The majority of the world’s energy consumption is still supplied by fossil fuels. Even though this type of source has negative impacts on environment and has a limited quantity, the world still hasn’t found a satisfying solution to replace it.
The improvement of technology creates another alternative, which is the natural and renewable energy. The use of natural energies grows each year, but its development is low because their cost are more expensive than fossil fuels, therefore more economic sacrifice. A study shows that even though the a great number of Americans favor green energy, most of them are less willing to pay more for it. Another downfall of natural energies is that they’re climate-dependent and need to be backed-up by a more reliable source, such as fossil fuels and nuclear, which add expenses to the costs. Some say that “trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work”. So should we change our aim for a green energy and change it to develop nuclear energy ?
But, there is still hope for natural energy ! In just a dozen years, Germany has managed to replace around 30% of its nuclear and fossil fuel produced electricity with natural energy. This phenomenon could be explained by how Germany’s power supply is managed. In comparison to a centralized power plants that aims to meet the demand of energy in most countries, the German system is decentralized and includes more than 2 million small and medium scale renewable producers (businesses, farmers, villages, towns, co-ops, etc.) whose numbers keeps to increase over time. Their output are traded from locality to locality and even internationally via intelligent networks.
This transition was accentuated with Merkel’s decision to shut down a third of Germany’s nuclear reactors, following Fukushima’s disaster in 2011. This decision encouraged renewable energies to progress and fill the gap.
What happens in German shows us that with motivated leaders and the right policies, it is possible to little by little replace non-renewable energy source with renewable source. Much technological progressions are still need to be done because as we saw earlier, green energy is still expensive and unstable. We have to keep in mind that increasing the uses of green energy is possible.
