This article describes how the cost of renewable energy sources is becoming cheaper and cheaper. Solar energy should be about 50% cheaper at the end of this year than it was at the end of last year, and prices are expected to continue going down. Equipment for renewable energy sources keeps getting cheaper, and is expected to keep getting even cheaper, while the financing (which is more expensive at the moment) is also expected to get better. This obviously is great, there isn't a single bad thing about this news. As we run out of non-renewable energy sources, like fossil fuels, we're going to need to turn to renewable energy sources. This will also be better for the planet in general, since we won't be burning fossil fuels once they run out, and polluting everything. Energy sources such as solar energy don't produce hazardous waste, don't pollute, are efficient, and could produce a lot more energy than they do now if significant investments are put into them. The downside would be the space taken up by giant solar panels, windmills, et cetera. There are companies planning to put satellites into space which can harvest solar energy and beam it back to earth, though, such as the one discussed in this article. This would solve the space problem, and basically just be a win-win situation for everybody. There are other ways these renewable energy sources are moving forward, such as government incentives, which is even better, since they obviously realize that we need to move in that direction and are steadily trying to reach this goal. Hopefully with these continually decreasing costs, more power companies will invest in solar and wind energy, and we can move to cleaner, more efficient, renewable energy sources.
