Scotland Wind Power: 106% Electricity Demand from Wind

by John Brian Shannon

Last Sunday, in the midst of gale force winds, wind farms generated 106% of Scotland’s electricity demand. It wasn’t the first time and it won’t be the last time.

On many other occasions Scotland produces prodigious amounts of electricity via wind power and with more wind turbines being installed every year we should expect this to become a normal occurrence.

“Turbines spread across the land and in the ocean surrounding Scotland provided 39,545 megawatt-hours (MWh) of electricity to the National Grid on Sunday while the country’s total power consumption for homes, business and industry was 37,202 MWh.

Scotland’s goal of generating 50% of their annual electricity from renewables is on pace to happen a full year early. Scotland also has a goal of 100% renewable electricity by 2020, but it might only get to 87% per some reports. Still – 87% over the course of a year is a powerful value and will probably mean 100% will arrive before 2025.” — Electrek

Both hydro-electric dams and wind turbines in Scotland rely on electricity storage in the form of pumped storage — water pumped back up the hill into the reservoir, allowing that energy to be harvested again.

During the nighttime, wind flow across both ocean and land are more constant than during the daylight hours. Conveniently, this is also when electrical demand is lower, allowing surplus electricity during those hours to pump the water back into the reservoir and ready for the sudden demand spike at 7:00am the next morning.

More pumped storage solutions are planned for Scotland as it’s convenient and (especially over the long term) affordable.

More offshore and onshore wind farms, more pumped storage and more hydro-electric dams means that Scotland may reach it’s goal of 50% renewable energy one year early, while the larger goal of 100% renewable energy by 2020 could take up to 2025 to achieve due to regulatory issues.

Still, that’s an amazing accomplishment by any standard. Hats off to Scotland!

Bill Gates to Unveil World’s Largest Clean Energy Fund

Bill Gates
World leaders will be reportedly looking to reach a consensus on how to enact policies to reduce fossil fuel emissions at the COP21 Climate Summit in Paris. Meanwhile, Bill Gates is leading by example (and not only that) but further donating more billions of dollars towards clean energy research.

Microsoft Corp. co-founder Bill Gates is set to unveil the world’s biggest fund to research and develop clean energy technologies at the Paris Climate Change Summit on Monday, the New York Times reported on Saturday, citing people with knowledge of the matter. The fund is said to include contributions from other philanthropists as well as commitments… Continue reading Bill Gates to Unveil World’s Largest Clean Energy Fund

Solar & Wind Catch Up With Coal & Gas

Solar And Wind Catch Up With Coal and Natural Gas Across The Globe

In some regions of the U.S., the cost of utility-scale solar electricity rates are *cheaper than the cost of the fuel alone* for natural-gas plants.

As solar panel prices have decreased by more than 80 percent in the past decade and wind turbines have also seen dramatic price falls, both types of renewable energy have become much more competitive.

Meanwhile, fossil fuels received $583 billion in 2014 globally in subsidies — even as renewable energy continues to receive a much lower level of subsidies ($124 billion in 2014).

Scotland Powers 960,000 Homes via Wind Power


According to a report from the Scottish Government
wind farms generated record amounts of power in the first quarter of 2015.

The same report confirms record levels of renewable energy generation were achieved in the country throughout 2014, with almost half of all electricity demand met via renewable energy generators.

Wind Power
in Scotland

Wind power is Scotland’s fastest growing renewable energy technology, with 5328 MW of installed capacity as of March 2015. This includes 5131 MW of onshore wind and 197 MW of offshore wind.

There is further potential for expansion, especially offshore given the high average wind speeds, and a number of large offshore wind farms are planned.

The Scottish Government has a target of generating 50% of Scotland’s electricity from renewable energy by 2015, and 100% by 2020, which was raised from 50% in September 2010.

If Scotland meets it’s planned target of 100% renewable energy generation in 2020, it will join a growing list of foresighted nations that are powered by clean energy.
