Energy transition and sustainable development
The energy transition is the set of changes in the production, distribution and consumption of energy in a territory in order to make it more ecological.
It prioritizes renewable energies such as wind, solar and hydropower, among others, but also energy saving, reduction of consumption and energy waste.
Fossil fuels have a negative impact on the environment and human health, creating greenhouse gases and a 3° temperature increase by 2040.
This is why renewable energies offer various advantages such as the battle against global warming, the reduction of greenhouse gases, the eventual abandonment of nuclear power, the reduction of consumption, the reduction of inequalities in energy access and in order to protect the health of populations.
However, after the Paris agreements, only 16 countries raised their greenhouse gas emission reduction targets. Moreover, to avoid a temperature increase of 1.5°C by 2050, man-made C02 emissions will have to fall to zero, unfortunately there is currently an increase in C02 emissions and an 8% decrease in investments in renewable energies.
On the other hand, it should be noted that renewable energies are not without danger for the environment, they can create disturbances or even the disappearance of habitats, ecosystems and migratory flows of several species, but also the modification of local microclimates, the emission of pollutants such as hydrogen sulphide, etc.....
In conclusion, green energies are not without risk and represent significant production and access costs. This is why the implementation of a sustainable energy model using renewable energies requires a significant reduction in energy consumption and an increase in investment in the sector.
