New ‘Solar Paint’ Turns Your Entire House into Source of Clean Energy

solar


As governments scramble to tax their citizens into a greener world, research in the free market is proving to be the ultimate catalyst in a sustainable future. As governments pass legislation to prop up the fossil fuel industry, renewables are battling back in this epic David and Goliath match. One of the latest and most unique innovations that is showing promise to free humanity from the grip of fossil fuels is solar paint. Yes, solar paint.


Researchers in Australia, from the Royal Melbourne Institute of Technology (RMIT), have developed a solar paint that can absorb water vapor and split the molecule to separate it into hydrogen — the cleanest source of energy.



The research has recently been published as “Surface Water Dependent Properties of Sulfur Rich Molybdenum Sulphides – Electrolyteless Gas Phase Water Splitting” in ACS Nano, a journal of the American Chemical Society.


According to a report on RMIT’s website:



The paint contains a newly developed compound that acts like silica gel, which is used in sachets to absorb moisture and keep food, medicines and electronics fresh and dry.


But unlike silica gel, the new material, synthetic molybdenum-sulphide, also acts as a semi-conductor and catalyses the splitting of water atoms into hydrogen and oxygen.


Lead researcher Dr Torben Daeneke, from RMIT University in Melbourne, Australia, said: “We found that mixing the compound with titanium oxide particles leads to a sunlight-absorbing paint that produces hydrogen fuel from solar energy and moist air.



“Titanium oxide is the white pigment that is already commonly used in wall pain, meaning that the simple addition of the new material can convert a brick wall into energy harvesting and fuel production real estate.

“Our new development has a big range of advantages,” Daeneke said. “There’s no need for clean or filtered water to feed the system. Any place that has water vapor in the air, even remote areas far from water, can produce fuel.”


The solar paint is so efficient that it doesn’t need humid climates to function either. This technology can work in arid climates too.


“This system can also be used in very dry but hot climates near oceans. The sea water is evaporated by the hot sunlight and the vapor can then be absorbed to produce fuel,” Daeneke explains.



Professor Kourosh Kalantar-zadeh, Daeneke’s colleague, explained on the university’s website how hydrogen is the cleanest source of energy and could be used in fuel cells. But that is only the beginning. This solar paint could also serve as a replacement for fossil fuels as it can be used in combustion engines.


“The produced hydrogen can then be directly used either in a fuel cell or in a combustion engine,” says Daeneke.




“Ultimately we hope that the solar paint might be used alongside traditional solar cells, potentially coating areas that receive too little light to be viably covered with expensive solar cell modules,” Daeneke said.


As Inverse reports, Although Daeneke thinks it will take at least 5 years to engineer the final product, he expects the paint will be very cheap. Since there are already cars and buses that are hydrogen powered today, Daeneke says, once the collection process is completed this could be a powerful source of clean energy in the future. And because it’s effectively just a white paint, you could put it on your house or fence to create another kind of clean energy with a little humidity and sunlight.

Oklahoma Claims it Owns the Wind, Caves to Oil Lobby to Tax Energy from the Air

Oklahoma — In a slavish display of fealty to the oil and gas industry, Oklahoma Governor Mary Fallin put forward a plan in the executive budget proposal to tax the state’s wind industry out of existence.


By ending tax credits — ahead of schedule — and imposing the nation’s highest tax on wind power, this Oklahoma law would make renewable wind energy cost-prohibitive while enriching the fossil fuel industry.


EcoWatch reports, “The budget proposes a .5 cent per kilowatt-hour on wind energy—five times the wind tax in Wyoming, which along with South Dakota are the only states that tax wind energy—and accelerates the end of a tax credit, currently set to expire in 2021.”


The governor’s budget mirrors another bill working its way through state legislature.


Separate legislation proposed by Rep. Earl Sears would end “accumulation of new credits for zero-emission electric generation July 1 and caps annual payments for existing credits at $15 million a year,” reports Tulsa World.


“There’s no question wind has a place in this great state, and has a place in the energy sector,” Sears noted. “What is at hand, we absolutely have to have serious discussion about credits for wind.”



Perhaps the most acceptable avenue would be to end taxpayer-funded government welfare for all profiteering industries and corporations, including for wind and Big Oil. But tax credits — given the growth of wind-generated energy — provide fertile ground for oil and gas to go to war against renewables, in general.


“I believe the wind industry has done much better than we thought they could do, maybe than even they thought they could do,” explained Rep. Weldon Watson.


Sears said he’s “sure” ending tax credits would “impact” planned wind farms, but “When I get that call from them, I’ll tell them we’re having the same issue in state government.”


Politicians aren’t alone in seeking to get wind power off the government teat.


A group of Big Oil executives — including President Trump’s advisor, Harold Hamm, of Continental Resources — comprise the Windfall Coalition, which believes Oklahoma shouldn’t subsidize wind energy when the state should be turning more toward natural gas and has pushed lawmakers to make the appropriate changes.



Windfall and both the Oklahoma Property Rights Association and WindWaste have worked for years to tightly restrict the locations of turbines and end state tax credits.


Fossil fuels have faced quite a challenge from the wind industry, as NewsOK reported last year, “Oklahoma added more than 1,400 megawatts of wind capacity in 2015. The state remained in fourth place among states for wind capacity, with 5,184 megawatts. Almost 700 megawatts are under construction in Oklahoma, the American Wind Energy Association said in its latest market report. Oklahoma now gets about 17 percent of its electricity from wind.”


But, as Hamm explained, “We believe now is the time to end wind subsidies in Oklahoma, due to the federal production tax credit that has been extended.”


“Hamm’s group said the wind industry’s state incentives — which include a five-year property tax exemption and a 10-year, zero-emissions tax credit worth 0.5 cents per kilowatt-hour of generation — are too generous and aren’t needed anymore,” NewsOK explained. “The group also said increased use of wind generation by utilities comes at the expense of them using natural gas, dampening the collection of gross production taxes.”





In other words, wind energy should be done away with because it isn’t profitable for the oil and gas industry — renewables simply pad the wrong pockets.


Proposals to, in essence, penalize the wind industry financially — taxing it beyond viability — constitute an attempt to own the wind.

Paradigm Shift — Solar & Wind Jobs Growing 12 Times Faster Than US Economy

In yet another indication that the clean energy revolution is well underway, a new report finds that solar and wind jobs are growing 12 times as fast as rest of the U.S. economy. These jobs have grown by about 20 percent annually in recent years.


The report from the Environmental Defense Fund (EDF) notes that renewable energy jobs, totaling about 769,000 by the end of 2015, experienced “a compound annual growth rate (CAGR) of nearly 6% since 2012,” while “fossil fuel extraction and support services slumped, with a -4.25% CAGR over the same period.”


Market forces are driving this phenomenon, due to dramatic reductions in manufacturing and installation costs, coupled with stagnant demand for oil and coal. Unsubsidized solar is now as cheap as coal and natural gas and even wind in emerging markets, and solar prices will continue to rapidly fall.


What’s more, these renewable energy jobs cannot be outsourced due to their on-site nature and they pay above average wages.



“Many jobs in the solar and energy efficiency space are in installation, maintenance and construction, making these jobs inherently local and contributing to the growth of local economies. Average wages for energy efficiency jobs are almost $5,000 above the national median, and wages for solar workers are above the national median of $17.04 per hour.”



Sustainability jobs – meaning those in energy efficiency and renewable energy, as well as in waste reduction, natural resources conservation and environmental education – now total 4-4.5 million in the U.S., up from 3.4 million in 2011.

Energy efficiency jobs represent about half of these jobs at 2.2 million, the majority of which are in small businesses with 10 employees or fewer. Investing in this sector is wise, as “energy efficiency investments create more jobs than those in fossil fuel industries: estimated at approximately 8 jobs (direct and indirect) per $1M invested compared to about 3 jobs in fossil fuels.”


As we reported in January, the solar industry employed more people in electricity generation than gas, coal and oil combined. Cheap solar and natural gas prices – not government policy – have been driving coal out of the market since 2006.


Trillions of dollars will be invested worldwide in clean energy over the coming decades, and utility companies in the U.S. have already focused on clean energy due to a variety of factors including the predicted continual drop in prices.



All of this means that any efforts by the Trump administration and new Congress to prop up fossil fuels and stymie clean energy would bring a severe detriment to economic and job growth. Trump has been harping on ‘bringing back coal jobs,’ but as Bloomberg News points out, “renewable energy provides five times more jobs than coal mines.”


Not to mention the fact that mountaintop removal – the preferred method of coal companies – obliterates vast swaths of forested habitat and fills streams and valleys with toxic waste. The pollution from coal mining degrades the health of nearby communities where coal miners live. The health impact of fossil fuel burning is estimated at $74.6 billion every year.

Bloomberg notes that solar and wind jobs, totaling more than 300,000 in the U.S. in 2016, are “a significant source of employment in many of the rural red states that supported Donald Trump’s campaign.”


“We’re hiring workers in the rust belt,” said Tom Kiernan, CEO of the American Wind Energy Association. “We’re helping families keep farms they’ve held for generations. The lifeblood of our industry is in rural America.”





Most indications at the moment are that Trump and his cadre of fossil fuel advocates set to run federal agencies plan to cut clean energy research and development programs. While the free market will continue pushing our energy paradigm toward renewable energy, a federal government working against the tide could mean that the U.S. misses out on the economic opportunity of the clean energy revolution.

In 2016, Solar Employed More People in Electricity Generation Than Gas, Coal, & Oil COMBINED

A new U.S. Energy and Employment Report is providing yet another indication that our energy paradigm is rapidly shifting away from fossil fuels. The most promise for jobs lies in clean energy, with solar jobs in particular rising at a tremendous rate.


The U.S. Dept. of Energy’s second annual report found that, in 2016, solar employment was almost double that of fossil fuel employment in the Electric Power Generation sector.



“Proportionally, solar employment accounts for the largest share of workers in the Electric Power Generation sector. This is largely due to the construction related to the significant buildout of new solar generation capacity. Solar technologies, both photovoltaic and concentrating, employ almost 374,000 workers, or 43 percent of the Electric Power Generation workforce. This is followed by fossil fuel generation employment, which accounts for 22 percent of total Electric Power Generation employment and supports 187,117 workers across coal, oil, and natural gas generation technologies.


Rising employment in solar, wind, and natural gas coincides with the shift in energy generation by source, especially given recent large-scale distributed and utility-scale solar capacity additions.”



The total number of jobs in the Traditional Energy and Efficiency sectors was 6.4 million for 2016, which includes: 1) electric power generation and fuels, 2) transmission, distribution and storage, 3) energy efficiency, and 4) motor vehicles.


More than 300,000 new jobs were added across the entire spectrum, making up about 14 percent of total jobs created in the country. The report notes that the “solar workforce increased by 25% in 2016, while wind employment increased by 32%.”

These revealing job numbers mirror dramatic shifts going on in the sources for electricity generation, driven by crashing solar prices and the fracking boom which led to a glut of natural gas. Cheap solar and natural gas prices – not government policy – have been driving coal out of the market since 2006.



“…net generation from coal sources declined by 53 percent between 2006 and September 2016, while electricity generation from natural gas increased by 33 percent and solar by over 5,000 percent—from 508,000 MWh to just over 28,000,000 MWH.”



The report comes on the heels of news that unsubsidized solar is now cheaper than fossil fuels in many countries for large-scale electricity generation. Solar prices will continue dropping, and within a decade or two solar energy will be half the cost of coal or natural gas.


This transition is being driven by market forces, as Bloomberg highlighted in late 2015. Their analysis shows that within 25 years, solar will be the primary electricity source as it outcompetes natural gas and coal on every level.


Speaking of subsidies, the U.S. fossil fuels receive about $37 billion a year in subsidies. The only industry that will be reliant on government to prop it up in the near future is the fossil fuel industry. The cost of fossil fuels also does not include the cost to human health from pollution, estimated at $75 billion per year, and the cost of military protection of overseas oil, which amounts to about $30 billion per year.



According to the DOE report, three sources of energy made up 93 percent of new additions to the energy grid in 2016, with solar coming first at 9.5 GW. Natural gas added 8 GW and wind energy added 6.8 GW).



“In fact, between September 2015 and September 2016 alone, distributed solar photovoltaic generation increased 35 percent nationwide, while estimated total solar—both utility-scale and distributed generation—increased by 52 percent across the country.”



While market forces are driving a remarkable shift toward clean energy in the power grid, transportation remains firmly dependent on oil. But transportation too will be experiencing a remarkable shift in coming years, as automakers such as Ford Motor Company are set to invest billions in electric vehicles. A breakthrough technology called an ‘artificial leaf’ – which turns sunlight into hydrocarbon fuel – will further revolutionize our transportation paradigm.

World markets have firmly indicated that the future is clean energy, with trillions of dollars in investments coming over the next few decades. The new jobs report tells us that solar and wind energy provide the best opportunity for job growth in the U.S.


China got the message, and just announced it will invest $361 billion over the next three years in clean energy, marking a major turn away from coal.


President Trump has repeatedly called for using his power to ‘bring back the coal industry,’ but doing so would be in complete contravention of market forces and would be a great disservice to Americans looking for jobs.


If the new administration and Congress continue with their obsession over fossil fuels – and the antipathy toward clean energy – it could mean America loses out in the massive economic opportunity that is clean energy.

After Leaking Radiation in New York For DECADES, Indian Point ‘Ticking Time Bomb’ to Finally Close

Buchanan, NY — Intensely controversial Indian Point nuclear power plant will completely cease operations by 2021, but the move to shutter operations on the facility — located just 25 miles north of New York City — has itself stirred contention.


Legal and environmental battles have raged for years over Indian Point, which supplies nearly one-third of the energy generation for the metropolis and has — in recent times, at least, officially — one of the best track records of any nuclear plant in the U.S.


New York Governor Andrew Cuomo has for years fought to shut down Indian Point — which he has called a “ticking time bomb” — both for its proximity to a sprawling urban populace and for the plant’s disputable safety record. Announcing the coming closure, Cuomo stated this week,


“For 15 years, I have been deeply concerned by the continuing safety violations at Indian Point, especially given its location in the largest and most densely populated metropolitan region in the country. I am proud to have secured this agreement with Entergy to responsibly close the facility 14 years ahead of schedule to protect the safety of all New Yorkers. This administration has been aggressively pursuing and incentivizing the development of clean, reliable energy, and the state is fully prepared to replace the power generated by the plant at a negligible cost to ratepayers.”


Wind power will be the governor’s primary focus, but that sufficient clean energy infrastructure to replace the two gigawatts of power produced at Indian Point isn’t yet in place has brought the eminent shuttering of the nuclear facility into question by both the industry and, surprisingly, even some environmental advocates.


Entergy, which operates Indian Point, will now be able to renew expired licenses to keep the plant functioning until the two remaining reactors — the original Unit 1 ceased operation in 1974 — go offline for good. Indian Point Unit 2 is slated to shut down as early as April 2020 and Unit 3, April 2021 — but Entergy plans to seek license renewals through 2024 and 2025, respectively, in case the electrical grid operator feels the system can’t handle the loss that soon.


In a press release concerning its agreement to shutter the facility, Entergy stated:



“The two operating units at the Indian Point Energy Center will close in 2020-2021 after powering New York for more than four decades with clean, safe, and reliable electricity. The early and orderly shutdown is part of a settlement under which New York State has agreed to drop legal challenges and support renewal of the operating licenses for Indian Point, located in the Village of Buchanan in northern Westchester County. The shutdown will complete Entergy’s exit from its merchant power business because of sustained low wholesale energy prices.”


Indian Point, despite claims the plant has one of the best operating records in the U.S., has had its share of mishaps and close calls — rattling the nerves of residents nearby and in the New York metroplex.


In early February 2016, a spike in radioactivity in three monitoring wells — one measuring 65,000 percent above normal — induced a small panic, as Cuomo released a statement asserting, “radioactive tritium-contaminated water leaked into groundwater.” Then, the following month, Unit 3 shut down because of excessive bird poop — seriously. In 2015, the plant stopped operations after a balloon became entangled in electrical wires. Though both shutdowns occurred precisely as designed, for area residents, in particular, they evince the tenuous nature of nuclear power.


But the spike in radioactivity in the wells and the seemingly humorous nature of those shutdowns add to, as Anti-Media reported, “a list of many issues over the years — in 1979, alone, there were 14 ‘incidents’ at Indian Point 2, and nine at Indian Point 3. But even cursory research reveals numerous leaks at the plant, including a ‘serious’ 100,000 gallon leak in 1980, an 8,000 gallon leak in 1981, and a leak of an unspecified amount in 1995. Tritium-and nickel-63-tainted water leached into the groundwater supply in 2006. In 1982, Indian Point was the target of the first hearing in history by the Nuclear Regulatory Commission (NRC) to determine whether a nuclear plant should simply be closed down due to its safety record.”


On the banks of the Hudson River in Buchanan, Indian Point Unit 1 was the first nuclear plant designated for civilian use upon construction in 1962 — but that location, itself, has stoked fears in the past few years. While not as storied as the notorious San Andreas fault in California, the long-dormant Ramapo Fault Zone — comprising the region where the plant is located — has begun to stir once again, earning the attention of geologists and scientists concerned for New York City and the proximity of Indian Point.


“A study by a group of prominent seismologists suggests that a pattern of active but subtle faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed,” Columbia University’s Earth Institute found in 2008. “Among other things, they say the controversial Indian Point nuclear power plants, 24 miles north of the city, sit astride the previously unidentified intersection of two active seismic zones.”


Then in 2011, the NRC studied and rated the nation’s nuclear plants on the potential for core damage in relation to seismic risk — Indian Point Unit 3 landed conspicuously at the top, its risk having risen 72 percent over previous evaluations.



“The chance of an earthquake causing core damage at Indian Point 3 is estimated at 1 in 10,000 each year,” investigative reporter Bill Dedman explained. “Under NRC guidelines, that’s right on the verge of requiring ‘immediate concern requiring adequate protection’ of the public … The odds take into consideration two main factors: the chance for serious quake, and the strength of design of the plant.”


Victor Gilinsky — an energy consultant and former member of the NRC — penned an op-ed for the New York Times in December 2011, with the telling title, “Indian Point: The Next Fukushima?” which stated,


“A severe accident at Indian Point, whose two reactors [that remain in operation] opened in 1974 and 1976, is a remote but real possibility. We’ve had two severe accidents with large releases of radioactivity in the past. The Chernobyl accident was dismissed by Western countries on the grounds that it was the product of Soviet sloppiness and ‘couldn’t happen here.’ But the Fukushima accident involved reactors built to American designs.

“The essential characteristic of this technology is that the reactor’s uranium fuel — about 100 tons in a typical plant — melts quickly without cooling water. The containment structures surrounding the reactors — even the formidable-looking domes at Indian Point — were not designed to hold melted fuel because safety regulators 40 years ago considered a meltdown impossible.


“They were wrong, and now we know that radioactive material in the melted fuel can escape and contaminate a very large area for decades or more. It doesn’t make sense to allow such a threat to persist a half-hour’s drive from our nation’s largest city.”


Now, fortunately for millions in what would be the fallout zone if catastrophe struck, Indian Point nuclear plant has a shut down date in sight.


However, closing a nuclear facility is anything but instantaneous — decommissioning can take years, and involves the delicate task of dismantling reactors’ cores, removing spent fuel, storage, and then transport to a designated safe containment cask. Material from the unit shuttered in 1974 remains on the premises to this day.


Entergy stated it would assist the nearly 1,000 full-time Indian Point workers in finding gainful employment. Around 190 will stay after the final shutdown to assist in the decommissioning process.
