Alright so this is a pretty trivial article on energy crisis and newer, less costly renewable energy products. There are countless articles, opinion's and political views of the different energy solutions to better reduce the harmful environmental impacts to the Earth's environment as well as our so called diminishing fossil fuel supply.
My favorite alternative energy technology available is definitely wind energy. I believe wind to be far more superior to the other alternatives for various reasons. Versus Solar, Wind has I higher yield of energy output with less opportunity cost of land. Wind turbines have a significantly smaller footprint than a solar matrix. With less land being consumed, the land can be used for agriculture, etc.
It's optimal compared to the bio-fuels as the bio fuels still produce carbon and the opportunity cost of the organic material (corn) used in production could be better used as livestock feed or food.
Another pro for Wind technology is that wind tech is not necessarily land-locked. Wind turbines can be erected in a floating apparatus anchored to a seabed. And advantage over solar and less costly to do than aquatic Geo-thermal technology.
To take advantage over the opportunity in Wind, you could purchase shares or calls in the Wind Energy producers or equipment manufacturers. I like the new First Trust Global Wind Energy (ETF) (NYSE:FAN). Its near it's 52 week low and is a great opportunity to get in.
