Wind Power To Feature Heavily In World’s Energy Mix

Wind energy outlook

Wind power could provide 20 percent of the world’s electricity supply by 2030 as nations begin curbing carbon emissions in line with commitments made at last year’s Paris Climate Summit.

According to a new report from the Global Wind Energy Council (GWEC), big decreases in the price of renewable energies like wind and solar over recent years have made these technologies economically attractive in most markets, with wind power in particular expanding rapidly in emerging nations.

The Council’s biennial Global Wind Energy Outlook outlines four scenarios for the future of wind in the world’s energy mix out to 2020, 2030 and 2050.

Under the Advanced Scenario, wind capacity could reach a total 2,110 GW by 2030; supplying up to 20 percent of global electricity; creating 2.4 million new jobs and reducing global carbon dioxide emissions by more than 3.3 billion tonnes per year.

Under this scenario, annual global wind investment would total about €200 billion (~ AUD $285 billion).

“Now that the Paris Agreement is coming into force, countries need to get serious about what they committed to last December,” said Steve Sawyer, GWEC Secretary General. “Meeting the Paris targets means a completely decarbonised electricity supply well before 2050, and wind power will play the major role in getting us there.”

In its report, the GWEC uses the different scenarios to explore the future of wind power in a decarbonised world. The baseline model is the International Energy Agency’s New Policies Scenario (NPS), based on national and international emission reduction targets adopted during the Paris talks (COP21) in 2015.

The NPS is set against the IEA’s 450 Scenario, which outlines a solely supply – rather than policy – based approach to limiting a global temperature rise of 2 degrees Celsius by halting the concentration of greenhouse gases in the atmosphere at 450 parts per million carbon-dioxide equivalent (ppm CO2-eq) in the long-term.

The GWEC’s Moderate Scenario uses the much the same baseline criteria as the IEA’s NPS, and assumes most governments have enacted the renewable energy and carbon reduction policies agreed to at COP21, albeit at a modest level. Out to 2020, the Moderate Scenario modelling coincides neatly with annual market forecasts for growth in the wind energy sector, before global uncertainties make accurate price forecasting impossible.

The Advanced Scenario is the most optimistic model, and assumes total commitment to renewable energy targets and industry recommendations by governments. It also assumes a universally agreed objective of keeping global mean temperature rise below 2°C above pre-industrial temperatures.

“Wind power is the most competitive option for adding new capacity to the grid in a growing number of markets,” said Mr Sawyer, “but if the Paris agreement targets are to be reached, that means closing fossil fuel fired power plants and replacing them with wind, solar, hydro, geothermal and biomass.”

“That will be the hard part,” he says, “and governments will have to get serious about it if they are to live up to the commitments to which they have now bound themselves.”

Residential Wind Turbine: 3 Reasons It Will Always Work

With home energy prices going through the roof in many cases, it is only natural that people would start seriously considering residential wind turbine power as a way to hedge against those price increases.

There are 3 distinct advantages that residential wind turbine power has over the rest of the options out there and this is why it will always work, regardless of what other forms of power generation become available in the future…

Clean energy with no pollution – We often forget about the fact that renewable energy sources do not create any pollution. Not only do they not create pollution by the power that they make in the way that they make it, but also by the fact that when you use renewable energy you are not having to buy power from a facility that is making it using carbon-based fuels, like fossil fuel power.

Pollution is a huge problem in many areas of the world. In our largest cities, pollution is a daily fact of life that is being dealt with on many fronts. By focusing on wind energy and other renewable sources we have the potential to displace a large portion of the power that we now buy from smoke emitting power plants and replace that with clean energy that happens to also be free.

Intermittent source, but the power created can be stored – It goes without saying that renewable energy sources are intermittent. That just goes with the territory-if the sun is not shining and the wind is not blowing there is no way to extract power from either of those sources. However, our compensation mechanism is the battery. Battery systems attached to home wind turbine products allow them to store energy during times when power cannot be created from the wind real-time.

Wind will always blow – This is the greatest thing about the renewable energy product. The wind is always available to blow and make power for you at least to some degree at some time of day. Even if it is a very low velocity, the wind is available. It might be diffused and not visible if you are talking about an area very close to your house. However, make no mistake about it, there is wind available the higher up you go. As you get over the tree line for example, wind is almost always available.

In summary, residential wind turbine strength will provide lots of power for homeowners for years to come.
