One of the easiest ways to fight global warming is by implementing clean power sources, and photovoltaic solar cells are an increasingly popular choice on this list. After all, sunlight is free, abundant and consistent--especially if you live in a temperate climate.

These solar inventions range from silly to dead serious. It seems that everything from handbags to canopies, curtains and loungers can be slapped with photovoltaic solar cells to make them more eco-friendly and help stave off global warming. There are even solar panels that you can literally peel and stick onto your home, just like a large bumper sticker.

Wearing a handbag with solar cells on it to the mall won’t necessarily take you right off the power grid, but this relatively small statement does help to raise awareness about global warming. If you want to make a bigger impact, try a solar panel vehicle or install solar paving around your home.

These 37 inventions all utilize solar cell technology in some form. In the fight against global warming, every energy-efficient effort counts--no matter how large or small it is.
