2. The sun's light (and all light) contains energy. Usually, when light hits an object the energy turns into heat, like the warmth you feel while sitting in the sun. But when light hits certain materials the energy turns into an electrical current instead, which we can then harness for power. • Old solar technology uses large crystals made out of silicon, which produces an electrical current when struck by light. Silicon can do this because the electrons in the crystal get up and move when exposed to light instead of just jiggling in place to make heat. The silicon turns a good portion of light energy into electricity, but it is expensive because big crystals are hard to grow. • Newer materials use smaller, cheaper crystals, such as copper-indium-gallium-selenide, that can be shaped into flexible films. This is the newer solar technology, however, is not as good as silicon at turning light into electricity.

3. Solar cars are a car but instead of using petrol it use’s energy from the sun solar cars harness energy from the sun, converting it into electricity. That electricity then fuels the battery that runs the car's motor. Instead of using a battery, some solar cars direct the power straight to an electric motor.

4. Solar water heaters work by installing thermal panels on an unshaded, south-facing portion of a roof. These panels collect heat from the sun's rays to warm a liquid that moves through pipes connected to the panels

5. What is renewable energy solar • Renewable energy is energy generated from natural recourses-such as sunlight, wind and rain, tides, and geothermal heat-which are renewable[naturally replenished]
