A 2016 agreement to install solar panels outside Macon-Bibb County government buildings was hailed as a historic moment as officials took the lead in supporting renewable energy.

But as measurements were being taken for panels that would go in the parking lot of the Macon-Bibb County Government Center, a proposed mixed-use development down the street prompted officials to change plans.

Instead, a canopy of panels atop a parking deck at the development will provide some solar power for the government center and Macon-Bibb County Emergency Management Agency.

The six-story parking deck will tie into the future Central City Commons that will feature residential lofts, retail space and a hotel. The deck’s panels will provide another source of power for the two government buildings, including providing an extra layer of protection to the EMA building in case of severe weather.

“The panels in our parking lot will definitely reduce the footprint for both Government Center and the EMA bunker, but they won’t produce enough to fully power both,” Macon-Bibb spokesman Chris Floore said in an email. “They will supplement the power we get from Georgia Power, but will provide the triple redundancy for backup power at the EMA bunker should the power go out and the generator not work.”

But the solar panels initiative has been modified from the initial agreement with Cherry Street Capital that officials approved last summer. The plan was to install panels outside the new Bibb County Sheriff’s Office investigation annex about the same time as the government center.

The CEO of Cherry Street Energy, a development company of Cherry Street Capital, told Macon-Bibb officials in June 2016 that Georgia legislation was key to expanding solar power capabilities. Third parties are now able to place solar panels and sell the energy to municipalities and commercial property owners.

There are still plans to install solar panels near the sheriff’s annex, but there hasn’t been a time frame set for when that will happen, Floore said.

Macon-Bibb will continue looking at other possible government buildings that could be powered by solar energy, but some locations are much more feasible than others.

“I think the challenge we have now is finding the open area sunny enough to get enough light to power the size of the building,” Floore said.

China Built a 248-Acre Solar Power Plant Shaped Like a Giant Panda

China is quickly taking the lead in the global race for the next and greatest form of energy. It’s not going to come from fossil fuels, which sucks for everyone who works in the fossil fuel industry and everyone with their hands fondling the balls of the fossil fuel industry. It’s good for the future of the earth, though, and everyone in it.

Solar farms aren’t generally set up to make people smile. Instead, they’re set up to make people’s lights turn on, which makes far more sense. But China decided they’d do both in a way that is just so… China. They built a solar farm shaped like a giant panda, and god damn is it ever cute.

The plant, built by the clean power giant China Merchants New Energy Group, is 248 acres and isn’t even half done. When completed, it will be 1,500 acres and have a whole other panda.

Giant pandas, for those out of the giant panda news loop, recently just made a big move. For years, they were on the endangered species list, but as of last year, they’re officially off of it.

Pandas were (and still kind of are, despite the upgrade off the endangered species list) in the direst of straits up until just a few years ago. That’s for a few reasons, all of which are thoroughly intertwined. Here they are, in quick and dirty short form: female pandas suck at reproducing. They only have a 2-3 day window in which they can get knocked up. Since humans in general and China specifically have decided that it’s fine to tear up vast tracts of land for our corn and wheat and high rise buildings, pandas were pretty much driven out of house and home. At one point, there were somewhere between 1000 and 2000 giant pandas left in the wild, and none of them were all that successful in finding each other to make that number increase. In 2004, the IUCN estimated that there were 1,596 left. Anyway, that’s your panda update. Now back to the solar farm shaped that’s just like one.

The first phase of it was finished on June 30th. At 50-megawatts, it began putting power into northwestern China’s grid. The panda will be getting a partner in a few months. The Panda Power Plant–that’s the actual name–will produce a pretty staggering amount of energy: 3.2 billion kilowatt-hours of solar energy in 25 years, according to ILF.com and China Merchants New Energy Group.

These Transparent, Solar Power-Generating Windows Are the World’s First

By: nbcmach

Energy-Neutral

A tech startup on a mission to make modern commercial and housing estates energy neutral has outfitted the headquarters of a Dutch bank with the world’s first commercial, fully transparent solar-power-generating windows.

The windows have solar cells installed in the edges at a specific angle that allows the incoming solar light to be efficiently transformed into electricity.

“Large commercial estates consume a lot of energy,” said Ferdinand Grapperhaus, co-founder and CEO of the startup, called Physee. “If you want to make these buildings energy-neutral, you never have enough roof surface. Therefore, activating the buildings’ facades will significantly contribute to making the buildings energy-neutral.”

The windows could generate 8 to 10 watts of power, according to Grapperhaus.

“This enables the user to charge a phone per every square meter [11 square feet] two times a day,” he told Live Science.

The first installation of Physee’s PowerWindows was unveiled in June in Eindhoven, in the south of the Netherlands. The headquarters of Rabobank, the Netherlands’ biggest bank, has been fitted with 323 square feet (30 square m) of the PowerWindows. The bank’s employees will be able to plug their smartphones into the windows using USB ports to charge their batteries, according to Physee.

Other buildings in the Netherlands are already lined up to receive the innovative solar technology, which has won Physee a place on the World Economic Forum’s Technology Pioneers 2017 list.

PowerWindows

At the end of June, the headquarters of the Amsterdam-based charity the Postcode Lottery were fitted with the PowerWindows. After that, Physee will move forward with its first large-scale project: a 19,000-square-foot (1,800 square m) installation in a large, newly built residential complex in Amsterdam, the Bold tower.

“I believe that every new type of glass needs power,” Grapperhaus said. “Either for the glass to be tinted electrically or heated or inside windows there are these solar blinds, which are electrical and can go up and down but also more and more you can see video glass.”

Grapperhaus said that the cost of the wiring that brings power from the grid to such windows is considerable in large commercial estates, and investing in power-generating windows would, therefore, make commercial sense.

Physee is already working on the next-generation technology that would triple the efficiency of the PowerWindows. The surface of the second generation of PowerWindows will be coated with a special material that transforms incoming visible light into near-infrared light, which is then transported toward the solar cells in the edges of the windows.

“It works similarly to a [glow-in-the-dark star],” Grapperhaus said. “The difference is that the glow star emits the green wavelength, but the coating on our windows emits light in near-infrared wavelength.”

The coating is based on the rare-earth metal thulium. Grapperhaus, together with his friend Willem Kesteloo, discovered the ability of thulium to transform a broad spectrum of light into near-infrared light in 2014, during their studies at the Delft University of Technology.

“Over time, our efficiency will improve further due to the development of better solar cells but also because of the economies of scale,” Grapperhaus said. “Right now, we are looking for iconic projects all over the world to show that a large glass building can be made energy neutral in an aesthetic way.”

Physee was among 30 early stage technology pioneers highlighted for 2017 and selected by the World Economic Forum for their potential to change the world. The list, announced June 14, consisted of firms developing various technologies, including artificial intelligence, cybersecurity solutions, and biotechnology.

Physee’s presence on the list shows that the world is starting to take climate change seriously, Grapperhaus said.

“Ten years ago, sustainability was something that wasn’t taken very seriously — not by venture capitalists, not by many governments and neither by large corporations,” Grapperhaus said. “What I have seen over the last three years is that corporations are becoming more and more responsible, governments are becoming more and more supportive, and venture capitalists are becoming more and more interested” in sustainability.

Germany Breaks Green Energy Record by Generating 35% of Power from Renewables in First Half of 2017

Germany raised the proportion of its power produced by renewable energy to 35 percent in the first half of 2017 from 33 percent the previous year, according to the BEE renewable energy association.

Germany is aiming to phase out its nuclear power plants by 2022. Its renewable energy has been rising steadily over the last two decades thanks in part to the Renewable Energy Act (EEG) which was reformed this year to cut renewable energy costs for consumers.

Germany has been getting up to 85 percent of its electricity from renewable sources on certain sunny, windy days this year.

The BEE reported on Sunday the overall share of wind, hydro and solar power in the country’s electricity mix climbed to a record 35 percent in the first half.

The government has pledged to move to a decarbonized economy by the middle of the century and has set a target of 80 percent renewables for gross power consumption by 2050.

It aims to cut greenhouse gas emissions by 40 percent in 2020 from 1990 levels and 95 percent by 2050.

Renewables Will Be the ‘Cheapest Form of New Power Generation’ By 2020

Renewable energy sources, like solar and wind, are quickly becoming as cheap—even cheaper—than their carbon-intensive counterparts like coal.

New research from Morgan Stanley estimates that renewables will be the cheapest source of power in the world in less than three years.

“Numerous key markets recently reached an inflection point where renewables have become the cheapest form of new power generation,” the bank said in a note.

“A dynamic we see spreading to nearly every country we cover by 2020. The price of solar panels has fallen 50% in less than two years (2016-17).”

Even if President Trump succeeds in withdrawing the US from the 2015 Paris climate agreement, the country could still cut more emissions than it had previously pledged to alongside 194 other countries.

“For example, notwithstanding President Trump’s stated intention to withdraw the US from the Paris Agreement, we expect the US to exceed the Paris commitment of a 26-28% reduction in US 2005-level carbon emissions by 2025,” the bank said.

What’s behind the sudden drop in renewable costs?

Wind turbine blade lengths have increased dramatically in recent years thanks to stronger materials and design. Even a small lengthening of the windmill blades can increase output exponentially, as the “swept area” is a function of the square of the turbine’s radius. Remember that high school geometry?

On the solar front, Morgan Stanley says there has been oversupply of solar panels, which is pushing production prices down. Solar installation grew 50% last year, but capacity is still 28% above installations.

The bank sees two possible benefits (beyond helping the environment) for utility companies that invest in low-cost renewables:

“First, the ability to lower customer bills from utilizing low-cost renewables can improve utilities’ regulatory environment and provide related investment opportunities in grid modernization initiatives,” writes the bank.

“Second, for utilities with large, competitive renewable development businesses, investment in renewable energy projects can generate attractive risk-adjusted returns.”
