Wind Generates 100% of Scotland's Electricity Needs for Entire Day
Wind energy had a banner day in Scotland. Thanks to an unseasonably windy Sunday, wind turbines generated more electricity than the country actually needed.

After analyzing data from WeatherEnergy, the environmental group WWF Scotland announced that wind turbines generated more than 100 percent of the total amount of electricity used in the country on Aug. 7.
As per the Guardian:
Turbines in 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—meaning wind power generated 106% of Scotland's electricity needs.
"Electricity demand during weekends is usually lower than the rest of the week," Karen Robinson of WeatherEnergy said. "Nevertheless, the fact that wind power was able to generate the equivalent of all Scotland's electricity needs shows just how far
renewables have come."
"While it's not impossible that this has happened in the past, it's certainly the first time since we began monitoring the data in 2015 that we've had all the relevant information to be able to confirm it," WWF Scotland's director Lang Banks said. "However, on the path to a fully renewable future, this certainly marks a significant milestone."
Incidentally, Aug. 7 was possibly the " windiest summer's day on record," prompting the Met Office to issue yellow "be aware" warnings. Wind speeds clocked in at 115 miles per hour at the Cairngorm mountains and roughly 60-miles-per-hour gusts in northern towns, disrupting train and ferry services and causing power outages.
Despite the weather mishaps, Banks said that the particularly windy day had a silver lining.
"While Sunday's weather caused disruption for many people, it also proved to be a good day for wind power output, with wind turbines alone providing the equivalent of all Scotland's total electricity needs," he said. "This major moment was made possible thanks, in part, to many years of political support, which means that across the year now, renewables contribute well over half of our electricity needs.
"However, if we want this ensure we reap the many benefits of becoming a low-carbon economy we need to see this political support for renewables continue."
Wind power is not the only renewable power source Scotland has at its disposal, Banks pointed out. "If we continue to take steps to reduce our energy demand, invest in storage, and increase our use of renewables we can hopefully look forward to many days that are fully powered by nature," he said.
Environmentalists believe the goal is within reach since Scotland's impressive energy mix already achieved a number of milestones, including:
• For homes fitted with
solar PV panels, there was enough sunshine to generate an estimated 100% of the electricity needs of an average household in Aberdeen, Dundee, Edinburgh, Glasgow and Inverness.
• For those homes fitted with solar hot water panels, there was enough sunshine to generate 100% of an average household's hot water needs in Aberdeen and Dundee, 98% in Inverness, 97% in Edinburgh and 94% in Glasgow.
• Wind turbines in Scotland provided 692,896MWh of electricity to the National Grid, enough to supply, on average, the electrical needs of 76% of Scottish households (1.8 million homes).
• Wind turbines generated enough electricity to supply 100% or more of Scottish homes on ten out of the 31 days of May.
• Scotland's total electricity consumption (i.e. including homes, business and industry) for May was 1,938,785MWh. Wind power therefore generated the equivalent of 36% of Scotland's entire electricity needs for the month.
According to Banks, "These figures underline the fantastic progress Scotland has made on harnessing renewables, especially to generate electricity."
"However," he added, "with less than 13 percent of our total energy needs coming from renewable sources, it's now time to widen our attention on de-carbonizing our economy beyond just our power sector."
The Scottish government states on its website that it has a renewable energy target of generating the equivalent of 100 percent of gross annual electricity consumption and 11 percent of heat consumption by 2020. But a statement from a spokeswoman suggests that government may be considering a new renewables target after the record-breaking weekend.
"Scotland's abundant energy resources play a vital role in delivering security of electricity supply across the UK," a Scottish government spokeswoman told the Guardian . "The Scottish Government is committed to supporting onshore wind, which is one of our most cost-effective low-carbon energy technologies.
"We remain fully supportive of low-carbon technologies, which offer a huge economic opportunity for Scotland and have a key role to play in our fight against the threat posed by climate change to our society and natural environment.
"We have a clear policy for an energy mix to provide energy security for the future and will set out our ambitions for an integrated approach to low-carbon technologies within our draft energy strategy later this year. This will include exploring the option of setting a new renewable energy target."
At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>

Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>

Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
Scientists have newly photographed three species of shark that can glow in the dark, according to a study published in Frontiers in Marine Science last month.
