1. I drive somewhere on a regular basis, use a remote control for the television, and turn a light switch on.

To conserve, I can condense daily errands into 2 trips per week, I would use less gas. I can keep the television off when I'm not using it, same with the lights.

Biomass was used as an alternative in countries where coal was not available.

3. Landscape disturbance, acid mine draining, and air pollution are three impacts of the use of coal. Landscape disturbance is when the Earth is stripped away by means such as surface mining. Surface mining is when the topsoil and overburden is removed to get to the coal. Acid mine draining is when the combined action of oxygen, water, and bacteria form to create sulfuric acid.

This seeps into the coal and is washed away, contamination waterways. Air pollution occurs when the large amounts of coal dust is released into the atmosphere.

4. Lignite has a high moisture content and is crumbly. It has low energy content. Bituminous coal has a low moisture content and high carbon content. Anthracite is 86-98 percent carbon. It is rare.

5. Coal was formed during the Carboniferous period, when the climate was warm and humid. There were huge swamps with forests of primitive plants. These conditions led to the accumulation of large amount is plant material that was converted into coal deposits by heat and pressure. Oil and natural gas formed from tiny marine organisms whose bodies accumulated in large quantities on the sea floor and became compressed. Heat and pressure converted the organic...
