Renewable Energy – Modern Marvels – History Channel Documentary

Posted by admin on April 1, 2013 in Renewable Energy with 24 Comments


Take an in-depth look at the most proven and reliable sources: solar, wind, geothermal, biofuels, and tidal power. From the experimental to the tried-and-true, renewable energy sources are overflowing with potential… just waiting to be exploited on a massive scale.
Global problems require global solutions. Modern Marvels: Renewable Energy, a one-hour History Channel documentary, shows how the combined forces of wind, solar, geothermal, biomass, wave and tidal power are ready to move the world beyond oil, coal and other 19th Century technologies.
Renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables.

The use of wind power is increasing at an annual rate of 20%, with a worldwide installed capacity of 238,000 megawatts (MW) at the end of 2011, and is widely used in Europe, Asia, and the United States. Since 2004, photovoltaics passed wind as the fastest growing energy source, and since 2007 has more than doubled every two years. At the end of 2011 the photovoltaic (PV) capacity worldwide was 67,000 MW, and PV power stations are popular in Germany and Italy. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is the Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugarcane, and ethanol now provides 18% of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar PV systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. United Nations’ Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity. Carbon neutral and negative fuels can store and transport renewable energy through existing natural gas pipelines and be used with existing transportation infrastructure, displacing fossil fuels, and reducing greenhouse gases.

Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing Renewable Energy legislation, incentives and commercialization. New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors. According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world’s electricity within 50 years, dramatically reducing the emissions of greenhouse gases that harm the environment.

    you are correct, i know alot of people who think it is fake. Listen, i’ve been getting paid about $200 a week just for letting brands know what i prefer to buy. i got it from here. you can also try it: bit.ly/13Jv4J9?=epfsz

    Who cares when the …
    Who cares when the return on investment for solar is? the mere fact that we are talking about return on investment should be all the information we need to make the investment. Now if we can get it to a point where we we can procure and install it ourselves without being penalized by the utility company, then we would be getting somewhere.

    “The dark side of solar cells” well thanks but I think I give it a miss this once. I’m not interested in anti solar cell propaganda. you will find many things on the internet and I don’t give a about most of these. there is nothing wrong with solar cells. you shouldn’t google so much conspiracy theory stuff. luckily I know how they are produced and it’s quite simple and strait forward. some sand and energy. the cell produces the same amount of energy we needed to produce it within 1,5 years

    I will however keep a close interest in the development of PV cell technology because I would certainly like to reduce my monthly energy bill.

    Google The dark side of solar cells. Most comments claim that the ROI time is more than 3 years, some even claim up to 10 year if one adds the battery that should go with a PV cell. Cell manufacturers’ data are most often obtain from Equatorial locations and cell output generated round about noon.

    whats the point ? every1 knows we can get power from this .but still they dont make it ..just think what would happen if every home uses its own produced power ? or every car running on its on solar panel on the roof ? what would happen to the big oil companies ???

    It would have been even a better idea if they could transfer the water vapor into liquid form for other use. Water vapor is also not good for the environment.

    EAWC TECHNOLOGIES Solutions

    EAWC Technologies was created to respond to the growing need in drinking water and proposes a water purification solution utilizing solar, photovoltaic energy and, when applicable, a mini-windmill or an alternate source of renewable energy. From the sea, lake, river or stagnant, water is passed through several stages of purification and treatment until it is rendered drinkable as per World Health Organization standards.

    that is not true. a …
    that is not true. a solar cell returns the the energy used to produce it within 1,5 years. they can have lifespans of well over 30-50 years and longer. actually they never stop they just get less efficient over time because of radiation and scratches on the glas suface depending where they are installed. there is no oil used in the production of silicium wavers only silicium, some chemicals who are recycled (closed loops) and very few secondary oils for lubrication of the machinery.

    They have snow in Germany as well. You still have the grid.

    Think …
    Think decentralization of solar, so that it gives money & power to the 99%.
    This film wants to trick you into thinking only big corporations can do this.
    It is inevitable that every home in the future will make enough money to pay for your mortgage & solar panels over 50 years.
    Yes, panels last 50 years.

    A 19 yr old German college student, Hermann Scheer, drafted the original solar feed in tariff in 1980. By 1990 anyone in Germany could make $0.54 kwh by harvesting solar & feeding the grid. Read his books: “Energy Imperative”.

    Germany will …
    Germany will achieve 100% solar & renewables by 2030.
    Japan will achieve 100% renewables by 2041.
    I am doing a documentary film on Japan’s race to 100%.

    OK, but this …
    OK, but this misses the main point of solar.
    Everyone can make big money selling solar onto the grid.
    By putting solar on every home, where it is needed, we save transmission loss.
    By having a solar feed in tariff requiring Utilities like PG&E to pay homeowners $0.54 kwh for feeding solar onto the grid.
    This pays for the cost of the panels in 5 years.

    In Germany homeowners make up to $60,000. a year from feeding solar onto the grid.
    LA just passed a feed in tariff.
    Vermont has one.

    Photovoltaic cells …
    Photovoltaic cells are a hoax in terms of reducing carbon emissions. More carbon dioxide are produced during the manufacturing of the silicon in a solar cell than the amount of carbon that cell will save during its lifetime. CIGGS cells are still experimental and commercially it is only silicon based cells that are available.
