Clean and Sustainable Energy -

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.

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:. 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.

Hydroelectric energy is a clean, renewable, emissions-free, local source of power that uses the force of water falling from a height or running down a slope to produce electricity.

This type of power generation can be divided into hydroelectric pumping stations , the most efficient, large-scale energy storage method in existence. Energy storage, in addition to integrating renewables, brings efficiency savings to the electrical grid.

Green hydrogen is based on generating hydrogen, a universal, light and highly reactive fuel , using a chemical process known as electrolysis. This method uses an electric current to separate the hydrogen from the oxygen in water, so if this electricity is obtained from renewable sources, we will produce energy without emitting carbon dioxide into the atmosphere.

It is a source of clean, renewable energy that produces electricity by burning natural organic material or organic waste produced by human activity. It is a type of clean, renewable and inexhaustible energy that harnesses the heat that radiates from the center of the Earth using power plants located on deposits.

These may be hot water deposits, in which case the heat comes from layers of hot water flowing beneath the surface, or dry, which uses heat from rocks.

It is a source of clean, renewable, local and inexhaustible generation that converts the power of waves into electricity. Other types of renewable energy include solar thermal energy , which uses the heat of the sun, wave energy , which converts the energy from waves, and ocean thermal energy conversion, which uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawater.

As well as these, more and more hybrid energy projects are emerging that combine different renewable generation sources to ensure a more stable, efficient supply. Despite what many people think, nuclear energy is clean throughout its generation, as well as being almost inexhaustible using current uranium reserves, which will be able to continue producing the same quantity of energy for thousands of years.

In fact, most nuclear reactors only emit water vapour into the atmosphere. Neither CO2, nor methane, nor any other type of polluting gas that aggravates climate change is part of the equation. What's more, we must not forget the enormous amount of energy a single power station can generate because of the massive power stored in nuclear energy.

This energy is obtained in two ways: nuclear fusion and fission. In the first of these, energy is released when the nuclei of atoms combine or fuse together to create a larger nucleus. In the second, the nuclei separate to form smaller ones and, in turn, release energy.

As you can see, there are numerous types of renewable energy, but what do they all have in common? They are environmentally friendly : no clean energies generate greenhouse gases or other polluting emissions into the atmosphere.

They are unlimited: we obtain them from inexhaustible or rapidly regenerating natural resources , so they can be used indefinitely and without limit. They promote energy independence : because they use natural resources found all over the planet, so that countries and regions are able to develop their own technologies rather than depending on electricity produced abroad.

They create jobs and boost the local economy : most renewable facilities are labour-intensive to build, maintain and operate, which creates jobs and stimulates the national economy. The United Nations predicts that the world population could reach 8.

Two-thirds of them live in cities and living standards are improving as emerging countries join the global middle class. All this means a higher worldwide demand for energy , which could increase according to the most recent report issued by the U.

Energy Information Administration EIA. Fossil fuels cannot satisfy this demand. Firstly, because it is estimated that oil reserves will be exhausted within 40 to 50 years and natural gas, within 60 to 80 years.

Secondly, because fossil fuel combustion releases greenhouse gas emissions into the atmosphere, causing global warming and climate change , the main menaces to humanity in the 21st century. In such a scenario, it is crucial to opt for safer, more plentiful and less environmentally damaging sources of energy.

Solar PV alone accounted for more than half of new renewable energy installations with a record GW, followed by 93 GW of wind power overall, 21 of which are offshore wind installations.

At the Iberdrola group, we are a world leader in renewable energies , in addition to being leaders in installed renewable capacity. These energies are the fundamental pillar on which our clean, reliable and intelligent business model is built.

Thanks to our investment plan - extended to - we aim to double this renewable capacity to 60 GW in , while reaching 95 GW in One of the main keys to the group's future growth is offshore wind , which is the second most important technology thanks to the strong growth experienced in the last year.

Our goal is to consolidate our position as a global benchmark in offshore wind, and thanks to the expansion of our offshore wind portfolio, we are in an unbeatable position to participate in auctions and tenders that arise, both for existing projects and for new opportunities.
