The transition to renewable energies is essential for the survival of the planet. Here are a number of key factors behind it.
The Paris Agreement proposes a climate policy common to ensure the transition to a clean energy system, requiring differentiated efforts between the most emitting countries.
The goals of the Paris Agreement are to maintain a healthy rise in global average temperatures for below 2 degrees Celsius and limit global warming to 1.5 degrees Celsius this century.
The use of renewable energies combined with the electrification of transport can enable the achievement of global climate goals, according to the analysis of the International Renewable Energy Agency (IRENA). The most relevant thing is that you can do it in a immediate and substantial.
It is predicted that by 2050, electricity produced from renewable energies will have a share of almost 50%. In the coming years, 86% of global energy demand will be able to be supplied with clean energies given the emergence of the renewable hydrogen as a fuel.
The transition to a more sustainable energy model requires $ 15 trillion by 2050. Although the sum is high, it is expected that it can be reduced considerably as solar energy becomes more competitive and decreases its implementation costs.
The study shows that for every dollar spent on the energy transition, there would be a benefit of between 3 and 7 dollarsor $ 65 trillion and $ 160 trillion in cumulative terms over the period up to 2050.
The total cost of the energy system includes the cost of production and the cost of integration. The cost of production is associated with the production of energy. It is usually measured with the indicator Level Energy Cost (LCoE).
Integration costs are linked to connection to the system, so that supply meets demand.
As the LCoE of renewables declines rapidly, their fluctuating characteristics undermine some of the benefits of cost reduction. However, they can decrease considerably depending on the flexibility of the energy system.
Although there is progress in the implementation of renewable energies, its pace is very slow. Even the broadcasts have increased by 1% per year on average over the past five years.
To achieve the goals of the Paris Agreement, greater government involvement is needed. By mid-century, the global economy will be larger and jobs created in the energy sector will boost global employment by 0.2%.
10.3 million people in the field of renewable energies around the world and it is expected that there will be 24 million by 2030.
An example is Germany. With the use of renewable energies, it has avoided the generation of more 100 million tonnes of CO2 in 2018.
