Fast facts about solar energy
When considering renewable energy options, there is so much information out there. How can you know what is true and what’s not? We’re here to help. Here are 10 fast facts about solar energy, including why we need it!
Read and consider whether you are doing enough to conserve energy and reduce use of fossil fuels (source: National Geographic):
1. Each hour, of each day, more energy from the sun reaches our planet than is used by the entire global population in an entire year.
2. The projected annual growth rate for renewable energy sources is 7.2%, the fastest rate.
3. Over 3,500 square miles of federal land are currently awaiting permits for solar power development.
4. The U.S. ranks 5th in the world among nations producing the most CO2 home emissions (behind Kuwait, Bahrain, UAE and Estonia).

5. Use of electric lights results in 1/2 the pollution of all the cars on the road. Switching to LED lights use 75% less energy.
6. Solar PV is rated number 1 in growth for energy technologies.
7. MIT scientists have discovered a way to store solar power after the sun goes down (how cool is that?)
8. Every 2 months, a typical U.S. home uses one ton of coal to generate electricity.
9. Switching to a solar hot water heater (using solar thermal panels) can drastically reduce fossil fuel use. According to Wikipeida:
The typical 50 gallon electric water heater uses 11.1 barrels of oil a year, which translates into the same amount oil used by a typical 4 door sedan driven by the average consumer.
10. Between lower costs and tax incentives/rebates, PV solar panels are a viable option for just about any homeowner with a south-facing roof. Payback on investment, through energy savings, is about 7-9 years.
Why not switch to solar energy? Whether you install PV panels, thermal panels, or merely use smaller solar-powered devices to charge appliance batteries, you’ll be reducing your carbon footprint.
We can all tread a bit more lightly.
