Coal Mining

Coal is a combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable […]

Geothermal Energy

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is energy that determines the temperature of matter. Earth’s geothermal energy originates from the original formation of the planet, from radioactive decay of minerals and from volcanic activity. The geothermal gradient, which is the difference in temperature between the core of the […]

Wind Power

Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions during operation. A large wind farm may consist of several hundred individual wind turbines which are connected to the electric power transmission network. The construction of wind farms is not universally welcomed because of their […]

The Perpetual Car

Electric cars are the greenest alternative in the personal transportation industry. They do not emit any (or much less carbon emissions than their conventional counterparts, but they do utilize questionable raw materials, such as the metal that is contained within the batteries. There are some major advantages to owning a green car but there are […]
