Types of Renewable

Biofuels
Biofuels

The two most common types of biofuels are ethanol and biodiesel. Ethanol is an alcohol, the same found in beer and wine. It is made by fermenting any biomass high in carbohydrates (starches, sugars, or celluloses) through a process similar to brewing beer.

Biomass
Biomass

What is Biomass? Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power. Some examples of materials that make up biomass fuels are: scrap lumber; forest debris; certain crops; manure; and; some types of waste residues.

Coal
Coal

What is coal? Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. Coal is made of the remains of ancient trees and plants that grew in great swampy jungles in warm, moist climates hundreds of millions of years ago.

Fossil Fuels
Fossil Fuels

Fossil fuels - non-renewable. In 2011 fossil fuels made up 83% of the world’s energy use. These are resources found under the ground: coal, oil and gas. In 2020 this is predicted to decrease to 76% as nuclear power, and in particular, renewable energy use increase. See World Energy (PDF) for more information.

Geothermal
Geothermal

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system.

Hydroelectric Energy
Hydroelectric Energy

Turbines and generators capture and convert that energy into electricity, which is then fed into the electrical grid. The water itself is not reduced or used up in the process, and because it is an endless, constantly recharging system, hydropower is defined as a renewable energy by the Environmental Protection Agency.

Hydroelectric Power
Hydroelectric Power

For a power source that is clean and renewable—it doesn’t pollute the air because no fuels are burned and it’s renewable because it uses the Earth’s water cycle to generate electricity—one would think hydropower would get as much attention and investment as other noncarbon sources of energy.

Natural gas
Natural gas

Renewable Natural Gas (RNG), also known as Sustainable Natural Gas (SNG) or biomethane, is a biogas which has been upgraded to a quality similar to fossil natural gas and having a methane concentration of 90% or greater. A biogas is a gaseous form of methane obtained from biomass.

non-Renewable Energy
non-Renewable Energy

Renewable energy includes solar, hydro and wind energy. Wind energy is made when the wind moves the blades on a wind turbine. This movement creates wind energy which is converted into electrical energy.

Nuclear Energy
Nuclear Energy

Although nuclear energy is considered clean energy its inclusion in the renewable energy list is a subject of major debate. To understand the debate we need to understand the definition of renewable energy and nuclear energy first.

Other Forms of Energy
Other Forms of Energy

Compared to other forms of renewable energy, wind power is considered very reliable and steady, as wind is consistent from year to year and does not diminish during peak hours of demand. Initially, the construction of wind farms was a costly venture.

Petroleum
Petroleum

What is Petroleum (Crude Oil)? Crude oil (a non-renewable resource) is usually found in underground areas called reservoirs. It is liquid in nature and yellowish black in color. They are composed mainly of hydrocarbons and organic compounds. They are usually discovered by oil prospecting scientists.

Solar
Solar

Solar panels converts the sun's light in to usable solar energy using N-type and P-type semiconductor material. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity.

Solar Power
Solar Power

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery. A Swiss scientist, Horace de Saussure, built the first thermal solar collector in 1767, which was later used to heat water and cook food.

There are Many Forms of Renewable Energy
There are Many Forms of Renewable Energy

The world’s energy needs could be reduced by one-third by 2050 if individuals and corporations work to save energy now and begin relying on renewable energy sources provided by power companies and personalized adoption. Renewable energy allows you to tap into natural resources that are replenished as part of the normal life cycle.

Wind Power
Wind Power

Today, the windmill's modern equivalent - a wind turbine - can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.
