A renewable energy source means energy that is sustainable - something that cant run out, or is endless, like the sun. When you hear the term alternative energy its usually referring to renewable energy sources too. It means sources of energy that are alternative to the most commonly used non-sustainable sources like coal.
Sunlight is one of our planets most abundant and freely available energy resources. The amount of solar energy that reaches the earths surface in one hour is more than the planets total energy requirements for a whole year. Although it sounds like a perfect renewable energy source, the amount of solar energy we can use varies according to the time of day and the season of the year as well as geographical location. In the UK, solar energy is an increasingly popular way to supplement energy usage.
The most popular method of harvesting sunlight is through solar Farms. They play a huge role in global renewable energy projects and are vital to ensure every continent is working towards a carbon neutral goal.
Even the land used by solar farms is a safe place that natural wildlife can flourish and causes 0 negative impact on the environment.
Because they require no fuel, wind farms have less impact on the environment than many other forms of power generation.
Wind farms have, can be located onshore or offshore and typically have a very low impact on the environment. Wind farms have become another very essential tool to create renewable energy.
Waste energy is not as well explored as wind farms and solar farms but will pay a kep part in the future of renewables.
Many governments are aligned with their aims of reducing waste and this process prevents waste heading to landfill and being converted into energy to put back into the power grid.
