You can build your own solar panels from home and most of the parts can be found from your local hardware store. If you're interested take a look at these website : i n p l i x . c o m
One makes electricity while the other just heats
Static electricity is useful in several ways. It causes attraction between particles, which makes it useful in air pollution control and photocopier technology.

sub-atomic particle: which makes up an atom: which makes up molecules: which makes up DNA: which make up organelles (cell parts): which makes up cells: which makes up tissues: which makes up organs: which makes up organ systems: which makes up organisms.
It's not necessary at all. But the fact that it can be usedas a navigational tool makes it quite useful.
They generate electricity......
I think you got your concepts wrong there... Fossil fuels include coal, oil and natural gas ONLY. Renewable energy resources include SOLAR POWER, which makes use of PHOTOVOLTAIC CELLS to convert light energy into electrical energy using certain metallic compounds which include cadmium telluride. Therefore, photovoltaic cells are a part of solar-powered systems which provide a renewable energy source for electricity. :)
Photovoltaic solar cells produce electricity using solar power. Since their energy comes from the sun, they do not produce any pollution. This makes them environmentally friendly.

Sedimentary rock are made of materials that could show what lived where. Also they are the only rock to hold fossils.
Why is any car useful? Your question makes no sense.
It makes you clean and it makes you smell good.
it makes a useful tool because it canhelp u find al diferent kind of species

Their properties
Most diamonds are used in industry and not in jewelry. Their hardness makes diamond useful as a cutting tool.
There are a few different things that will make a climate graph more useful. Having data for a long period of time makes this graph very useful.
