geothermal co2 fossil fuels

  • bounadaries and faults are cracks in the Earth’s crust where magma rises near or to the surface. Geothermal plants take advantage of this fact using water heated by this volcanic activity to produce electric power.
  • The best part is that it is clean energy. There is no way it can produce pollution that can harm the environment

  • People have harnessed the tides and used its energy for many centuries. Tide mills—which are the precursors to today’s tidal power plants— have great similarity to water wheels. The difference is that water must first be collected from the incoming tide before it can be released to rotate the water wheel.
  • he oldest, excavated tide mill is dated to the year 619.

  • Quick and interesting facts related to solar energy.  For more terms and explanations, consult our solar glossary. One kilowatt equals 1,000 watts. One kilowatt-hour (kWh) equals the amount of electricity needed to burn a 100 watt light bulb for 10 hours. A sunny location (like Los Angeles, California, US) receives an average of 5.5 hours of sunlight per day each year. A cloudy location (like Hamburg, Germany) receives 2.5 hours per day of sunlight each year. A 1 kilowatt peak solar system generates around 1,600 kilowatt hours per year in a sunny climate and about 750 kilowatt hours per year in a cloudy climate. A solar energy system can provide electricity 24 hours a day when the solar electric modules are combined with batteries in one integrated energy system. Solar modules produce electricity even on cloudy days, usually around 10-20% of the amount produced on sunny days. The typical components of a solar home system include the solar module, an inverter, a battery, a charge controller (sometimes known as a regulator), wiring, and support structure. A typical silicon cell solar module will have a life in excess of 20 years Monthly average residential consumption of electricity in the US in 2008 was 920 kilowatt hours. (Source: US DOE) Monthly average residential electricity bill in the US in 2008 was $103.67. (Source: US DOE)

  •    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

wind climate change

shared by carusonepay99 on 12 Mar 13 - No Cached
  • Each year we release millions of tonnes of carbon dioxide by burning fossil fuels (oil, coal and gas). In 2010, on average, every single EU citizen emitted 9.4 tonnes of CO2 – that’s enough to fill ten three-storey buildings. For every kWh of wind energy that you use, you will save approximately 696g of CO2. EWEA estimates that wind energy avoided the emission of 140 million tonnes of CO2 in 2011 in the EU, equivalent to taking 33% of cars in the EU – 71 million vehicles – off the road. This avoided CO2 costs of around €3.5 billion (assuming a price of €25/t CO2). Choosing how your electricity is produced plays an important role in protecting the climate: it’s easy to switch to a green power provider; you request the change and your current and future providers will organise it themselves.

  • It depends what you mean by "solar energy." Humans have always used solar energy in some sense: to warm themselves, to grow food, etc. However, I'm assuming that's not really what you mean (although it is important to realize that all energy on earth, with the exception of nuclear fission and geothermal, is ultimately driven by the sun's energy -- even fossil fuels, which after all were plants that grew with sunlight millions of years ago). Solar power has been used directly in various forms for over 100 years.

  • Ancient Egyptians built places to live that allowed stored energy from the sun during the day, and a heat release during the night. This kind of architecture heated homes at night while keeping the temperature low during the day. Egyptians also used the sun as part of their mummification process, using the sun to dry dead bodies. The Egyptians used a form of passive solar power. 3rd Century B.C., Greek soldiers with the help of Archimedes, focused light on a Roman fleet by using mirrors,

  • Which State do you live in?
  • Federal solar tax rebate
  • most of the cost of your system has to do with where you live.
  • ...11 more annotations...
  • These can be tax write-offs or money back in your pocket.
  • Many states, like New Jersey and Massachusetts, have developed credit markets. You get credits for producing solar and you can sell them for money.
  • if you can cut your power bill before you go solar, everything will cost less. Consider a home energy audit before upgrading to solar energy.
  • Local utilities and municipalities (LA is a great example) have their own solar energy subsidies
  • How much Solar Energy do you Want to Produce?
  • Sometimes just knocking off a part of the bill can give you huge monthly electricity cost savings, as in the case of tiered electricity rates
  • In some areas your utility will pay you for an extra electricity you send back to the grid.
  • importance of energy efficiency
  • If you buy the system you’ll see big up-front costs
  • so you might not get to claim all the credits and rebates available.
  • Generally this option trades long-term financial gain for low (or no) up-front cost.

solar solar power facts

shared by butlerlex99 on 12 Mar 13 - No Cached
  • For billions of years, the sun has poured out huge amounts of energy in several forms, including light, heat, radio waves, and even x-ray. The Earth, in orbit around the sun, intercepts a very small part of the sun’s immense output. On Earth, direct sunlight is available from sunrise until sunset, except during solar eclipses. Solar collectors and modules are designed to capture some of the sun’s energy and change it from radiation into more usable forms such as heat or electricity. In fact, sunlight is an excellent source of heat and electricity, the two most important forms of energy we consume.
