Solar Energy Statistics and Solar Power Trends
The United States solar industry has increased an estimated 116% per year with 45% increases seen in a single quarter of 2012. This growth is primarily attributed to the decreasing costs for installing solar utilities, dropping 45.8% since 2010. Residential solar installations have also seen a 21.8% drop per watt. The following solar energy industry statistics are outlined below for an overview of this changing industry.

5 Interesting Facts About Solar Power
1. Solar and wind power energy have 100 times more energy yield than nuclear or fossil energy.
2. The earth receives more energy from the sun in a hour than is used in the entire world in a single year.
3. The area of roof space available in Australia is able to provide the nations entire electricity by using solar panels.
4. It would take 3% of the world’s land area to supply the electrical needs of the world by solar power.
5. Wind is a form of solar power generated by the uneven heating of the Earth’s surface.
The Future of Solar Power Industry
In order for solar energy to become more prominent the following technological hurdles must be surpassed.
• Solar panels must increase in efficiency by at least 20% to over 40%. This can be done by allowing for more wavelengths to be used, cheaper semiconductor methods, and more efficient manufacturing techniques used.
• Huge areas of desert can be covered in PV solar panels but must first address the environmental impacts of that.
• New direct current transmission lines can be installed that are smaller and cross the continent.
