  • Green energy has never been more important than it is today with the looming threat of global warming. Every possible effort must be made to reverse the worldwide threat of climate change by subsidizing and switching to green energy. One often-overlooked source of clean, renewable energy comes not from solar, wind or geothermal power, but from the tides.
  • Tidal Energy is valuable to environmentalists because unlike fossil fuels the source of energy will not be depleted in the foreseeable future no matter how much energy is collected.
  • The collection of tidal energy is clean because it involves very little emission of carbon dioxide and other greenhouse gases
  • ...3 more annotations...
  • The pattern of tides is extremely stable and not strongly affected by weather conditions which suggests that it would be a very stable source of green energy.
  • Moving water can exert a much greater force on a turbine than wind which means the turbine can turn slowly and still produce a great deal of electricity. The slow and stable tidal forces are ideal parameters for engineering energy solutions. The fact that the turbines can be slow-moving makes it easier to avoid interfering with local ecosystems
  • While the initial cost of building tidal energy plants is high, the plants are expected to run for a very long time which will make them more cost-effective in the long run

Green energy has never been more important than it is today with the looming threat of global warming. Every possible effort must be made to reverse the worldwide threat of climate change by subsidizing and switching to green energy. One often-overlooked source of clean, renewable energy comes not from solar, wind or geothermal power, but from the tides. 1. Tidal Energy is Renewable Tidal Energy is valuable to environmentalists because unlike fossil fuels the source of energy will not be depleted in the foreseeable Future no matter how much energy is collected. The gravitational relationship between the Earth and the moon is extremely stable in the long term just like solar, wind and geothermal energy. 2. Tidal Energy is Green The collection of tidal energy is clean because it involves very little emission of carbon dioxide and other greenhouse gases. However, the marine ecosystem is fragile and great care must be taken to avoid interfering with the lives of organisms that depend on the tide."

shared by dpurdy on 03 Nov 11 - No Cached
  • Hydrogen as the Main Fuel of the Future Over the last decades hydrogen, (H2) has gained more and more attention as an environmentally friendly fuel and storage medium. Combustion of pure hydrogen produces only water as exhaust. Hydrocarbon and carbon oxide emissions can only come from motor oil in the combustion chamber. Nitrous oxide emissions result from the nitrogen content in the air and increase exponentially with the combustion temperature. By using H2 in fuel cells, practically no pollution occurs. In this respect, hydrogen offers emission levels that are much lower than existing and Future standards.
  • Hydrogen is the most common of all elements in the universe.
  • The desire for a long-term transition to a hydrogen society is mainly based on the need to reduce polluting and climate-affecting emissions and the concern about depletion of fossil fuel resources. Today about 90 % of the world's energy consumption is covered by fossil fuels, and most of this comes from a limited number of regions in the world. Even if hydrogen will be used on a large scale in the future, there is still a need for an energy source to produce it. Renewable energy technology such as hydro electricity, wind, wave and solar power are in principle available, but are not yet mature for mass production and/or fully developed.

  • Future Of Geothermal Energy The Future of geothermal energy depends on three factors: it's demand, supply and it's competitiveness among other renewable resources in terms of cost, availability, reliability etc.. Demand for geothermal energy is going to increase and increase with the increase in the population and extinction of other non-renewable sources. Moreover, today government also support the resources which are cleaner and do not spoil the environment. Supply of geothermal energy is limited and confined to certain areas only.

shared by faglejoh98 on 08 Mar 13 - No Cached
  • Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth's internal heat.This thermal energy is contained in the rock and fluids beneath Earth's crust. It can be found from shallow ground to several miles below the surface, and even farther down to the extremely hot molten rock called magma.These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.A geothermal heat pump system can take advantage of the constant temperature of the upper ten feet (three meters) of the Earth's surface to heat a home in the winter, while extracting heat from the building and transferring it back to the relatively cooler ground in the summer
  • There are three types of geothermal power plants: dry steam, flash, and binary. Dry steam, the oldest geothermal technology, takes steam out of fractures in the ground and uses it to directly drive a turbine. Flash plants pull deep, high-pressure hot water into cooler, low-pressure water. The steam that results from this process is used to drive the turbine. In binary plants, the hot water is passed by a secondary fluid with a much lower boiling point than water. This causes the secondary fluid to turn to vapor, which then drives a turbine. Most geothermal power plants in the future will be binary plants.
  • It can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces.

Wave Energy: an Overview (Oxfordshire Climate Exchange) - 1 views

climatex.org/...wave-energy-overview wave potential future how form history
shared by dpurdy on 30 Oct 12 - No Cached
  • Waves are generated by winds blowing over the ocean surface.  Wave energy is effectively a stored and concentrated form of solar energy since the winds that produce them are caused by pressure differences in the atmosphere caused by the sun's differential heating of the earth's surface. Waves can efficiently transport energy for thousands of miles and retain their energy long after the winds that first created them have died down, which makes waves one of the most concentrated and consistent sources of renewable energy. 
  • Globally, the potential use of wave power is, unsurprisingly, limited to areas of the world where there are waves. On a global scale, this is dictated by global wind patterns, with the result that waves are more prevalent in the mid-latitudes (40-60(N/S), than nearer the equator where the lack of ocean wind is referred to as the 'doldrums'.  Interestingly, this potential for wave power contrasts with that of solar power, which is more effective in lower latitudes

    Challenges Producing hydrogen in the large quantities necessary for the transport and stationary power markets could become a barrier to progress beyond the initial demonstration phase.  Uses: Fuel cells will be used in a wide range of products, ranging from very small fuel cells in portable devices such as mobile phones and laptops, through mobile applications like cars, delivery vehicles, buses and ships, to heat and power generators in stationary applications in the domestic and industrial sector. Future energy systems will also include improved conventional energy converters running on hydrogen (e.g. internal combustion engines, Stirling engines, and turbines) as well as other energy carriers (e.g. direct heat and electricity from renewable energy, and bio-fuels for transport).

  • Cellulosic ethanol could raise per acre ethanol yields to more than 1,000 gallons, significantly reducing land requirements. Cellulosic ethanol is made by breaking down the tough cellular material that gives plants rigidity and structure and converting the resulting sugar into ethanol. Cellulose is the world’s most widely available biological material, present in such low-value materials as wood chips and wood waste, fast-growing grasses, crop residues like corn stover, and municipal waste.

  • Engineered geothermal systems (EGS) are based on a related principle, but they work even in parts of the world that are not volcanically active, by drilling thousands of metres underground to mimic the design of natural steam or hot-water reservoirs. Wells are bored and pathways are created inside hot rocks, into which cold water is injected. The water heats up as it circulates and is then brought back to the surface, where the heat is extracted to generate electricity. Because the Earth gets hotter the deeper you drill, EGS could expand the reach of geothermal power enormously and provide access to a virtually inexhaustible energy resource.

  • When looking at a wind powered electric generator, many people see a permanent source of renewable electricity. The problem with this image is that wind generators have shorter life spans than the term “sustainable” would imply. Wooden windmills in Holland that used to power industrial machinery before the invention of steam engines were more durable than these picket lines of propellers along our Columbia Gorge. The composite material and rare earth chemicals they require are both perishable and costly to replace. More important, like fossil fuels, our planet has a finite supply of these materials. Wind power is such an inefficient means of generating electricity that a world that seriously relied on it the way we do fossil fuels would run out of the limited resources needed to build and maintain them long before our present trends would exhaust our vast bounty of hydrocarbons.

    "The first hard core environmentalist I ever encountered in life taught my 8th grade energy class at Estacada Junior High, a course that President Carter's brand new Department of Education had mandated upon us a decade before as a symbolic gesture to show he cared about America's energy future. Despite an overall policy of separating church and state, in this class it was the gospel that we would deplete all fossil fuels by the year 2000. Back when "2000" was preceded by "THE YEAR" it seemed so far away didn't it? The only lasting lesson this course taught me was a healthy skepticism of government mandated indoctrination."
