Scientists have come up with a more efficient way to split ocean water and turn it into sustainable, clean hydrogen fuel. They created a flexible plastic film that acts as the catalyst to begin splitting ocean water, without requiring the high energy input that current methods need.

geothermal pollution

shared by wooddan99 on 26 Sep 13 - No Cached

Unlike fossil fuel power plants, no smoke is emitted from geothermal power plants, because no burning takes place; only steam is emitted from geothermal facilities. Emissions of nitrous oxide, hydrogen sulfide, sulfur dioxide, particulate matter, and carbon dioxide are extremely low, especially when compared to fossil fuel emissions. The binary geothermal plant, which currently represents around 15% of all geothermal plant capacity, along with the flash/binary plant, produce nearly zero air emissions. Even dry steam plants, which are considered to have the highest levels of air emissions, are considered environmentally benign compared with fossil fuels. For example, Lake County, California, downwind of The Geysers, has met all federal and state ambient air quality standards for almost 25 years. There are 21 power plants at The Geysers, comprising a significant complex of electric generation facilities, yet even despite this, air quality is excellent. At The Geysers, air quality has even improved as a result of geothermal development because hydrogen sulfide, which would ordinarily be released naturally into the atmosphere by hot springs and fumaroles, instead now passes through an abatement system that reduces hydrogen sulfide emissions by 99.9%.

biofuel pollution form

shared by hollale00 on 24 Sep 13 - No Cached

Biodiesel is a type of bio-fuel which is used to fuel cars and other vehicles. Biodiesel is used as alternative petroleum oil. Biodiesel is special because it is a clean resource and is safe to use in our environment, compared to other fuels that pollute the planet. Biodiesel is made from renewable resources which make it easier to produce. Biodiesel also lubricates car engines, which decreases engine wear, making the engine last longer. Speaking of engines, biodiesel is compatible with most car engines that run on diesel. According to researchers, biodiesel can reduce the risk of cancer, which the emitting of petroleum oil have been known to cause.

" Geothermal Electricity Production Most power plants need steam to generate electricity. The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle. Dry steam power plants draw from underground resources of steam. The steam is piped directly from underground wells to the power plant, where it is directed into a turbine/generator unit. There are only two known underground resources of steam in the United States: The Geysers in northern California and Yellowstone National Park in Wyoming, where there's a well-known geyser called Old Faithful. Since Yellowstone is protected from development, the only dry steam plants in the country are at The Geysers. This geothermal power plant generates electricity for the Imperial Valley in California. Credit: Warren Gretz Flash steam power plants are the most common. They use geothermal reservoirs of water with temperatures greater than 360°F (182°C). This very hot water flows up through wells in the ground under its own pressure. As it flows upward, the pressure decreases and some of the hot water boils into steam. The steam is then separated from the water and used to power a turbine/generator. Any leftover water and condensed steam are injected back into the reservoir, making this a sustainable resource. Binary cycle power plants operate on water at lower temperatures of about 225°-360°F (107°-182°C). These plants use the heat from the hot water to boil a working fluid, usually an organic compound with a low boiling point. The working fluid is vaporized in a heat exchanger and used to turn a turbine. The water is then injected back into the ground to be reheated. The water and the working fluid are

First of all, harnessing geothermal energy does not have the devastating impact on climate change like burning of the fossil fuels does. It is true that fluids drawn from the earth's core include greenhouse gases such as carbon dioxide and methane, but the amount of released greenhouse gas emissions is negligible compared to those from fossil fuel fired power plants.

   Solar energy is our birthright like the air we breathe or the water we drink. Solar Home Plans and  cost effective   Solar Hot Water Projects  are the gateway into a "Solar Age"  of energy independence. Fossil fuels are no longer necessary to keep the wheels of civilization turning. Build your own solar heating system.  Explore the Strawberry Fields Book Store  for more information. Alternative energies like solar energy will increase in value as fossil fuel prices escalate making energy efficient,  solar houses more valuable. Solar collectors, solar hot water systems, heat storage vaults, photovoltaic electricity, solar panels, and solar greenhouses will soon become the standard rather than the exception to the standard in the near future According to Buckminster Fuller "We have wondered too far from the roots." An energy crisis can only be avoided only if we learn to rely on a diffuse, sustainable resource like the sun. Become part of this green economy and travel on the  Green Train and learn about Solar Rebate Incentives and Cheap Electricity

Brief History of Tidal Power The energy stored in tides been known to people for many centuries. The earliest records of tidal mills are dated back to the 8th Century CE.7 The tidal mills were mainly used for grain grinding and were of similar design to the conventional water mills with the exception of the addition of a dam and reservoir. The industrial revolution increased demand for power but tidal energy never got off the ground, undercut by cheap fossil fuels and other developments which offered easier access to power generation. Existing tidal mills became as obsolescent as pre-industrial water-mills. The first large scale modern tidal electric plant started to operate in La Rance Estuary, St. Malo, France in the 1960s and has been operating ever since. In recent years the search for renewable, non-polluting energy sources and the increase in fossil fuel prices has encouraged renewed interest in tidal power.

Bio fuel is a natural alternative from other fossil fuels and is attained from living or biological material that has just died. Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth. To assist in the manufacturing of biofuel, the plants and plant-derived materials that contribute to its formation includes corn, corn cob, sugar cane, soybeans, flaxseed, rapeseed, vegetable oils, waste cooking oils, animal fats, tall oil and even cow manure. However, at present the most widely used source of bioeenergy is of course wood.
