financing options also remove upfront barriers to adopting renewables.

For readers interested in energy independence through renewables, simple steps to get started include: conducting a home energy audit, researching incentives and policies in your area, consulting with qualified installers, starting small with achievable projects, and scaling up over time as technology advances.

With a thoughtful approach and long-term commitment, many homeowners can realistically meet a significant portion of their energy needs sustainably. The personal and environmental benefits make home renewable energy systems an investment well worth considering.
