  • Renewables overtaking fossil fuels in new power generation

    Renewable energy has surpassed fossil fuels worldwide as the main source of new electricity generation, the latest report from the International Energy Agency has found.

    The premier global energy research group warned that demand for coal is set to slump if the world is to achieve its commitment to limit global warming.

          IF you have Google Earth type in Dolan Barracks. A post that use to be home that Germany got when we left. Now look around and see if you can find more than one solar panel. Well one thousand might be closer.

            Demand for solar panels is booming where I live, the guys installing them canít keep up. Our last house had solar panels, our power bills went down by up to 70%.

              Don't you need a lot of Sunny Days to get that kind of result? There is also the problem of non production at night. I did some looking into wind turbines years ago and there was a problem with whether or not the local utility would buy the excess electricity produced at night when household use of electricity was minimal.

                Try to heat your house with solar panels North of Kansas.

                It isn't growth that matters but costs plus the subsidizes, the percentage of current use and the fact that conventional energy sources are already built and penalised by government regulation leaving little room for normal market forces.

                The people that are being punished by alternative energy are the poor not the upper middle class. Not only do they not live where it is practically they can't afford it. That will change as cost come down but it is something to consider.

                Reducing demand for centralized energy may be wonderful thing but not if it means the infrastructure for industrial uses is not maintained. The timing is especially bad when for strategic reasons we need to compete with China.

                This a complex subject that requires careful analysis. It doesn't hurt to listen to Doc even if you don't agree.

                  Naturally, but in the summer time isnít the best time either. Solar panels lose efficiency once they get too hot, itís a culmination of many things that makes it work, we didnít get the panels installed and expect it to perform miracles.
                  The price of power here is forcing many to buy panels.
                  Anyway, our new home keeps the heat out in summer, plus we upgraded our hot water system to something much more efficient. That alone has saved us many dollars, and we donít have solar panels yet... may not need them either if the efficiency measures we have already implemented work as expected.

                    According to 'Data' all other non-renewables combined, have finally caught up with Hydro power which is difficult to expand.

                    Also note that in only 11 years, fossil fuels made up as much power production as ALL sources from 2006.

                    Until the rate of yearly increase in power demand is exceeded by only renewables, production of fossil fuels will continue to increase.

                      You live in friggin' Oztraileeya. Of course solar makes some sense. Not so much in cooler more cloud laden climes. Here the rage is all about replacing one fossil fuel, coal, with another, natural gas. Local power company finally is given the go ahead for a new nuke, but said, "thanks, but we are going to LPN now, and oh, btw, we don't want to pay taxes anymore for nuke and coal plants." Can't wait until gas prices for heat etc goes through the roof. Don't expect Edison to lower rates with the cheaper fuel either.

                        There's an "Achilles Heal" with regard to "renewable energy";

                        We Don't Mine Enough Rare Earth Metals to Replace Fossil Fuels With Renewable Energy

                        Rare earth metals are used in solar panels and wind turbinesóas well as electric cars and consumer electronics. We don't recycle them, and there's not enough to meet growing demand.

                          But, the price of electrical power is so high in Oz due to the push by the government for more wind and solar. That is, wind and solar are driving the prices up to a point where individuals are investing in home solar to avoid the high cost of commercially produced solar.

                          I don't know what kind of government subsidies are offered there, but in the US essentially you are paying now for the next 15 to 20 years of electrical power you will consume by having home solar installed.

                          Worse, in California they're now going to mandate all new homes built have solar installed. This is expected to drive the price per home up between $8,000 and $12,000 which is sufficient to price between half a million and a million home buyers out of the market.

                          All this will do is drive the price per KWH up for commercial power more than it already has.

                            Renewables have dropped the wholesale price, but the reliance on gas generation has driven up prices. The federal government is clinging to coal because of nice political donations, but the rest of us are moving on and doing something productive and cheaper for the long term.

                              In Germany, who like Oz, where solar has taken over a large part of the market, the commercial price has risen substantially due to the variability of solar power delivery. Too much solar being delivered forces conventional plants off line at serious cost, particularly large coal and oil fired ones. Idling a coal plant that takes days to start up or shut down is a tremendous cost.
                              Then there's the amount of power delivered. It can often be more than the market can bear so the price is driven into the negative. Power companies make up the loss by charging more other times when there is a shortage.

                              Using solar for base loading and having more than about 15% solar in your energy mix is a sure way to drive electrical prices sky high as has happened in Germany, Spain, Italy, and Australia.
