What is the definition of green energy?
Green energy is energy that can be produced using a method, and from a source, that causes no harm to the natural environment.
What is green energy?
And what’s the difference between green energy, renewable energy and clean energy? Often these terms are used interchangeably, but there are some differences.One thing that green, clean and renewable energy all have in common is that they're being increasingly used to generate electricity in order to phase out the use of fossil fuels, like coal and gas, which are a key cause of climate change.
What’s the difference between green energy and renewable energy?
The terms ‘green energy’ and ‘renewable energy’ are often used interchangeably, but there is one essential (and sometimes confusing) difference between them. While most green energy sources are also renewable, not all renewable energy sources are considered entirely green.
Renewable energy comes from sources that are constantly and naturally renewed (hence the name), such as wind power and solar power. Renewable energy is also often called sustainable energy.
A renewable energy source may not be considered ‘green’ if, for example, some carbon emissions are associated with the processes used to generate the energy – such as the building of infrastructure.
What's the differences between green energy and clean energy?
Clean energy is energy that, when used, creates little or no greenhouse gas emissions.
As with renewable energy, some types of clean energy may not always be considered entirely green.
How Does it Work?
As a source of energy, green energy often comes from renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power. Each of these technologies works in different ways, whether that is by taking power from the sun, as with solar panels, or using wind turbines or the flow of water to generate energy.
What Does it Mean?
In order to be deemed green energy, a resource cannot produce pollution, such as is found with fossil fuels. This means that not all sources used by the renewable energy industry are green. For example, power generation that burns organic material from sustainable forests may be renewable, but it is not necessarily green, due to the CO2 produced by the burning process itself.
Green energy sources are usually naturally replenished, as opposed to fossil fuel sources like natural gas or coal, which can take millions of years to develop. Green sources also often avoid mining or drilling operations that can be damaging to eco-systems.
