Geothermal Energy

Geothermal energy is a renewable energy source that could make a big difference to the home and Earth's way of generating power. Geothermal power plants emit about 97% less carbon dioxide (CO₂) per unit of electricity generated compared to fossil fuel-based power plants. Geothermal energy works by tapping into the Earth's natural heat, just like turning on a tap to get hot water. Special systems use pipes buried underground to capture that heat and bring it up to your home. Then, it's used to warm your house in the winter and cool it in the summer, all without burning fossil fuels.

Geothermal energy installations can cost $10k-40k USD, but after the installation costs, the average kWh costs 5-9 cents USD. Using the national average family usage of 12,000 kWh annually, the yearly cost after installation fees comes out to $600-$1,080. Additionally, in The United States, to offset the high installation costs, homeowners may qualify for the Federal Residential Renewable Energy Tax Credit, which offers a tax credit of up to 26% of the cost of various geothermal pumps. Additionally, some states or local utilities may offer their own incentives, such as rebates or grants, to encourage the adoption of geothermal energy systems.
