It’s hip, it’s cool, it’s trendy and it’s green. Solar power is increasingly becoming the topic of conversation as the world shifts from filthy coal, oil and other fossil fuels, to the clean and renewable energy provided by the sun.
Here’s some fascinating statistics, facts and trivia about Solar power!
- It would take only around 0.3 per cent of the world’s land area to supply all of our electricity needs via solar power.
- The area of roof space available in UK is enough to provide all of the nation’s electricity, using solar panels.
- Weight for weight, solar cells generate the same amount of electricity over their lifetime as nuclear fuel rods, without the hazardous waste. All the components in a solar panel can be recycled, whereas nuclear waste remains a threat for thousands of years.
- Solar have 100 times better lifetime energy yield than either nuclear or fossil energy system per tonne of mined materials.
- The amount of energy that goes into creating solar panels is paid back through clean electricity production within 2 – 3 years, depending on where they are used. This compares with a serviceable life of several decades.
- The theoretical limit for silicon based solar cells is 29% conversion efficiency. This might be achieved in the next decade or two. Currently, Solar modules generally available, have efficiencies anywhere from 12% to 17%.
- The Earth receives more energy from the sun in one hour than is used in the entire world in an entire year.
