  • The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the oceans via wave power.
  • Wave energy is generally considered to be the most concentrated and least variable form of renewable energy. It is the high power density of wave energy that suggests it has the capacity to become the lowest cost renewable energy source.
  • Wave energy is a renewable, zero emission source of power

  • Except for South Korea,not other government in the world is really pushing Tidal Wave Energy which needs massive government support at this stage of development.
  • Tidal Technology is still in the baby phase
  • Most of the tidal power plants using the modern tidal turbine technology are still in the pilot phase and generate negligible power.However tidal power stations have the potential to generate large amounts of energy in a non-polluting way

  • There are over 180,000 fueling stations nationwide. About 40% of those service petroleum diesel fuel, and less than 1% service biodiesel.
  • Biodiesel is simple to use and requires no costly engine conversions or infrastructure changes to the current delivery system of diesel fuel.

  • ) systems. This was double the 435 MW installed in 2009 around the U.S.[16] According to a 2011 survey conducted by independent polling firm Kelton Research, nine out of 10 Americans support the use and development of solar technology. Eight out of 10 respondents indicated that "the federal government should support solar manufacturing in the U.S. and should give federal subsidies for solar energy".[17] According to the Energy Information Administration, in 2010, subsidies to the solar power industry amounted to 8.2% ($968 million) of all federal subsidies for electricity generation.[18] Solar Energy Industries Association and GTM Research found that the amount of new solar electric capacity increased in 2012 by 76 percent from 2011, raising the United States’ market share of the world’s installations above 10 percent, up from roughly 5 to 7 percent in the last seven years.

  • Biodiesel is considered a non-flammable and non-combustible product.
  • Optimally, dedicated biodiesel tanker trucks and associated transfer components should be used to transport biodiesel. If non-dedicated equipment is used, it must be washed, rinsed, drained and dried prior to biodiesel loading in order to avoid any cross-contamination.

  • Bio fuels are a viable alternative to fossil fuels.
  • Some examples are that of biodiesel, which entails growing crops that contain high amounts of natural oil then through a process of hydrogenation or refining a more compatible bio diesel, substitute is created.
  • These are examples of first generation biofuels and due to their nature they may or may not be long-term economically or environmentally viable.

  • The major challenge to using wind as a source of power is that it is intermittent and does not always blow when electricity is needed. Wind cannot be stored (although wind-generated electricity can be stored, if batteries are used), and not all winds can be harnessed to meet the timing of electricity demands. Further, good wind sites are often located in remote locations far from areas of electric power demand (such as cities).
  • Although wind power plants have relatively little impact on the environment compared to fossil fuel power plants, there is some concern over the noise produced by the rotor blades, aesthetic (visual) impacts, and birds and bats having been killed (avian/bat mortality) by flying into the rotors. Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants.

  • A Renewable Non-Polluting Resource Wind energy is a free, renewable resource, so no matter how much is used today, there will still be the same supply in the future. Wind energy is also a source of clean, non-polluting, electricity. Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases. According to the U.S. Department of Energy, in 1990, California's wind power plants offset the emission of more than 2.5 billion pounds of carbon dioxide, and 15 million pounds of other pollutants that would have otherwise been produced. It would take a forest of 90 million to 175 million trees to provide the same air quality.
