What subsidies are available to fund the energy transition?

The Spanish government is offering households and businesses a range of subsidies for renewable energy, energy efficiency, and sustainable mobility projects.

Geothermal energy, the natural energy of the Earth
The heat generated from the Earth's interior is an energy source with great potential that can greatly benefit areas such as electricity production or air conditioning.Geothermal energy is a primary energy source that harnesses the Earth's heat, and thanks to its sustainable characteristics, it could be key in steadily making headway in decarbonizing energy for the future. It is a renewable, clean, and inexhaustible alternative that needs to be promoted as it could offer great security to the energy market when times get as difficult as they are currently. Many countries, including ours, have great geothermal capacity in their soil, just waiting to be exploited. It is essential to encourage its use at all levels, both in air conditioning and electricity supply. Even more so, bearing in mind all the advantages it could bring in the short term, in terms of efficiency and emissions reduction. What is geothermal energy? Geothermal energy is the use of heat energy that emanates naturally from the Earth’s core. To fully understand how this energy works, it is important to know that the Earth's interior is divided into different layers. The crust is the outer layer where all we all live, then there is the intermediate area called the mantle and, finally, the deepest area of the Earth is the core. This last layer is formed by minerals, mainly iron, and its main characteristic is that it is at a constant extreme temperature of around 6,000°C, similar to that of the sun. The core’s high temperatures are transmitted residually upwards through the other layers, until they reach the crust. Here, in this outermost layer, and through a series of excavations of the subsoil at different depths, we can access the natural heat coming from the core and convert it into energy using technology. Benefits of geothermal energy The heat energy generated at the Earth's interior has a number of unique characteristics that make geothermal energy one of the most advantageous renewable primary sources. Continuous production. It is an inexhaustible resource that is active 24 hours a day, all year round.. Highly stable. It does not depend on external factors such as the weather, unlike the sun and wind. Low impact. Its installations have a low visual and noise impact and take up little space. Extremely efficient. It is one of the cheapest renewable energies and with the most capacity for use. Sustainable. Committing to this natural energy would help considerably in reducing greenhouse gas (GHG) emissions. It has huge benefits for the energy transition, but which are relatively unknown to the general public, as pointed out by the president of RHC-ETIP (Geothermal Panel of the European Technology and Innovation Platform on Renewable Heating & Cooling), which has consequences when it comes to promoting its expansion. Geothermal resources: types and uses Taking into account temperature and enthalpy, the thermodynamic magnitude that measures the energy obtained from each reservoir, conventional geothermal energy can be divided into four different types:
The problem of deforestation in the fight against climate change
The forests that populate our planet play a crucial role in naturally and effectively reducing CO2 emissions in the atmosphere.Nearly one third of the Earth's surface is covered by different types of forests and, because of the important role they play within the ecosystem, protecting them properly is more important than ever. They are essential natural environments, not only for biodiversity development, but they are also important due to their role as natural carbon reservoirs and sinks at a time when greenhouse gas (GHG) emissions are still very high. The problem we are currently facing with forest cover at the international level is that it has been decreasing over the years, mainly due to external agents related to human action, such as deforestation or degradation. These activities have put their preservation in jeopardy and could lead to fatal consequences in the fight against climate change if they continue in this way.  The role of forests Forests are indispensable players in the battle against the climate crisis, due to their ability to absorb CO2 from the atmosphere. So if they disappear, this carbon would remain in the atmosphere. Like all other plants, algae, and a wide variety of bacteria, trees perform photosynthesis. In this biochemical process, they convert the CO2 they absorb from the atmosphere, as well as the water and sunlight they take in through their leaves and roots, into molecules of glucose and other sugars needed for their survival. As forests are large tracts of land where a large number of trees and plants coexist and carry out this process on a regular basis, a sink is created in the area where this natural process considerably reduces the level of carbon dioxide in the air. The type of photosynthesis performed by the trees is called oxygenic and has the particularity that, in addition to capturing carbon dioxide, it also releases oxygen during conversion. Thus, trees are not only responsible for the important task of reducing CO2, but they also generate a large part of the oxygen necessary for the well-being of all living things.
