What is renewable energy?

Currently, most power in the United States is generated by burning fossil fuels such as coal, oil, and natural gas in large central power plants. Combusting these "nonrenewable" fuels pollutes the air and releases harmful greenhouse gases.

What is renewable energy

By contrast, resources such as wind and sunlight are "renewable" - they are easily retrieved, naturally replenished, and do not harm the environment when used to generate power. Solar energy systems have been in use for decades, and wind and water have been used to generate power for centuries.

Why consider renewable energy for my home or business?

As demand for power rises and utilities struggle to meet this demand, power from the public utility grid becomes more expensive and less reliable. An ideal solution to this problem, independent power generation systems using renewable energy sources are…

Affordable and cost-effective. Government rebate plans for homeowners and businesses cover up to 50 percent of renewable energy system costs, enabling systems to pay for themselves in two to three years. And, because utility companies are required by federal law to purchase your excess power, you can watch your electric meter run backward.

Reliable. Homes and businesses that generate power independently can receive an adequate, reliable supply of high-quality power that is not subject to utility companies' scheduled and unscheduled blackouts. And, by remaining connected and synchronized to the power grid, the utility provides you backup power during routine maintenance or other service procedures.

Environmentally friendly. Using renewable resources for power generation decreases air pollution. For example, a 3-kW system avoids release of about four tons of carbon dioxide (a greenhouse gas) into the atmosphere-the equivalent of driving the average passenger car about 100000 miles.

Types of Renewable Energy

There are many types of renewable energy available all around the world.

1. Hydroelectric energy

The power that utilized flowing water to create electricity is called Hydro power.

2. Bio energy

The energy that is created from plants or grains can be replenished and replanted known as bio energy. An example of using bioenergy is ethanol.

3. Wind energy

Wind energy was probably the first type of renewable and natural energy that was used to provide power. Wind energy is mainly used for supplying electricity locally like on and around wind farms. Although wind energy is not yet widely used in the United States, the United States is third on the list of countries that have the most capacity to produce wind energy. There is a limit to how much energy wind can produce since wind can’t be grown like the crops that are used for bioenergy, and the wind is not as constant as the water used to create geothermal or hydro energy.

4. Geothermal energy

The power which comes from using the natural heat from deep inside the earth is Geothermal power. It is less than 1% of all the electricity produced in the United States is generated from geothermal energy, but the United States is the biggest user of geothermal energy for electricity in the world.

5. Solar energy

Solar energy is using the energy generated by the sun for things like heating and electricity. Now it is used mainly to create electricity and create heat.

There are two ways to use solar energy to generate electricity. The use of Photovoltaic is the first method. The sun’s energy is collected and converted into electricity by using a collection of cells made of certain materials. Another way is using solar power plants. These huge plants indirectly create electricity by using sunlight.

Is renewable energy right for me?

It is now simple and affordable to harness the abundant power of the sun and wind to provide homes and businesses with cost-effective, environmentally friendly electricity. Solar- and wind-powered energy systems are fueled by non-polluting renewable resources that cost nothing to obtain. By adding a renewable electric system to your home or business, you reduce the amount of electricity that you purchase from your power company, which reduces your monthly bill.
