They ' re told it ' s satellite towards the end of the video . <| sep |> I went in for the event having never played HotS or any MOBA before . I liked the game , finished the 30 wins nexus quest to get a whole stack of heroes , got Raynor and Sylvanas for using someone ' s recruit code , bought Valla for kicks , and currently have around 25 k gold to buy whatever . I ' ve been playing the game less than a week . <| sep |> That ' s right , I ' m going to fuck the fearturkey . <| sep |> Oil power plants run at maybe 45 % efficiency , ignoring the processes required to deliver it to site extraction , transportation . This is on par with ~ 4050 % coal efficiency depending on method of combustion . This is a good sight higher than what you ' ll find for wind ~ 25 % efficiency and photovoltaics ~ 15 % efficiency , absolutely , and photovoltaics in particular have their own challenges finding the silicon for the cells . Progress is being made , however , in terms of photovoltaics I think the current record is around ~ 35 % efficiency , but that isn ' t in process of being massproduced . But the question at this point cannot just be what is more efficient . We also have to evaluate the remaining resources generous estimates put fossil fuels at lasting another 300500 years , but that assumes current levels of use , along with the harm all of those pollutants are causing to the environment , which is formidable . Fossil fuels are a great solution to a shortterm problem and a fucking terrible obstacle to the longterm stability of our species .
