As written on Solar-Aid's website, here's a few things you might not know:
earth receives more energy from the sun in just one hour than the world
uses in a whole year.
- Two billion people in the world
have no access to electricity.
- Building a small solar charger for a radio can
cost around £5 and can sell for three times the price in Africa .. Solar Aid help to set up small solar
businesses so people can earn a living.
rural poor in Africa use kerosene lamps, which are heavily polluting in
CO2 and bad for their health, but a solar lamp would be cheaper and
better for the environment.
- Solar panels are guaranteed typically for 25 years and have a life expectancy of at least 50 years.
- Africa has the
lowest fossil energy use of any world region, yet the continent is the
most vulnerable to climate change. Signs of a changing climate have
already emerged there: disease and melting glaciers in the mountains,
rising temperatures in drought-prone areas, and sea-level rise and
coral bleaching along the coastlines.
- Respiratory diseases
caused by toxic smoke from cooking fires kill 1.5 million women and
children each year. Yet a solar cooker, which is much safer, can be
easily built from cardboard and waste reflective material.
