Wind Turbines Supplied 99% of Scotland Electricity Demand Last Month

Lorraine Chow

Another month, another renewable energy record for Scotland.

Scottish wind turbines, propelled by Hurricane Ophelia’s strong winds, sent more than 1.7 million megawatt hours of electricity to the National Grid in October, according to WWF Scotland, citing data collected from WeatherEnergy.

Scotland’s total electricity consumption for homes, business and industry was around 1.75 million megawatt hours in October, meaning wind turbines alone generated 99 percent of the country’s electricity needs.

If we were just to look at households, wind power generated enough electricity for 4.5 million homes last month—that’s almost twice the number of actual households in Scotland.

“No one will be surprised that October proved to be a spectacular month for wind energy, with some high winds, including the tail end of Hurricane Ophelia,” WWF Scotland’s acting head of policy Gina Hanrahan told the Press Association.

“Fortunately our infrastructure coped well with the windy weather which provided enough to power nearly twice the number of households in Scotland and almost all of our electricity demand.”

Just this past Oct. 2, wind generated enough electricity to power 7.116 million homes, or about three times the number of Scottish households.

“We’re blown away by these figures but they are part of a pattern of increasingly green power production made possible thanks to many years of political support in Scotland. Across the year, renewables now contribute over half of our electricity needs,” WWF Scotland’s Director Sam Gardner said at the time.

But as Huffington Post UK pointed out, while these figures are impressive, the problem with so much wind energy is that all of it needs to be distributed so it does not go to waste. To solve this problem, perhaps Scotland can take a page from Germany, whose grid operators sometimes have to pay customers to take electricity off the grid because its renewable energy mix is generating so much power.

Another method would be ramping up the nascent grid-scale storage industry. The Scottish government is already trying this with its Hywind Scotland—the world’s first floating wind farm, which officially switched on last month. The farm is integrated with Statoil’s Batwind, a lithium battery that can store one megawatt-hour of power to help mitigate intermittency and optimize output.

While one megawatt-hour is not a lot—about the capacity of over 2 million iPhones—”it is the first step in a larger-scale rollout of battery solutions for renewable energy,” HuffPo UK noted.

As Karen Robinson of WeatherEnergy said, “October was an extraordinary month and provides more evidence that greater investment in both renewables and storage is the way forward.”

Renewable sources now almost one-fifth of US generating capacity

Washington DC (SPX)

May 04, 2017

According to the latest issue of the Federal Energy Regulatory Commission’s (FERC) monthly “Energy Infrastructure Update” (with data through March 31, 2017), wind and solar provided 50.84% of the new electrical generating capacity added to the U.S. grid during the first quarter of 2017.

Thirteen “units” of wind totaling 1,479 MW combined with 62 units of solar (939 MW) exceeded the 2,235 MW provided by 21 units of natural gas and 102 MW provided by one unit of nuclear power. There was also 1-MW of capacity from “other” sources (e.g., fuel cells). In the first three months of the year, no new generating capacity was provided by coal, oil, hydropower, biomass, or geothermal.

Moreover, the pace of growth of new solar and wind capacity is accelerating. For the first quarter of 2017, new capacity from those sources is 18.07% greater than that added during the same three-month period in 2016 (2,418 MW vs. 2048 MW).

Renewable sources (i.e., biomass, geothermal, hydropower, solar, and wind) now account for almost one-fifth (19.51%) of the nation’s total available installed generating capacity: hydropower (8.48%), wind (7.12%), solar (2.17%), biomass (1.41%), and geothermal (0.33%).

By comparison, at the end of 2016, renewables provided 19.17% of the total generating capacity. If current growth rates continue, renewables should top 20% before the end of this year.

Generating capacity by renewable sources is now more than double that of nuclear power (9.10%) and rapidly approaching that of coal (24.25%). **

“The Trump Administration’s efforts to reboot coal and expand oil drilling continue to be proven wrong-headed in light of the latest FERC data,” noted Ken Bossong, Executive Director of the SUN DAY Campaign. “Once more, renewables – led by wind and solar – have proven themselves to be the energy sources making America great again.”

Indian Space Agency Test-Drives Solar Electric Hybrid Vehicle

New Delhi (Sputnik)

May 04, 2017

The Indian Space Research Organisation (ISRO) added another milestone to its list of achievements by successfully showcasing a solar-electric hybrid vehicle. ISRO’s different engineering branches at the Vikram Sarabhai Space Centre in Thiruvananthapuram developed the vehicle.

The team working on the project developed a solar panel to fit on the roof of a car, along with an internal gearbox, control electronics for the battery and solar panel, and a conversion kit for fitting an electric motor to a vehicle with an internal combustion engine.

The vehicle was powered by ISRO’s famed Lithium-ion batteries, with a high power supercapacitor to meet the power demands to achieve required torque. ISRO also ensured to not compromise the safety while integrating various subsystems.

The vehicle was successfully test-driven, including an uphill drive. The space agency will now focus on building indigenous Lithium-ion fuel cells, supercapacitors and an electric motor.

“ISRO is doing a lot of things in addition to launching satellites. And all projects are interlinked and laying down the foundation for an industrial complex which will boost innovation and job creation. They have started sub-contracting many of their product building processes, which again will help in the growth of industries,” Dr. Mayank N. Vahia, Department of Astrophysics, at the Tata Institute of Fundamental Research, Mumbai, told Sputnik.

India is aiming to push the use of electric vehicles to tackle rising pollution in its cities with the government setting a target of 6 million electric and hybrid vehicles on the roads by 2020 under the National Electric Mobility Mission Plan 2020 and Faster Adoption and Manufacturing of Hybrid and Electric Vehicles.

The sales of electric vehicles in India is currently very low, rising 37.5 percent to 22,000 units in the year ended March 31, 2016, over 16,000 in 2014-15, according to the Society of Manufacturers of Electric Vehicles. Of these 22,000 vehicles, only 2,000 were cars and other four-wheelers.

The high cost of batteries, a majority of which are imported, is a major hindrance to the development of the sector. Yet another challenge is to create a network of docking stations or charging stations for electric vehicles although that is more of a demand-related problem.

“A helping hand is required to create the infrastructure… There are two concerns for electric vehicles-first is cost and second is infrastructure,” Mint quoted Abdul Majeed, partner and national auto practice leader, PricewaterhouseCoopers as saying.

The government recently asked ISRO to share its technology on Lithium-ion batteries with other public and private sector firms to give a push to the production of batteries in India and bring down the cost of electric vehicles.

Scotland Sets Wind Record, Provides Enough Electricity for 3.3 Million Homes in March

True Activist

12 April

By Amanda Froelich

Slowly but surely, it is becoming fact that households and entire countries can run on clean, renewable energy. Costa Rica, for instance, ran on renewable energy sources for 285 days in 2015 and achieved similarly in 2016. Additionally, Denmark produced 160 percent of its energy needs in one day in July of 2015 via wind power.

Now it has been reported that Scottish turbines provided 1.2 million megawatt hours of electricity to the National Grid—enough energy to meet the electrical needs of 136 percent of households in the country (or ~3.3 million homes). What’s more, 58 percent of Scotland’s entire electricity needs were met for the entire month. The Independent reported that on March 17 and March 19, enough energy was generated to power Scotland’s total power needs for an entire day.

An analysis of WeatherEnergy data by the World Wide Fund for Nature (WWF) Scotland revealed that the amount of energy generated in March increased by a staggering 81 percent compared to the same month in 2016.

WWF Scotland’s director, Lang Banks, commented on the monumental achievement:

“Given this March wasn’t as windy as it has been in some previous years, this year’s record output shows the importance of continuing to increase capacity by building new wind farms.

“As well as helping to power our homes and businesses, wind power supports thousands of jobs and continues to play an important role in Scotland’s efforts to address global climate change by avoiding millions of tonnes of carbon emissions every year,” he added.

Karen Robinson of WeatherEnergy added her insight:

“It’s massively impressive how Scotland has steadily grown its wind power output [over] the years. The total output from turbines this March was up more than four-fifths compared to the same period last year. This was enough power to provide the equivalent of the electrical needs of over three million homes. More importantly, it meant the equivalent of almost three-fifths of Scotland’s total electricity needs during March were met by onshore wind power.”

Now that Scotland has set an impressive new wind record, the WWF is calling on political parties to continue backing onshore wind power to help the country meet its carbon emission cut targets. One of the country’s goals is to deliver the equivalent of 50 percent of the energy required for Scotland’s heat, transport and electricity needs from renewable energy sources by 2030.

California Reaches Solar Milestone, Electricity Prices Turn Negative

Climate Nexus

12 April

Solar power met roughly half of California’s electricity demand for the first time on March 11, according to new estimates from the federal Energy Information Administration (EIA).

EIA estimated that almost 40 percent of electricity on the grid between 11 a.m. and 2 p.m. came from California’s large-scale solar plants, with smaller solar installations on homes and businesses supplying the rest. When factored with other sources of clean energy in the state, renewable energy accounted for more than 55 percent of power on the grid on March 11.

The abundant supply of solar in California this winter and spring has driven wholesale prices near zero or into the negative during certain hours.

“In March, during the hours of 8 a.m. to 2 p.m., system average hourly prices were frequently at or below $0 per megawatthour (MWh),” the EIA said in its report.

“In contrast, average hourly prices in March 2013–15 during this time of day ranged from $14/MWh to $45/MWh. Negative prices usually result when generators with high shut-down or restart costs must compete with other generators to avoid operating below equipment minimum ratings or shutting down completely.”

Portland Commits to 100% Renewables, Joins 25 Other Cities

Lorraine Chow

12 April

The city of Portland and Multnomah County in Oregon are joining the growing list of communities transitioning entirely to renewable energy.

Portland Mayor Ted Wheeler and Multnomah County Chair Deborah Kafoury made the announcement Monday at the June Key Delta Community Center in North Portland—the site of a former gas station-turned green building.

Portland is likely the largest city in the U.S. to take this ambitious step, the Sierra Club told the Portland Business Journal. The two areas join 25 other communities that have made similar announcements.

According to Oregon Live, the plan involves meeting all electricity needs from renewable sources by 2035. To up the ante, fossil fuels for heating and transportation will also be phased out by 2050.

Wheeler acknowledged that this commitment would not be easy.

“They will be difficult to achieve,” the newly elected mayor said.

“We’re actually going to have to make deliberate steps, and deliberate investments, and deliberate policy changes in order for this to become a reality,” Wheeler said, adding “and I’m committed to that.”

Oregon Live noted that “the city and county can lead the way in some respects, but much of the heavy lifting will depend on utilities and the market for electric vehicles accelerating.” For instance, utilities like Portland General Electric will have to quickly phase out coal and other fossil fuels.

As EcoWatch mentioned previously, committing to 100 percent renewables is not as far-fetched as it seems. The Solutions Project, which is aiming to make clean energy accessible and affordable for all, is advocating for towns, cities, states and even the whole country to convert its energy infrastructure to renewables.

The Solutions Project team published a study and roadmap illustrating how each U.S. state can replace fossil fuels by tapping into the renewable resources they have available, such as wind, solar, geothermal, hydroelectric, as well as small amounts of tidal and wave power.

The authors found that converting the nation’s energy infrastructure into renewables is ideal because it helps fight climate change, saves lives by eliminating air pollution, creates jobs in the rapidly booming renewable energy sector and also stabilizes energy prices.

Zero-emission boat prepares for round-the-world odyssey

January 11, 2017

PARIS (AP) — The first self-sufficient boat powered only by emission-free energy will start a six-year trip around the world in the spring. Energy Observer, a former multi-hull race boat converted into a green vessel equipped with solar panels, wind turbines and a hydrogen fuel cell system, will be powered by wind, the sun and self-generated hydrogen.

The 5 million euro ($5.25 million) boat, which is currently in a shipyard in Saint-Malo, will set sail from the Brittany port and will make its first of 101 stops across 50 countries in Paris as part of a six-year circumnavigation.

“This boat will demonstrate that there are many solutions for energetic transition,” said French environmentalist Nicolas Hulot, who attended the project presentation on Wednesday at the UNESCO headquarters. “All solutions are within nature.”

Designed in 1983 under the supervision of Mike Birch, the boat enjoyed a successful career in open-sea sailing races, including winning the Jules Verne Trophy in 1994, with Peter Blake at the helm. The Energy Observer project was conceived in 2015 by skippers Frederic Dahirel and Victorien Erussard, with scuba diver and filmmaker Jerome Delafosse also behind the project.

“I’m passionate about new technologies,” Erussard said. “Building a self-sufficient boat could have seemed utopian, but this is going to be an incredible vessel. It’s very promising for the future.” The technology fitted to the 30.5-meter (100-foot) boat, which is also equipped with a kite sail, will enable the production of hydrogen through electrolysis process.

“We bank on the diversity of renewable energies,” Essuard said. “And if there is no sun or wind, or at night, we have the option to draw in our hydrogen reservoirs. We will produce this hydrogen in a decarbonized manner through electrolysis of the sea water.”

According to Florence Lambert, the director of the CEA Liten research institute which devised the boat’s energy system, Energy Observer is a good example of what energy networks will look like in the near future, with its well balanced mix of renewable energies and hydrogen storage system.

“We are not talking about the delirium of an explorer or a scientific,” she said, adding that the prospects for hydrogen-powered transport look bright. Mark Z. Jacobson, an engineering professor at Stanford University who develops roadmaps for countries to convert to 100 percent renewable energies by 2050, proposes that transportation worldwide be transformed into a combination of battery-electric transport and hydrogen fuel cell-battery electric hybrid transport.

“I believe that it is fantastic that a boat powered by hydrogen and electricity will travel the world,” he said in written comments to The Associated Press. “It is an important step forward and consistent with this proposed path to 100 percent clean, renewable energy worldwide for all purposes to solve energy security, job creation, air pollution, and climate problems.”
