Biodiesel is diesel fuel made from renewable sources of carbon such as used vegetable oil or animal fats used in cooking. In diesel engines it can be used as a direct substitute for petrodiesel fuel made from petroleum.
Biodiesel is clear amber liquid. Its consistency is similar to that of petrodiesel. Biodiesel fuel can be used on its own in a diesel engine or mixed with petrodiesel. Some people mix small amounts of biodiesel into gasoline (gasoline additive) to decrease its air-pollution qualities. (more…)

It is often useful to know how much energy is being changed from one form to another. For example, natural gas companies need to have a way to measure the fuel demands of their customers so they can provide enough natural gas advantages when it is most needed. (more…)
Renewable energy sources cannot run out and causes so little damage to the environment that its use does not need to be restricted. No energy system based on mineral resources is renewable because, one day, the mineral deposits will be used up. This is true for fossil fuels and uranium. The debate about when a particular mineral resource will run out is irrelevant in this context. Renewable energy sources are replenished continuously.
Renewable energy sources—solar, wind, biomass (under specific conditions), and tides—are based directly or indirectly on solar energy. Hydroelectric power is not necessarily a renewable energy source because large-scale projects can cause ecological damage and irreversible consequences. Geothermal energy heat is renewable but must be used cautiously to guard against irreversible ecological effects. (more…)
Wind energy alongside solar energy is one form of renewable energy and its supply is abundant in earth. Most people distinguish between wind energy and solar energy. However, this distinction is not necessary because wind that powers wind turbines is itself a form of solar power. It is implicated that wind energy source are from sun. Atmosphere heating by sunlight is the main caused of wind and its movement. Other factors like earth’s surface irregularities in shape and earth rotation also play role in wind formation and also consider as wind energy source.
What causes wind flows?

Almost all fossil fuels use is by burning them to create energy. Burning process then produces waste products due to impurities in the fuel. There are few particulates as a resides and some gases such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. These waste gases are then become air pollution orfossil fuels affecting our environment in destructive ways.
There are several types of air pollution: (more…)
