According to Japan’s Ministry of Economy, Trade and Industry the country’s energy from renewable sources accounted for only 1 percent of the total energy gneration in 2009. And that number has improved in much 2011 though efforts, verbally at least, have increased due to the Fukushima Incident.
Why is this so? Well, it takes area of 65 square kilometers of solar panels to generate the same amount power of one nuclear reactor. Now that is not efficient, is it? The same problem goes for wind power generation. And we have yet to talk about the cost here.
No, the aim for 20% of energy from renewable sources by 2020 in Japan just seems near impossible though an accident of the size we had in Fukushima may well change that. One has to ask why must we wait for such things to happen before we act.
