FAQs about Solar Energy

2. Is solar energy a clean or green source?

Photovoltaic energy does not emit any type of pollution or waste during its operation, so it does not produce greenhouse gases. Therefore, it is a clean, green and renewable energy since it meets the definition of these: a non-polluting energy production system that does not produce waste. It is renewable because the sun is an inexhaustible source of energy.

A photovoltaic park can operate for several decades with a minimum of maintenance. Upon reaching the terms of its useful life, photovoltaic panels can be recycled and recovered up to 95%, so they do not become garbage or scrap. In the European Union there are some private non-profit organizations that are responsible for collecting and recycling panels at the end of their useful life.

Solar energy, a big bet against climate change

Solar energy is one that uses light or heat from the sun to generate electricity or produce heat. Photovoltaic solar panels convert sunlight into electricity through a process called photoelectric. There are millions of people who already use electricity generated by solar energy. The world is aware of the importance of the transition towards a sustainable economy, based on low greenhouse gas emissions to curb global warming and therefore climate change. However, there is still a long way to go to significantly reduce the use of fossil fuels such as coal, gas and oil…


Solar energy, a clean, inexpensive and inexhaustible source

Solar energy along with wind energy and electric cars, forms a powerful trio to face global warming and climate change. Solar energy is in direct line with the Paris Agreement, based on the non-emission of greenhouse gases and the replacement of fossil fuels with clean energies.
