Geothermal energy is heat taken from the earth's core and turned into renewable energy that can heat your home.
The above definition is just a small proportion of what geothermal energy is. Here are 6 interesting facts about geothermal energy:
1. The first use of geothermal energy
Evidence suggests that geothermal isn’t a new discovery. In fact, it’s been noted that the earliest use of geothermal energy was at least 10,000 years ago in North America. It’s thought that indigenous people used hot springs for practical use.
The amount of geothermal energy resources readily available depends on the location. The UK, for example, is not traditionally the best place for geothermal energy. However, with the help of ground source heat pumps, UK homes can now extract this energy and take advantage of this renewable heating source.
2. How geothermal is used today
In 1986 Southhampton City Council opened a geothermal power station that provides heating to the city hall, supermarket, swimming centre, 300 flats and surrounding hotels.
Ground source heat pumps are the only geothermal energy source used domestically. These heat pumps can heat radiators, underfloor heating and water.
3. Affordable heating
As of Spring 2022, energy bills have increased by a massive 54%. By switching to renewable heating systems such as geothermal underground heat pumps or air source heat pumps, homeowners could save money on their monthly bills.
The initial upfront payment of heat pumps can be expensive. However, with the government's boiler upgrade scheme, homeowners could get up to £5000 off the initial cost.
4. The greek meaning of geothermal
The word geothermal originates from 2 Greek words, “geo”, meaning earth and “thermal”, meaning heat.
5. A booming geothermal market
In 2020, the geothermal energy market size was estimated to be $52.87 billion (approximately £45 billion), which in 2028 is expected to reach $83 billion (£63 billion). However, the growth of the geothermal market may slow down due to the repercussions of the pandemic.
Iceland currently has the largest share of the geothermal market. Iceland's electricity comes from almost 100% renewable energy, utilising its hydropower and geothermal resources.
6. Used for heating and cooling
When thinking of geothermal energy, many people instantly think of heat (especially in the UK). But these heat pumps can also be used as a cooling system in warmer months.
Put simply, the heat transfer process works in reverse. As the warmer air circulates your home, the heat pump removes the warm air and transfers it to the ground due to the lower temperature.
Ground source heat pumps are one of the most efficient renewable energy systems.
