With sustainable living rising in popularity, it's no surprise that lots of households are turning to green energy when it comes to their gas and electricity. We break down the clouds surrounding green energy and show you how you can “go green” for the sake of the planet.

What is green energy?

Green energy comes from natural sources such as the sun, wind and water, which are 100% renewable and therefore, better and “greener” for the environment.

Green and renewable energy are often used interchangeably but there’s a subtle difference. All green energy is renewable energy but not all renewable energy is green energy.

Renewable energy can come from other sources like wood, ethanol and biodiesel, which aren’t clean sources of energy and thus, not “green” as they contribute to climate change.

Where does green energy come from?

As well as solar and wind power, green energy can also come from a number of different sources. While the names may vary, depending to who you ask, the methods of generating the energy consistently come from:

  • Hydropower - energy created from strong underwater currents

  • Tidal power - like hydropower but using the twice-daily tidal currents to drive turbine generators

  • Geothermal sources - electricity that comes from the earth’s natural heat

  • Hydrogen - combined with oxygen to produce electrolytes (electrical charges)

  • Biomass - heat energy source from organic materials such as animal or plant matter.

Is green energy more expensive?

The answer is both yes and no. The average green energy tariff tends to be cheaper than most standard variable tariffs (SVTs). And this shouldn't come as a surprise as SVTs are usually the most expensive tariffs on the market.

You can produce your own green energy at home using solar panels, i.e. Solar Power to create electricity and hot water or, wind turbines from wind energy to create electricity. The initial investment in creating your own green energy can be steep but in the long run, you could see big savings on your energy bills.

To help lower the cost of installing green energy appliances, there aregovernment energy grants that can help you going green. Other schemes include Feed-in Tariffs (FiT), in which you feed energy you’ve produced back into the National Grid and the government compensates you for it.
