How Does Your Energy Source Create Electricity?

How does your energy source create electricity?
1. Photovoltaic (PV devices) or “solar cells” change sunlight directly into electricity. PV cells are grouped into panels that can be used in a wide range of applications from singe small cells that charge just calculator and watch batteries, to systems that power homes, to large power plants that cover numerous acres.

What is its potential?
Because convenient and affordable energy can help a household’s productivity and income potential, its availability can help families and communities break free of poverty.

How much electricity does it use?

This energy is usually calculated in what is called “kilowatt hours” (kWh) or 1,000 W, which equals to the amount of electricity needed to light up a 100 W light bulb for 10 hours.

This was originally developed in order to provide electricity for satellites, but these days many of us own calculators powered by solar cells.

Interesting facts (these aren't actually necessary, just in case you needed something to write)

It takes 8 minutes 19 seconds for light to travel from the sun’s surface to earth.
In 5 billion years the sun will run out of fuel.
A Swiss scientist, Horace de Saussure invented the world’s first solar energy collector, or ‘hot box’ in 1767.
In the 1830s British astronomer John Herschel used a solar energy collector box to cook food during an expedition to Africa.
Albert Einstein won the 1921 Nobel Prize in Physics (awarded in 1922) for his experiments with solar energy and photovoltaics.
Enough sunlight falls on the earth every hour to meet the world’s energy demands for an entire year.
If we covered a small fraction of the Sahara desert with photovoltaic cells, we could generate all the world’s electricity requirements.
All TV and communications satellites are powered by solar energy using photovoltaic cells.
Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days,...
