The fossil fuel coal is formed when - sub-surface mines are dangerous for
peat is altered physically and miners as tunnels can collapse and
chemically. This process is known as built-up gas can explode; they also
"coalification" and can take as long as create subsidence(ground level lowers
400 million years to complete. when the coal is removed)
- surface mining causes erosion & water
pollution and decreases biodiversity by
Coal reducing plant and animal habitat
- burning of coal by large-scale factories
to power industry has led to acid rain in
some regions
Oil, or petroleum, comes from the
liquified, fossilised remains of plants
- threats to waterways, plants and
wildlife due to oil spills and increased
and animals that lived hundreds of infrastructure in natural areas
millions of years ago; once oil sources - air pollution, smog and increased
are depleted, they cannot be greenhouse gas emissions
replaced. - many of the countries where oil can be
found are politically unstable ­ around
Oil 70% of the world's oil reserves are
believed to be located in the Middle East
The result of decomposing plants and
animals that were trapped beneath

using dynamite and then processed - highly flammable substance and needs
Gas and piped through thousands of miles to be produced in highly managed
of pipelines for cooking, heating circumstances
homes and fueling vehicles.
Non- renewable sources: fossil fuels which are formed from the partly decayed remains of plants
and animals. They're finite which means they can only be used once.

Renewable energy sources: energy that comes from resources which are continually replenished
such as sunlight, wind, rain, tides, waves and geothermal heat
Info Issues
Large banks of solar panels are
installed on a south facing roof
- No sunlight available at night
to provide electricity
which harness the sun's rays
and turn them into electricity.…read more
