Renewable Electricity, many reasons for hope
In a previous post, I mentioned the rough figure of 42% of the energy in the world devoted to electricity production, sometimes, when we talk about energy and climate change we only think in electricity. It is a mistake I do frequently. So, OK it is just 42%, it is not all but it is almost half of the problem. So it seems a good starting point for the solution as well. And though the situation is not wonderful and we are in a hurry, there are some sings for hope just in the electricity production data by country. They are in the following figures:
The so-called top producers correspond to the 16 countries that concentrate the 80% of consumption, the data come from the Wikipedia and are from 2009-2010, in this moment they should be better for many places.
Anyway, my hope comes from those facts:
- The top producers are less renewable than the rest. But even there, there are 2 countries with most electricity from renewables, so it is possible to maintain a “big” electricity system this way.
- “The rest” show a lot of countries very renewable. It is hopeful because they should be the ones needing more new energy, so they can install it renewable. In th other hand this confirms that the problem and solution is concentrated in a few bunch of countries.
- Among “the rest” hydro power is their main source of renewable energy, among top consumers too, but with significant amount of others as wind, solar or even Geothermal. This is interesting as the future and present should come from them.
- Finally, electricity can be the way to decarbonize other sectors as transport (the road is the most important contributor there)
