RE: Solar Panels To Be Twice As Efficient With This New Groundbreaking Technological Innovation (News In Science & Technology)
I think he is a bit too optimistic. I don't think is technically feasible with technology such as solar panels, but we certainly, already have capacity to cover all current and future world's energy needs with renewables, if we combine all geothermal, solar, tidal, wind and hydroelectric power together. We already have the means and know how.
The only thing, which is stopping uss from achieving this is a consolidation of power in fossil fuel industry. There is more profit in being ecologically unsustainable.
Solar could easily power the entire world's needs w/o other technologies, how is it not feasible? You think we'd run out of space to put panels??
Yes, the space is a major issue. There is limited amount space which is sunny enough and which is not used not used for crops, livestock grazing or as wildlife reserve. Some countries have more of such space than others. Some countries have none. Anyway, there is no reason to rely on only one renewable source, when we have so many options. Renawables should be chosen according to local environmetnal factors. In one area it is mroe efficient to build geothermal power plant, while in other solar based or wind based etc.
