How does sunlight indirectly generate coal?
It powered the plants until they died millions of years ago, to eventually become coal.
Explain how coal is a store of solar energy?
Coal is composed of old plant material that was chemically altered over the course of millions of years. The coal contains energy from sunlight that the plants captured and stored via photosynthesis.
Why do spacecraft use solar cells to generate electricity rather than burning coal?
Burning coal releases harmful gases and it may have some bad effects in space. Solar power is more efficient
Would solar panels generate more power at a higher altitude?
When you are at a higher altitude there is less air to dissipate the sunlight, and solar panels increase in efficiency at colder temperatures.
Can sunlight be used for a laser?
No. A laser is a bean of light that propagates in one direction with little spread and generate light only over a very small range of wavelengths. The rays of sunlight are parallel only because of our great distance from the sun. Sunlight can be focused to a point using mirrors or lenses, but will spread out beyond that point, rather than as a coherent beam light a laser. Additionally, sunlight consists of the entire spectrum of light.

What does coal generate?
CO
Which type of coal is mainly used to generate electricity?
bituminous coal
What does burning coal generate?
CO
What can be made directly or indirectly from coal?
khol eyeliner, electricity
Does NZ use coal to generate electricity?
no
Do giraffes need sunlight?
Indirectly; plants require sunlight to grow, the Giraffe requires the plants to feed on
What fuel is used the most to generate electricity?
The coal is used mostly to generate electricity.
How much coal does it require to generate 1000 KWH of electricity?
It takes one ton of coal to generate an average of 2500 KWH of electricity.
What are some resources used to generate electricity in energy stations?
Both renewable and non-renewable resources are used to create electricity. A few of them are wind, water, sunlight, coal, and nuclear resources.
