Geothermal energy is one that uses the heat inside the earth.
Geothermal energy is one of the most promising because it is cleaner and more abundant. Geothermal energy does not depend on the weather terms, thus becomes one of the most profitable, because the heat inside the earth is inexhaustible.
The most common uses are:
Various industrial uses such as milk pasteurization.
The introduction of heating whole districts and individual houses.
Crops in greenhouses during the snowfall.
Reduce the time of growth of fish and crustaceans.
Among its advantages, we can highlight:
It is a low cost resource.
Contribute to both the generation of energy (electricity produced) and with direct heat uses.
Avoids reliance on foreign energy.
The waste produced is minimal and cause less environmental impact than fossil fuels (oil, coal, etc.).
Do not produce any combustion.
Many countries using geothermal energy, but only Iceland produces nearly 100% of its energy through the earth's internal heat.
Geothermic energy is used by countries like:
The vehicles with alternative fuels are equipments that use fuels different from those who come from the oil.
The alternative fuels are formed(trained) by chains of atoms of carbon. The alternative fuels, they have not so much energy.
-Having in it counts the problems related to the environmental pollution and the energetic world, there becomes necessary increasingly
the employment of the alternative fuels in the vehicles.
Alternative fuels, also known as non-conventional or advanced fuels, are any materials or subtances that can be used as fuels, other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil), coals, propane, and natural gas), and nuclear materials such as uranium.
Some well known alternative fuels include biodiesel, bioalcohol (methanol, ethanol, buthanol), chemically stored electricity (batteries and fuel cells); hydrogen, non-fossil mehtane, non-fossiL natural gas, vegetable oil and other biomas sources.
Public Transport Development
Public transport is the transport medium in which the passengers do not own these vehicles. Public transport services may be provided by public or private companies.Public transport is far more effective than individual transport in terms of energy consumption, except the plane, which is the most polluting mode of transport per passenger.In proportion to travelers carrying, public transport take up much less space, consume less energy in use, consume fewer resources in its construction, the private car.
Public transport within the city
The city councils of cities put at the disposal of the citizens public transportation, transport can be:
-buses: The buses can carry more than 60 people using the same area as two cars.
-rail:Public transport by rail or underground reserved not suffer from problems of congestion.
