We can safely say that the industrial development of previous centuries was not forged on a firm basis of energy efficiency. It is now that we are facing the dilemmas regarding how we will be able to respond to increasing urban energy demands.Buildings, the most significant and iconic features of any city, are literally devouring urban energy. In the European Union, 40% of energy consumption (and 36% of carbon dioxide emissions) come from basic services including heating, cooling and hot water in buildings. This is why the energy sector is constantly looking for alternatives to alleviate this consumption, with smarterbuildings and sources of energy.
What is geothermal energy?We must remember that 81% of that energy comes from coal and oil combustion. One of the solutions gaining popularity with institutions is geothermal energy. The technology associated with this renewable source of energy production seeks to use the Earth’s internal heat to replace fossil fuels.European legislation in Directive 2009/28/EC offers us the best and simplest of definitions:
Geothermal energy means energy stored in the form of heat beneath the surface of solid earth.It involves using the flow of heat that exists within the earth’s crust. There are three systems: using hot springs, dry springs or even geysers. Depending on the location, more or less energy can be obtained. The geology offered by countries such as Iceland, Italy or New Zealand makes them ideal for installing geothermal plants.
