    WIND ENERGY is extremely efficient

    Wind energy on a lifecycle basis takes about 5 to 6 months to return the total energy expended

    An evidence review published in the journal Renewable Energy in 2010, which included data from 119 turbines across 50 sites going back 30 years, concluded that the average windfarm produces 20-25 times more energy during its operational life than was used to construct and install its turbines. It also found that the average "energy payback" of a turbine was 3-6 month

    Uruguay shows renewable energy can be achieved by direct government action

    In the last 10 years, Uruguay has shifted dramatically to electricity generated from renewable sources and shifted away from petroleum-based generation. Currently 98 to 100 percent of electricity comes from renewable sources compared to just 40 percent as recently as 2012.

    So is the government going to get directly involved in Alberta and make the wind blow? Fml

      Alberta
      Now some wind companies say they've brought generation costs down to between 2 and 4 cents — something that appeals to provinces that are looking to significantly increase their renewable energy.

      The cost of electricity varies across Canada, by province and time of day, from an average of 6.5 cents per kWh in Quebec to as much as 15 cents in Halifax.

      Capital Power, an Edmonton-based company, recently won a contract for the first phase of the Whitla wind project near Medicine Hat, Alta., with a bid of 3.9 cents per kWh and capacity of 201.6-megawatt (MW). That price covers capital costs, transmission and connection to the grid, as well as the cost of building the project.

      Saskatchewan
      In Saskatchewan, the plan is to double its capacity of renewable electricity, to 50 per cent of generation capacity, by 2030, and it uses an open bidding system between the private sector generator and publicly owned SaskPower.

      In bidding last year on a renewable contract, 15 firms submitted bids, with an average price of 4.2 cents per kWh.

      One low bidder was Potentia with a proposal for a 200 MW project, which should provide electricity for 90,000 homes in the province, at less than 3 cents kWh, according to Robert Hornung of the Canadian Wind Energy Association.

        The why isn't the entire country side dotted with windmills? Wells are drilled for a million dollars or more just to get 10 or 20 bbls a day out of the ground. Surely windmills can do better than that?

          We could be just like Costa Rica if we had active volcanos like they do to run steam turbines which supply most of the power for the northern part. Locals use very little electricity they have electric ovens but prefer to cook outside with wood why cook in your house then need a ac to cool it down. They all own a nice car and or motorbike and a nice home without AC. The locals go to the market daily and buy their meat and what ever they need for that day so no need for a fridge. November December are the fire months where they burn all the undergrowth in their yards pastures and forests to prevent massive fires like we get in North America and Australia. Totally different country and climate than Canada. You can cook outside almost every day of the year, walk to the market for anything you desire and don’t have to worry about freezing to death for 8 months.

            Reliance on wind energy makes sense in countries with zero oil production and are either forced to import oil or set up wind / solar .
            Not so much for areas that have vast resources of oil / natural gas.
            It will never be a one size fits all situation for either.

              Agree, we have it all in place, cheapest is to USE IT, save the MASSIVE investment cost of turbines/ solar. IMO maintenance will eat up all the savings over time. Real BIG stuff costly to maintain and replace.

                Denmark WIND ELECTRICITY

                Denmark hit a major renewable energy milestone in 2019, producing nearly half of its electricity from wind alone.

                State-run energy operator Energinet announced its new wind record on Twitter Thursday. The renewable energy source now makes up 47 percent of the country’s energy consumption, heating the previous record set in 2017 of 43 percent.

                  Wind energy makes sense in Canada at a generation at a cost of 3 to 4 cents per kWh as the article I posted indicates.
                  What are you currently paying for hydro in Sask and Alberta? cents per kWh?

                    Steam and wind each provide 10% to 15% of Costa Rica electrical power the rest is hydro electricity from dams

                      This is what "you people" want for us? No thank you...3 cents turns into 30 cents, totally uneconomical.

                      "Germans suffer the second highest power prices in Europe, just behind wind ‘powered’ Denmark, and those prices are rocketing north at double-digit rates. The German grid is on the brink of collapse."

                        Wind also has a better fit in a costal location. It is always windy on the coast. Denmark has lots of windmills in the Ocean.

                          So I am curious Integrity Farmer today is the first day out of the last seven that wind power is being generated in any useable amount in Alberta due to the lack of wind for the previous six days, so in that context does it matter what it costs to generate when there is none to buy?

                            Three windmills around here. All are STOPPED. Guess why? Wind is not a constant speed and ice forms on the blades. Both perils destroy them.

                              Agree .
                              What’s the power demand in Denmark per household when they are 40 below with now wind?
                              Just asking for a friend...

                              Also the incredibly consistent trade winds from the ocean in and around Denmark...... well that’s non existent in Sask and Alberta .
