Winds of Change in Power Generation

Infographic: Offshore Wind Farms Continue Growth | Statista

Wars fought over oil and wars funded by oil sales are both problems we’ve seen in the 21st century. Fighting over a depleting planet-destroying energy source may soon be a thing of the past as we increase the use of renewable energy the world over. Expect the use of wind power to continue to grow in the coming years, already the rate of installation of these efficient systems has increased. Some countries that didn’t embrace wind before due to a lack of land are now building offshore installations which allow for bigger, better turbines.

Help bring peace to the world by cutting back gas use while increasing renewable energy sources.

The potential to deploy both onshore and offshore wind capacity depends on a country’s geography.

Among the leading offshore wind locations, Britain has plentiful coastlines, Germany can take advantage of its location between the North Sea and the Baltic Sea, and China uses its expansive coastal regions to good effect.

But when offshore and onshore wind capacity are combined, a different picture emerges.

Global onshore and offshore wind generation totalled 732 gigawatts by the end of 2020, according to the International Renewable Energy Agency.

Unlike Other Power Sources, Wind Turbines Still Useful When They Stop Working

- Adam Clare

Wind turbines produce renewable energy from air with a small footprint on the ground. This means they can get placed in various locations and offshore they can be massive (and therefore more efficient), but when the wind turbines reach the end of service their blades take up a lot space in landfills. Thankfully the blades can be reused to build bridges!

Even when they are no longer useful to produce electricity wind turbines live on in useful ways – another reason to build more turbines.

Originally a metals recycling company, Anmet started exploring ways to repurpose wind blades about seven years ago. Since then, it developed a small commercial business making outdoor furniture out of discarded wind turbine blades. Bridges, Sobczyk says, are the next area it would like to expand into commercially.

The company’s first blade bridge took about three years to test, permit, and build. After harvesting decommissioned blades from a wind farm in Germany, the blades were subjected to a battery of engineering tests in partnership with Poland’s Rzeszów University of Technology before being cut up to create the primary support structures for a pedestrian footbridge. In October, Amnet installed that bridge over a river in Szprotawa, the small town where the company is headquartered.

Tasmania is the First Part of Australia Powered 100% by Renewables

When it comes to energy in Australia your first thoughts are likely to be about coal and exporting coal. Despite the amble sun hitting the country, Australia has been slow on adopting renewable energy. Except for the island of Tasmania.

The rather large island has completed the push for energy self reliance by completing a wind farm. Now people on the island have limitless power thanks to a mixture of renewable resources. With luck the conversation about energy in the country will change following the success of Tasmania.

“We have reached 100 per cent thanks to our commitment to realising Tasmania’s renewable energy potential through our nation-leading energy policies and making Tasmania attractive for industry investment, which in turn is creating jobs across the State, particularly in our regions,” Barnett said.

Tasmania has long had one of the greenest supplies of electricity in Australia, with the state’s significant hydroelectricity resources supplying the bulk of the state’s power. Tasmania’s history with hydroelectricity dates back to 1895, with the Duck Reach power plant in Launceston becoming the first publicly owned hydroelectric power station in the southern hemisphere.

I See a Wind Turbine and I Want it Paint it Black

- Adam Clare

Believe it or not there are people out there who don’t want renewable energy and actively campaign to keep our power grid based on world-destroying fossil fuels. These backward thinking individuals have had success in stopping some wind turbine installations by arguing that wind turbines kill birds. Sadly, wind turbines do kill birds (but come on, coal, oil, and gas power plants kill way more than just birds).

There’s now a simple way to protect birds from wind turbines: paint one bald black. An experiment run in Norway found that a simple visual clue is enough for the few birds that hit rotating blades to evade the blades.

Applying contrast painting to the rotor blades resulted in significantly reduced the annual fatality rate (>70%) for a range of birds at the Smøla wind‐power plant. We recommend to either replicate this study, preferably with more treated turbines, or to implement the measure at new sites and monitor collision fatalities to verify whether similar results are obtained elsewhere, to determine to which extent the effect is generalizable. It is of the utmost importance to gain more insights into the expected efficacy of promising mitigation measures through targeted experiments and learning by doing, to successfully mitigate impacts on birdlife and to support a sustainable development of wind energy worldwide.

Renewable Energy Keeps Growing While Oil Companies Shrink

Without a doubt all business have been negatively impacted by the pandemic with some being hit more than others. The dirty and climate-destroying fossil fuel industry has really been hit hard (unfortunately it’s the workers who have been hurt by this and not the lying executives) and the industry isn’t even benefiting from reduced gas prices at the pump. On the other hand renewable energy companies are doing fine with only a slow down and not an industry-stopping problem. Renewable energy growth is expected this year with more utilities investing in renewable instead of fossil fuel because renewable are still cheaper than carbon-intensive alternatives.

Even the decline in electricity use in recent weeks as businesses halted operations could help renewables, according to analysts at Raymond James & Associates. That’s because utilities, as revenue suffers, will try to get more electricity from wind and solar farms, which cost little to operate, and less from power plants fueled by fossil fuels.

“Renewables are on a growth trajectory today that I think isn’t going to be set back long term,” said Dan Reicher, the founding executive director of the Steyer-Taylor Center for Energy Policy and Finance at Stanford University and an assistant energy secretary in the Clinton administration. “This will be a bump in the road.”
