We have all seen calculators with solar cells, that enable the device to work without any batteries, and can be used for unlimited time period as long as there’s enough light.
These solar cells that are present in calculators and many other devices are also called photovoltaic (PV) cells. As the name depicts, these cells have the capability of converting sunlight directly into electricity.
A group of cells can also be connected together electrically, fitted into a frame to form a solar panel. Moreover, these solar panels can be combined together to form larger solar arrays, similar to the ones operating at Nellis Air Force Base in Nevada.

Wind energy is being used as a reliable source of energy for a long time. The Babylonians and Chinese used wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that.

Tidal energy is used to generate electricity through the use of tidal energy generators. By placing large underwater turbines in areas with high tidal movements, they are used to capture the kinetic motion of the ebbing and surging of ocean tides in order to generate electricity.

Tidal energy is a great source of clean renewable energy, but most of us don’t know about how it works? Every day, the tide moves a huge amount of water twice, and harnessing it could provide a great deal of energy, which can make up around 20% of Britain’s needs.

Bernie Sanders of Vermont introduced an exciting new bill to Congress last week. The bill defines a plan to install 10 million solar roofs and 200,000 solar water heaters over the next 10 years through tax rebates and incentives. According to the bill, the installations would equal 30 GW of clean energy or the equivalent of 30 nuclear power plants.
