The Use of Geothermal Energy in Renewable Energy Projects

Around the world, geothermal energy is used for heating and cooling, electricity generation, and other applications. With significant advancements in technology, opportunities for geothermal energy have increased in recent years. However, scaling geothermal energy to be widely used in renewable energy projects faces many barriers and opportunities that must be addressed by governments, policymakers, and investors.

What is geothermal energy?

Geothermal energy is the energy generated from heat stored in the earth’s core, near-surface rocks, and hot water. Geothermal energy has many benefits compared to other sources of energy, including:

  • Zero greenhouse gas emissions
  • A reliable source of energy that can operate 24/7
  • Long-term stability, as it is not affected by weather or seasonal changes

The Barriers of Scaling Geothermal Energy

Despite the many benefits of geothermal energy, it remains underused in renewable energy projects. This is in part due to several barriers that make it challenging to scale up geothermal energy. The major barriers are:

High Initial Costs

One of the biggest obstacles standing in the way of scaling geothermal energy is the high initial costs. The cost of drilling, testing, and setting up a geothermal power plant is significant, making it harder for investors to consider geothermal energy as a long-term renewable energy solution.

Limited Access to Geothermal Resources

Another barrier to scaling geothermal energy is the limited access to geothermal resources. Hot springs and geysers are the most well-known signs of geothermal heat, but they are rare and often not located near areas with significant energy demand. This means that significant investments must be made to locate and develop geothermal resources.

Potential Environmental Issues

Geothermal drilling can cause potential environmental issues, including land subsidence, greenhouse gas emissions, and the release of hazardous chemicals. These environmental issues make the cost of geothermal energy more expensive due to the added cost of environmental regulations and cleanup efforts.

Opportunities to Scale Geothermal Energy

Despite the barriers, there are numerous opportunities to scale up geothermal energy in renewable energy projects.

Technological Advancements

With advances in geothermal drilling and energy conversion technologies, the cost of geothermal energy is continually decreasing. These advancements allow for a faster return on investment for geothermal projects, making it a more viable option for long-term energy solutions.

Co-located Projects

Co-located renewable energy projects, such as those that combine wind or solar with geothermal energy, can increase the value proposition of renewable energy projects. These integrated projects can supply the energy needed to heat, cool, and power homes and businesses, thereby reducing overall energy costs.

Environmental Benefits

Geothermal energy is one of the cleanest forms of renewable energy, with zero emissions and a small environmental footprint. This makes it an attractive option for those looking to reduce carbon emissions and mitigate the effects of climate change.

Energy Independence

Geothermal energy provides a long-term, stable source of energy, allowing countries to become more energy independent. When coupled with energy storage systems, geothermal energy can provide non-stop baseload power for communities and industrial plants.


Scaling up geothermal energy in renewable energy projects is necessary to reduce carbon emissions, mitigate climate change, and achieve energy independence. Governments, policymakers, and investors must put more effort and investment into scaling up geothermal energy by addressing the barriers and promoting opportunities that can make geothermal energy a viable solution. With technological advancements, co-located projects, and environmental benefits, geothermal energy has the potential to become a major player in the renewable energy market.
