Renewable energy is defined as energy produced from natural resources such as sunlight, wind, rain, tides, and geothermal heat.
Lisa Juan José Gutiérrez Mayorga explains in other words, renewable energy is known as energy created by natural processes that are constantly renewed. This includes solar energy, geothermal heat, wind, tides, water, and various types of biomass. This energy never runs out and is constantly replenished.
The term alternative energy is used for a source of energy that is an alternative to the use of fossil fuels. Generally, it indicates non-traditional energies with low environmental impact. The term alternative is used to contrast with fossil fuels, according to some sources. According to most definitions, renewable energy is environmentally friendly, a distinction that separates it from renewable energy that may or may not have a significant environmental impact.
What is biomass?
Biomass is a renewable energy material and can include biological material derived from living or recently living organisms, such as wood, waste, and alcoholic fuels.
Wood energy is obtained both from wood harvested for fuel and from wood waste products. Waste energy can be generated from municipal waste, manufacturing waste, and landfill gas. Biomass alcohol fuel, or ethanol, is derived almost exclusively from corn.
What is biodiesel?
Biodiesel is a fuel made from vegetable oils that can be used in diesel engines. They are usually made from renewable organic raw materials, such as soybean or rapeseed oils, animal fats, waste vegetable oils or oils from microalgae.
5 main types of renewable energy
Whether it’s for your home, business, or community, there’s never been a better—or cheaper—time to switch to renewable energy for all of your power needs. At stake is the future habitability of the planet, propitiated by the elimination of carbon emissions that allow renewable energies.
What form of energy is the cheapest ever to produce the electricity on which almost everything in modern life depends?
Answer: Solar energy, a leading type of renewable energy.
For the first time, according to the International Energy Agency (IEA), in its World Energy Outlook 2020 published in October 2020, renewable solar energy is the “new king”, beating non-renewable coal at its own game.
In fact, solar power has outperformed IEA predictions made last year by 20-50% (although the range varies by location). Onshore and offshore wind projects also enjoyed similarly large cost reductions from previous estimates, also surprising naysayers.
Solar and wind power represent just two of several types of renewable energy. Here you’ll discover tons of clean energy facts and statistics about the top forms of renewable energy, including how one or more fits into your home, business, or community.
Making the switch to renewable energy will not only save you money. It will reduce the carbon footprint. As our climate crisis intensifies, a clean energy transformation will help curb negative outcomes for people and the planet.
