Solar energy is one of the most environmentally friendly alternative energy sources! Solar energy can be used to power houses, mobile homes, warehouses, and anything else that requires access to electricity to function. Solar energy can even be used to fly planes! One way to put solar energy to good use is to provide power to previously “off-grid” and rural communities. For example one climate change group has provided energy to many Kenyan villages because it is cost effective, and environmentally effective.
