Answer:

Food

Solar energy (sunlight) is crucial for our survival on Earth. Sunlight (visible light) falls on the leaves of plants where a process called photosynthesis takes place. The energy (red and blue light) that plants absorb from the Sun is the energy supply for the building of simple sugars that are then converted into starch for storage. The plant can then use this energy store to grow. When we eat plants, the stored chemical energy from the plant is transferred to us. This provides us with an energy store for all our life processes such as growing, moving, making sounds and breathing. All life is dependent on the Sun’s energy.

Electricity

Just as solar energy is transformed to a useful form of energy in plants and animals (through the food chain), scientists have discovered that we can also convert solar energy into electrical energy (electricity) for our needs.

There are at least 2 ways currently used for converting solar energy into electricity:

Solar (photovoltaic) cells are used to convert solar light energy into electricity.

Concentrating solar power (CSP) allows a large area of sunlight to hit a trough where solar collectors (lenses, mirrors and tracking systems) concentrate it into a beam that boils liquid in order to make steam, which moves turbines to make electricity.

Using solar energy for electricity is environmentally friendly. It does not produce greenhouse gases or other atmospheric emissions. The major component for this power generation is just sunlight. Using this power source means we can reduce our use of fossil fuels, which are a limited resource.

With new technology, bright sunlight is not needed to generate electricity from solar energy. Solar cells can work on gloomy days if the temperature is moderate.
