How much more expensive is solar energy than fossil fuels - 0 views

  •  
    "Fossil fuel power stations typically cost about $2.1 dollars per watt to build solar stations around $7 at present. The efficiency is increasing and costs are falling. This of course does not represent the cost to the consumer. In addition it does not take into account all the various other costs and the advantages and disadvantages of each. Fuel (fossil stations), poor sunlight (solar stations). Maintenance costs are similar for single plants but solar stations do not have the capacity of fossil fuel stations."

How Much Does Biodiesel Reduce Air Pollutants? - 0 views

  • Biodiesel fuel almost eliminates the air pollution caused by petroleum based fuels. Toxins that can cause cancer are virtually cut to zero by the use of biodiesel fuel instead of regular diesel fuel.

Electricity from Geothermal Energy - 1 views

  • The heat from the earth's own molten core can be converted into electricity. This core consists primarily of extremely high temperature liquid rock known as magma. This "geothermal" heat circulates within the rock or is transferred to underground reservoirs of water, which also circulate under the earth's crust. Because of the near limitless ability of the earth to produce magma, and the continuous transfer of heat between subsurface rock and water, geothermal energy is considered a renewable resource.

Because of the near limitless ability of the earth to produce magma, and the continuous transfer of heat between subsurface rock and water, geothermal energy is considered a renewable resource. Geothermal resources have been harnessed as an energy source since the dawn of civilization, when natural hot springs were first used for cooking and bathing. The geothermal resources tapped to generate electricity are far more intense than those used for space heating and can reside as deep as 10,000 feet below the earth's surface. Capital costs for the construction of geothermal power plants are much higher than for large coal-fired plants or new natural gas turbine technologies. But geothermal plants have reasonable operation and maintenance costs and no fuel costs. Though more expensive than wind power in most cases, new geothermal electricity generation facilities are increasingly competitive with fossil options."

Where does biofuel come from - 0 views

  • Biofuel comes from petroleum products which come from below the ground. Ethanol, however, the "bio" part of biofuels, comes from corn.

What Is Hydrogen? (with picture) - 1 views

  •  
    "Hydrogen is a highly flammable chemical element that occurs in great abundance throughout the universe. In fact, this element makes up approximately 75% of the universe, by volume, and it appears in a very large number of compounds, especially those which make up various organic materials."

History Of Geothermal Energy - 0 views

  •  
    "The history of geothermal power can be traced back to over 10,000 years ago to the American Paleo-Indians at their settlement in hot springs. This history has been uncovered through the use of archeology and shows the Indians used the hot springs for activities including, bathing and heating. It is also believed the springs were seen as a healing source."

Hydrogen economy - Wikipedia, the free encyclopedia - 0 views

  •  
    "The hydrogen economy is a proposed system of delivering energy using hydrogen. The term hydrogen economy was coined by John Bockris during a talk he gave in 1970 at General Motors (GM) Technical Center.[1] Hydrogen advocates promote hydrogen as a potential fuel for motive power[2] (including cars and boats), the energy needs of buildings and portable electronics. Free hydrogen does not occur naturally in quantity, but can be generated by steam reformation of hydrocarbons, water electrolysis or by other methods. Hydrogen is thus an energy carrier (like a battery), not a primary energy source (like coal). The feasibility of a hydrogen economy depends on issues of electrolysis, energy sourcing, including fossil fuel use, climate change, and sustainable energy generation."

Does geothermal energy cause pollution - 0 views

  •  
    "Geothermal energy uses hot water or steam from deep in the Earth. As a consequence it does not require fuels which produce emissions. However there are hot water (condensate) releases which may cause thermal pollution."

Solar power - Sustainable green energy to protect our economy and environment | PARTHA ... - 2 views

  • A Solar Energy system can operate entirely independently, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations, making it more practical and cost-effective than the supply of utility electricity to a new site.

Cost of Geothermal Energy - 0 views

  •  
    "Certain studies have shown that a geothermal power plant that could be considered as economically competitive would cost at around $3400/kw installed. Yes, the cost of the construction of a geothermal power plant is much higher compared to a facility producing natural gas, however, the cost of electricity production of the two in the long run would be similar. Initially, the construction cost of the geothermal plant would be 2/3 of the total cost. On the other hand, with a natural gas facility, the cost of the fuel is 2/3 while construction cost is just 1/3 of the total cost.  So this is where geothermal power plant and natural gas energy come into a standoff. In the long run, production rates stabilize and the cost of production for both plants become competitive. One good thing about the pric"
