    "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."

    "Archaeological evidence shows that the first human use of geothermal resources in North America occurred more than 10,000 years ago with the settlement of Paleo-Indians at hot springs. The springs served as a source of warmth and cleansing, their minerals as a source of healing. While people still soak in shallow pools heated by the earth, engineers are developing technologies that will allow us to probe more than 10 miles below the earth's surface in search of geothermal energy. We invite you to study the timeline of the recent history of geothermal energy in the United States."

  • Biofuels in the solid form has been in use ever since man discovered fire.
  • Wood was the first form of biofuel that was used even by the ancient people for cooking and heating
  • This form of fuel was discovered even before the discovery of the fossil fuels, but with the exploration of the fossil fuel like gas, coal, and oil the production and use of biofuel suffered a severe impact.
  • ...2 more annotations...
  • One of the first inventors to convince the people of the use of ethanol was a German named Nikolaus August Otto. Rudolf Diesel is the German inventor of the diesel engine. He designed his diesel engine to run in peanut oil and later Henry Ford designed the Model T car which was produced from 1903 to 1926. This car was completely designed to use hemp derived biofuel as fuel
  • n the period of World War II, the high demand of biofuels was due to the increased use as an alternative for imported fuel. In this period, Germany was one of the countries that underwent a serious shortage of fuel. It was during this period that various other inventions took place like the use of gasoline along with alcohol that was derived from potatoes. Britain was the second country which came up with the concept of grain alcohol mixed with petrol

    "China has also laid claims to having invented windmills around 2,000 years ago, but the first documented claims appear in the 1200's. Around 250 A.D. the Romans introduced windmills into their culture and in the 700's so did Afghanistan. The Afghanistan windmills were also of the vertical axis style and cloth sails or reed matting was developed to catch the air. These windmills were used to grind corn and sugarcane plus draw water. In the 13th century Holland started developing large horizontal axis windmills. These four-blade windmills were larger, carried more torque and wind speed and could do more work than other windmills previously designed. The Holland windmills were also being used to grind grains and to drain part of the Rhine River. In the 19th century Denmark had an estimated 2,500 windmills and in the U. S. windmills were starting to be used to pump water. The Halladay windmill of 1854 is one such example of this. The first windmill in the world built for electrical production was in 1887 in Scotland built by Professor James Blyth. A year later in 1888 in the U. S. Charles Brush of Cleveland, Ohio built a large wind turbine used to generate electricity."

  • his is somewhat balanced out by long plant lives of 100 years for the actual barrage structure, and 40 for the equipment, as well as low operating costs.
  • An estimate is given by researcher Eleanor Denny. Denny estimates that in order for a facility to be profitable, its capital cost should be less than €530,000 (~$700,000 USD) per MegaWatt which with the current technology is not a realistic goal, meaning that so far the industry produces negative net benefits.50
  • Canada's Race Rocks site, where a single turbine generator converts 65 kW of energy, cost $4,000,000.54 This figure was met with $3,000,000 investment from project partner EnCana's Environmental Innovation Fund, and a grant of just under $1 million awarded to Pearson College and their partners in the project.

  • This plant produces about 100 times the power generated at Race Rocks. An investment of around €8.5 million ($11 million USD) made SeaGen a reality.
  • The environmental impacts of tidal barrage include hampered fish migration, forced water level changes on the basin behind the barrage, reduced salinity in the basin due to low quantities of ocean water, and reduced ability of currents to transport and suspend sediments
  • sustainable energy resources produce limited amounts of carbon dioxide emissions
  • , they are, by nature, reliant on the natural environment and therefore are vulnerable to the effects of climate change
  • 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.

  • Records of ocean power conversion date back to 900A.D. where the power of tidal movement was used to grind grains. The first modern commercial tidal power was installed off the coast of St. Malo, in Northern France. Installed in 1965, it has been operating continuously since then, producing 240 MW with every tide.

  • The word geothermal comes from the Greek words geo (earth) and therme (heat). So, geothermal energy is heat from within the Earth. We can recover this heat as steam or hot water and use it to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. ... Cancel

  • Sailboats and sailing ships have been using wind power for thousands of years, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came somewhat later in antiquity. The windwheel of the Greek engineer Heron of Alexandria in the 1st century AD is the earliest known instance of using a wind-driven wheel to power a machine.[15][16].

  • Fueling up with ethanol and vegetable oils  was common long before the development of the internal combustion engine. Vegetable and animal oil lamps have been used since the dawn of civilization. Increasingly efficient heaters and lamps meant that higher quality fuels were developed.  For example, small alcohol stoves (also called “spirit lamps”) were commonly used by travelers in the 17th century to warm food and themselves. One of Ben Franklin’s spirit lamps is on display in a Philadelphia exhibit.

  • At the end of WWI, gasoline quality was declining, and Detroit dropped the standard compression ratio to 3.8 to one. According to Scientific American in 1919, there were to options. One, lower the compression ratio even further, sacrificing efficiency but allowing the continued use of low-grade petroleum.  Or two, use more ethanol in the fuel mix in order to conserve petroleum and allow the creation of more efficient, higher compression engines.  The choice was further skewed in the direction of ethanol when the US Geological Survey announced, in 1920, that oil was running out.[20]

    "Around the 1850s, lamp fuels in the US and Europe were usually made from animal and vegetable oils, often combined with alcohol.  "Camphene" (a camphor oil scented blend of turpentine and ethanol) was by far the leading fuel in the US with at least 90 million gallons sold per year.[14] But a tax on all alcohol in the US, including industrial alcohol for lamps, meant that other sources of illuminants were needed.  The kerosene industry arose as a direct result of this tax on its competitor - and not because whales were running out, as the "whale oil" myth would have it. "Kerosene" was named as the solar (keros) fuel in imitation of  "camphene." The highly volatile byproduct, called "gasoline" in the hope it would be used in municipal gas light systems, was usually blended unsafely into lamp fuels, or just poured into streams or burned off."

  • Hydrogen is colorless, odorless, tasteless and non-toxic. It is a gas at temperatures above -423° F and is highly diffuse, having a density approximately 14 times less than that of air. Because it is buoyant and diffusive, hydrogen dissipates quickly in open areas and can move through small spaces, which makes it difficult to store. Hydrogen is flammable over a broad range of gas concentration (from 4 to 74 percent), although its lower flammability limit – that is, the lowest temperature and pressure at which it will combust – is higher than those for some common fuels such as gasoline, propane or diesel.1 Hydrogen has been described as “the fuel of the future.” On Earth, hydrogen is found in combination with other elements such as carbon (hydrocarbons), oxygen (water) and nitrogen (ammonia). Although hydrogen may sometimes be used as a fuel, it is most often used as an energy carrier, such as electricity, and not an energy source. To make hydrogen a usable, stand-alone fuel, it must be separated from these other elements by chemical, thermal or electrochemical processes.
  • History British scientist Henry Cavendish identified hydrogen as a distinct element in 1766. Subsequent experiments by British and French scientists resulted in the first flight of a hydrogen balloon and the discovery that applying electricity to water can produce hydrogen and oxygen.
  • In the 1960s, NASA space capsules used hydrogen fuel cells for onboard electric power, heat and water.
