Though the Rocky Mountains are a spectacular site, I found myself more excited to see all of the wind turbines on the 15-hour drive from Minneapolis to Colorado Springs. This ultimately resulted in a research extravaganza, as I wanted to know more about how wind energy works and what the US was doing to improve renewable energy.
Lets start with a few Minnesota wind facts :
• Total installed wind energy capacity is currently 1752.16 megawatts
• Total wind energy potential is 657 billions of kWh/year
• Currently ranked at 4th in US for current wind energy output (Go Minnesota!)
On average, one household will consume around 4,250 kilowatt-hours per year , so think of how many homes can be powered if Minnesota was reaching its wind energy potential.
I also came across this article that came out today in Scientific American that discusses the great steps that Hawaii is taking towards renewable energy. Recently, Hawaii signed an agreement with the US Department of Energy (DoE) that outlines a plan to obtain 70 percent of its power from clean energy by 2030, in which 40 percent will be from renewables like wind farms.
As of right now, the state relies on imported oil for 90 percent of its power. If a man-made or natural disaster were to occur that would prevent shipment of oil, Hawaii cannot plug into the mainland’s electrical grid, making them extremely vulnerable. So not only will they gain energy security, but the cost of electricity will also lower by reducing the amount of money spent on shipping money to foreign countries for oil (10% GDP).
The largest source of renewable energy will be makani, or wind. There are currently two proposed farms for Lanai and Molokai islands that will together generate a total of 400 megawatts of electricity, which will provide 25 percent of Oahu’s total generation capacity. Considering that over 70 percent of the stat’s population lives in Oahu, that’s a lot of energy! Solar water heating, geothermal energy, and the novel technologies in ocean thermal plants will also be used to provide the Hawaiian islands with clean, renewable energy.
