Renewable Energy Heating Systems

Renewable energy utilises the earth’s natural resources such as the sun, wind, rain, tides, waves and geothermal heat.

These natural resources can be used to generate energy, which is sustainable and naturally replenished. Energy consumption levels cannot be sustained from the supply of gas and oil and so renewable sources need to be identified and harvested.

Renewable energy systems, combined with conventional heating equipment, provide an efficient way to address this issue and reduce your environmental impact from harmful carbon emissions.

How sustainable is renewable energy?

That’s a question we are asked a lot by our customers. The answer is very! As the name suggests, renewable energy is totally sustainable, as it comes from resources that can easily be replenished – unlike fossil fuels such as coal, oil, and gas.

What renewable energy sources are available today? Well, some good examples are: solar energy from the sun; geothermal energy that is generated from heat inside the earth; wind energy; biomass from plants; and hydropower that comes from flowing water.

Each have their own unique benefits, and the team here at Terra Therma would be happy to talk you through all of them. Just contact us today, and we will answer all of your questions.

Renewable energy has a wide range of benefits, the most obvious of which is that it has much less impact on the planet. There are none of the greenhouse gas emissions you get from fossil fuels and many types of air pollution are also reduced. It also helps to diversify the energy supply, which means less reliance on imported fuels.

There are a number of grants and incentives to encourage property owners across the UK to make the switch to renewable energy. If you want to find out more about those grants and funding for renewables, we have provided all the information you need – and would be happy to answer any further questions.
