The seriousness and urgency of tackling climate change require a rapid transition to the massive use of renewable energies. Emerging and developing economies are increasingly using hydroelectric power, wind power, bioenergy, solar energy and geothermal energy in the global power mix.

A global energy transformation is necessary to ensure the survival of the planet. There is progress all over the world, but at different rates.

Asia increased its installed renewable energy capacity by 11.4% and 61% of new solar installations in 2018.

Oceania ranked second, adding 17.7% of green power capacity. The third place is occupied by Africa, with a growth of 8.4%.

Despite the achievements, there is still a long way to go for a real decarbonization of the economy, according to the study carried out by the International Renewable Energy Agency (IRENA), an organization that produces the most recent statistics on renewable energies.

The analysis compares renewable energy to non-renewable energy, particularly in the use of fossil fuels and nuclear energy. Asia and the Middle East saw growth in non-renewable generation of around 115 GW.

Advance of renewable energies.

Renewable energy production capacity reached 2351 GW in 2018. Its main sources are as follows:

Bioenergy or biomass.

Its levels remain low. China increased its capacity by 26 GW, India by 700 MW and the UK by 900 MW.

Solar energy.

Asia dominated global growth with an increase of 64 GW, which constitutes 70% of the world total in 2018. The list is followed by the United States (8.4 GW), Australia (3.8 GW) and Germany (3.6 GW).

Geothermal energy.

Turkey leads geothermal energy development with 219 MW, followed by Indonesia with 137 MW. New Zealand, Mexico and the United States have also added capacity with this energy model, but at modest levels compared to other generation technologies.

Hydroelectric.

They were installed approximately 1172 GW. Only China added significant capacity, estimated at 8.5 GW.

Wind.

He contributed 53 GW. The United States and China are the most invested countries. Other countries like Germany, Brazil, France, India and the United Kingdom increased by more than 1 GW respectively.

The growth of renewables in 2018 mirrored the trends of the past five years, meaning that clean energy models take precedence throughout the world. Will this be enough?
