In 2022, renewable energy provided about 13% of the total U.S. energy consumption, and it is projected to continue to increase through 2050. Globally, renewable energy sources account for over 42% of electricity generation, with the share of wind and solar PV doubling to 25%.

The United States is a resource-rich country with abundant renewable energy resources, with the amount available being 100 times that of the nation’s annual electricity need. The use of renewable energy is essential for decarbonizing energy systems and mitigating climate change.

Types of Renewable Energy

Renewable energy comes from sources that are naturally replenished and can be sustained over the long term. Here are some types of renewable energy, including:

Examples of Renewable Energy Resources:

• Solar energy
• Wind energy
• Hydro energy
• Geothermal energy
• Biomass energy
• Tidal energy
• Hydrogen fuel cells
• Biofuels

Solar Energy

Solar energy is the energy that is produced by the sun’s radiation. Then, it will be going to convert into thermal or electrical energy from several technologies. There are widely used solar technologies like as photovoltaics (PV) that is directly converted sunlight into electricity. Solar thermal systems use the sunlight for generating the heat for producing electricity. Therefore, Solar energy is a most powerful and abundant renewable energy source along with the potential to meet all future energy requirements.

Wind Energy

Wind energy is also come into a renewable energy that is getting to harness the power of the wind to produce the electricity. This technology is going to use wind turbines to convert the kinetic energy for moving air into electrical energy. Wind power is considered a sustainable and clean energy source, with a much smaller environmental impact compared to burning fossil fuels.

The global installed wind generation capacity has increased significantly since 2000, driven by research and development, supportive policies, and falling costs.

Hydroelectric Power

Hydroelectric power is also known as hydroelectricity that uses the power of moving water to generate electricity. Hydropower supplies one-sixth of the world’s electricity, more than all other renewable sources combined, and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems.

Most hydroelectric power comes from the potential energy of dammed water driving a water turbine, and the power extracted from the water depends on the volume and on the difference in height between the water source and the turbine. A large pipe delivers water from the reservoir to the turbine.

Geothermal Energy

Geothermal energy is heat energy that is going to produce by the Earth’s crust that is arisen from the planet’s formation and the decay of radioactive raw materials. It has been used for millennia along with applications, like as heating and electricity generation.

Geothermal resources are reservoirs of hot water and steam that is tapped for several objectives, including the electricity generation, direct use, and heating and cooling. Geothermal energy is a renewable, low-carbon energy source that is continuously replenished by the Earth’s internal heat.

Biomass Energy

Biomass energy is derived from organic materials such as plants, wood, and waste. These materials, known as biomass feedstocks that can be burned to create heat, converted into electricity, or processed into biofuels. Biomass is considered a renewable energy source as it can regrow in a relatively short amount of time, and it is a clean energy source, as its initial energy comes from the sun.

Biomass energy is going to use for centuries; and it gets to continue to be an important fuel for several applications, like as heating, transportation, and electricity generation. In 2022, biomass provided nearly 5% of total primary energy use in the United States, with sources including wood, agricultural crops, and waste materials

Tidal Energy

Tidal energy is a form of power that is derived from the natural rise and fall of tides caused by the gravitational interaction between Earth, the sun, and the moon. It is a renewable and predictable energy source, as tides are influenced by the moon and sun’s positions, and their energy potential is relatively constant. Tidal energy can be converted into useful forms of power, including electricity, using specially engineered generators in suitable locations.

Hydrogen Energy

Hydrogen is purified and versatile energy carrier that is generated by the various domestic resources, including natural gas, biomass, nuclear power, and renewable power such as solar and wind. It is the essential abundant chemical element that is estimated to contribute 75% of the mass of the universe. Hydrogen is also going to use for a fuel in several applications, such as electricity generation and transportation.

Biofuels Energy

Biofuels are liquid fuels that are generated by renewable biological sources, including plants and algae. They facilitate the solution to the challenge of replacing liquid fuels, including the jet fuel, gasoline, and diesel fuel. Biofuels can be converted directly into liquid fuels, called “biofuels,” to help meet transportation fuel needs.

The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology. Ethanol is produced by fermenting sugars from crops such as corn and sugarcane, while biodiesel is produced from vegetable oils and animal fats.

Renewable Energy for Home

Here are several options for incorporating renewable energy into your home:

Solar Panels

Photovoltaic (PV) Systems: Solar panels convert sunlight into electricity. Install solar panels on your roof or in your yard to generate electricity for your home. You can also consider solar shingles that blend into your roof.

Solar Water Heaters: These systems use the sun’s energy to heat water for domestic use or space heating. They are particularly effective in sunny climates.

Wind Turbines

Small-Scale Wind Turbines: If you have enough open space and live in an area with consistent wind, a small wind turbine can generate electricity for your home. Ensure proper zoning regulations and wind conditions before installation.

Hydropower

Micro-Hydro Systems: If you have access to a flowing water source, a micro-hydro system can generate electricity. This is more suitable for rural areas with a reliable water supply.

Geothermal Systems

Geothermal Heat Pumps: These systems use the constant temperature of the ground to heat or cool your home. They are highly efficient and have lower operating costs compared to traditional heating and cooling systems.

Biomass Energy

Biomass Boilers: Use organic materials like wood pellets, agricultural residues, or other biomass sources to generate heat for your home. Biomass can also be used for combined heat and power (CHP) systems.

Energy Storage

Battery Storage: Invest in battery systems to store excess energy generated by your renewable sources. This allows you to use the stored energy during times when the renewable source is not producing electricity.
