What Is Renewable Energy?
Renewable energy is energy that comes from sources that can be replenished naturally and do not run out, unlike fossil fuels such as coal, oil, and gas. Renewable energy sources include solar, wind, hydro, biomass, and geothermal energy. These sources can be used to generate electricity, heat, or fuel for various purposes.
Renewable energy is no longer a niche experiment, it is a fast-growing part of the U.S. energy system. According to the U.S. Energy Information Administration (EIA), renewables supplied about 24% of total U.S. electricity generation in 2024, up from about 23% in 2023, with wind (~10% of total generation, the largest renewable source) and solar (~7%, the fastest-growing) leading the way. Looking at the entire energy system, renewable energy accounted for about 9.1% of total U.S. energy consumption in 2024 (our calculation from EIA’s figures), a record 8.6 quadrillion BTU of renewables out of 94.2 quadrillion BTU consumed nationwide.
The momentum behind renewables keeps building. In 2024, a record 30 gigawatts of utility-scale solar joined the U.S. grid, accounting for 61% of all newly added electricity-generating capacity³. Meanwhile, battery storage is growing at a remarkable pace: U.S. providers added a record 10.3 GW of utility-scale battery storage in 2024³. In this blog post, we will share what renewable energy is, why it matters, and how you can use it at home.
Why Is Renewable Energy Important?
Renewable energy is important for several reasons:
- Environmental reasons – Renewable energy helps reduce greenhouse gas emissions that cause global warming and climate change. It also helps reduce air pollution, water pollution, and land degradation that result from fossil fuel extraction and combustion. Renewable energy can also protect biodiversity and ecosystems by reducing habitat loss and fragmentation.
- Economic reasons – Renewable energy can help lower energy costs for consumers and businesses by reducing dependence on imported fossil fuels. It can also create jobs and income for local communities by stimulating the development of new industries and services. Renewable energy can also enhance energy security and resilience by diversifying the energy mix and reducing the risk of supply disruptions.
- Social reasons – Renewable energy can help improve the quality of life and health of people by providing access to clean and affordable energy, especially in rural and remote areas. It can also empower women and marginalized groups by increasing their participation in the energy sector and decision making. Renewable energy can also foster social cohesion and peace by reducing conflicts over scarce resources.
How Can You Use Renewable Energy at Home?
As a homeowner, you can use renewable energy at home in various ways:
- Go solar – Install solar panels on your roof or backyard to generate your own electricity from sunlight. You can also use solar water heaters to heat your water using solar thermal energy. Before committing, get multiple solar quotes from reputable installers or a solar quote marketplace to compare pricing, warranties, and system sizes for your roof — and check current local and state incentives, which can meaningfully affect the final cost.
- Add battery backup – Pair your solar panels with a home battery to store excess daytime energy for the evening or for outages. Even without solar, a home battery can shift your grid usage to cheaper off-peak hours in some utility rate plans. Battery storage is deploying fast at utility scale — make sure the warranty and capacity match your actual backup needs.
- Invest in energy-efficient appliances, lighting, heating, and cooling systems – These use less electricity and reduce your energy bills. You can also use smart thermostats and power strips to control your energy usage remotely or automatically.
- Switch to green electricity providers – Some utilities and retailers offer electricity from renewable sources such as wind, hydro, or biomass through green tariff programs. You can also join community solar or wind projects that allow you to share the benefits of renewable energy with your neighbors, without installing anything on your own property.
- Plant trees and shrubs around your home – They provide shade, insulation, and oxygen. You can also grow your own food in a garden or a greenhouse using organic methods.
- Reduce your waste and recycle as much as possible – You can also compost your organic waste and use it as fertilizer for your plants.
- Monitor your energy use – Many utilities offer free online dashboards or smart-meter portals that show your hourly electricity consumption. Knowing when you use the most power helps you size solar, batteries, and efficiency upgrades correctly — and can reveal cheap off-peak hours to shift laundry or dishwashing into.
By using renewable energy at home, you can not only save money and improve your comfort, but also contribute to a cleaner and greener future for yourself and the world.
Conclusion
Renewable energy, solar, wind, hydro, biomass, and geothermal, is a fast-growing part of how America powers itself, supplying roughly one quarter of U.S. electricity in 2024 and adding record amounts of new capacity every year. It matters because it reduces emissions and pollution, supports local jobs and energy security, and gives households cleaner, more affordable energy options. As a homeowner, the smartest first steps are to reduce wasted energy with efficient appliances, then explore solar quotes, community solar, or a green electricity plan to start powering your home with renewables. It’s a win-win situation for you and the planet!
