What is clean energy?

In light of the climate emergency and the energy crisis threatening the planet, we have a duty to find solutions and implement policies and measures to deal with these problems. One highly effective, efficient way to do this is by investing in clean energy, as we will explain in detail later on.

DEFINITION OF CLEAN ENERGY

Clean energy comes from generation systems that do not produce any kind of pollution, notably greenhouse gases like Co2, which cause climate change. Therefore, clean energy – in full development – drives advances to conserve the environment and palliate the crisis with non-renewable fuels, such as gas and oil. 

DIFFERENCES BETWEEN CLEAN AND RENEWABLE ENERGY SOURCES 

Clean energy and renewable energy are two concepts that are bundled together, but they are not the same thing and it is important to understand the difference. The first difference is the pollution they cause. You may not realize that renewable energies can cause pollution.

For example, biogas and biodiesel are renewable sources of energy because, among other things, they come from natural, inexhaustible sources. However, unlike most renewable energies, they pollute the atmosphere on combustion, emitting greenhouse gases.

Clean energies do not pollute and, therefore, it is fair to say that most renewable sources of energy are also clean and vice versa.

THE MOST COMMON TYPES OF CLEAN ENERGY AND HOW THEY WORK 

Most clean energy is also renewable and therefore, in addition to nuclear energy – which we will address later on – the following are currently the most common:

Wind energy

It is a clean, renewable, local, inexhaustible source of energy obtained by transforming the kinetic energy from the wind into electricity. There are two types, according to where the wind turbines are installed:

• Onshore wind energy: it uses

  currents of air produced on land

  .

• Offshore wind energy: It uses the

  wind that blows on the high seas

  , where they reach higher speeds and are more constant.
