Obama backs community solar power as rooftop energy alternative

White House pushes community solar power as rooftop
, USA TODAY, 19 Nov 15  WASHINGTON — About half of electric customers can’t text-community-energyinstall solar panels because they don’t own their building, don’t get enough sun or don’t have a large, south-facing roof to install solar panels, according to the U.S. Department of Energy.Those technical challenges are a particular hurdle for low- and middle-income customers — and that’s why the Obama administration is pushing a solution known as community solar.

The White House hosted a summit Tuesday to bring together major solar players to figure out ways to expand retail solar power from traditional rooftop arrays to a model in which households and businesses invest in shared solar systems. The administration announced that 68 cities, states, and businesses had signed on to a White House initiative to promote community solar, with an emphasis on low- and moderate-income households.

Obama solar

Those commitments are expected to bring solar power to to more than 20,000 households in 21 states, the White House said. And, just as importantly for President Obama, it will allow the United States to expand its use of clean energy as Obama prepares to travel to Paris for an international climate summit where he’ll press other companies to make similar strides to reduce carbon pollution from fossil fuels…….

Another participant, Michelle Moore of the nonprofit Groundswell, works as a community organizer to try to create markets for community solar power in places where it doesn’t yet exist. She said the White House summit was helpful in bringing for-profit utilities, cooperatives, local governments, non-profits and financiers together to make connections.

“Our role is organizing customers so that they’re able to have more of a say in what kind of energy they want and how they want to buy it,” said Moore, a former environment policymaker at Obama’s White House Council on Environmental Quality. “It’s a way to buy into a solar project without a home construction project.”

Mayor of London calls on UK govt for tax help for local community solar power

community-solarflag-UKBoris Johnson: Treasury is endangering community renewables, Guardian, , 12 Nov 15
Mayor of London calls on the government to reconsider plans to remove tax relief for investors in community energy projects 
Boris Johnson has warned the Treasury it is endangering efforts by local communities around the UK to build their own renewable energy projects.

In a letter to the financial secretary to the Treasury, David Gauke, the mayor of London and Tory MP called on the government to reconsider its proposals to remove various forms of tax relief for investors in community energy.

More than 100 green energy groups have already said the change will “decimate” the sector, which has installed community-owned solar panels on village halls, small hydro schemes on rivers and wind turbines on farms.

Johnson is concerned that “the proposals may endanger the expansion of the sector given the investment required for the upfront capital costs” and “there is a danger of unintended consequences”, wrote the deputy mayor for environment and energy, Matthew Pencharz.

The mayor also thought that while such schemes might be small individually, in aggregate they are important to the security of London’s future energy supply, and a key part of efforts to cut the capital’s carbon emissions.

The short-term nature of the tax changes – which are due to come into effect at the end of November – could also put an end to schemes that are already in development or fundraising, he said.

One high-profile scheme for a community-owned solar array in a West Sussex village that was at the centre of anti-fracking protests, has already been shelvedas a result of the Treasury’s plans, announced in the finance bill last monthA recent report found more than £100m worth of community energy projects were at risk from the changes…….

Small scale solar power opens up big future for millions in Tanzania

“People who have small shops no longer close their shops early because they don’t have electricity. They can now operate until late at night. The availability of solar electricity has helped control immigration of people to urban areas,” says alternative energy specialist Dr Brenda Kazimili at the University of Dar es Salaam.

The government now wants all health centres and dispensaries that are not connected to the grid countrywide to be provided with solar panels.

How Tanzania plans to light up a million homes with solar power, Guardian, , 29 Oct 15, In a country where only 40% of people have access to grid electricity, the government is looking to sunshine to power health centres and homes efore solar panels were installed at Masaki village’s only health centre, doctors, nurses and midwives had to use dim flashlights or the glow from their cellphones to deliver babies and treat night-time emergencies.

In one case in 2010, a man arrived late after a motorcycle accident and needed a wound stitching. As the nurse began the procedure by the light of her torch, she felt a cold slithering sensation against her legs.

A large black snake was moving across the dark, cement floor. The nurse fled, leaving the patient in the dark with the snake.

The work of the centre, which is five hours drive down a dirt track from the capital Dar es Salaam and serves a population of 1.5 million people in surrounding villages, is now transformed by a two kilowatt solar array installed on the roof at a cost of $15,000 (£9,700). And the government wants many more like it.

In February, it launched its One Million Solar Homes initiative to provide the sun’s power to 1m properties by 2017. Off Grid Electric, the Tanzanian company implementing the initiative, says it will provide power to 10% of the country’s homes. Currently, only 40% have access to grid power with access particularly sparse in rural areas.

The challenge across Africa is daunting. ……

Funding for the million homes initiative has come partly from the government’s Rural Energy Agency – which spends $400m a year – and international donors such as the World Bank. And in rural areas, microfinance organisations are now lending to allow householders to by solar panels. The total installation can cost up to $1,000.

“People who have small shops no longer close their shops early because they don’t have electricity. They can now operate until late at night. The availability of solar electricity has helped control immigration of people to urban areas,” says alternative energy specialist Dr Brenda Kazimili at the University of Dar es Salaam.

The government now wants all health centres and dispensaries that are not connected to the grid countrywide to be provided with solar panels.

Back at Masaki village health centre, the changes were much needed. “We’d begged for so long for solar power at this health centre. Life was unbearable here. We faced so many challenges and it was hard to work at night or do tests that required electricity,” said clinical officer Ahmed Mkamba.

“[Now] we have even installed a satellite dish to keep the health workers entertained after work. Mothers no longer have to be sent to far-away health centres to conduct simple tests and health workers don’t have to walk long distances simply to charge mobile phones.”

Health workers use the power from the solar panels (and the battery installed so that they can use the power at night) to run a computer which keeps patient records, to light the centre’s compound which covers about three or four acres of land and to operate HIV/Aids testing equipment. This means that patients no longer need to be sent to the district hospital 28km away.

And says Mkamba: “The lights keep away the snakes.”

New batteries coming for solar powered homes

solar-rooftopsWant a Solar-Powered Home? Here’s a New Battery That Won’t Ignite
As solar panels and wind turbines spread worldwide, they’ll need batteries to store power for times when they don’t produce it. Harvard debuts a promising prototype. 
By Wendy Koch, National Geographic  SEPTEMBER 24, 2015 If you dream of an off-grid house powered by the sun, plan on a battery to store energy for cloudy days—ideally, one that won’t catch fire. Harvard researchers might have just the fix.

 In the race to build the battery of the future, they’re unveiling a unique option. They say their flow battery is the first made with cheap, non-toxic, non-corrosive, non-flammable, high-performance materials.

“It is a huge step forward. It opens this up for anyone to use,” says Michael Aziz,  Harvard University engineering professor and co-author of a study published Thursday in the journal Science. Because the battery is safe and non-corrosive, he says, it’s well suited for both businesses and homes, adding: “This is chemistry I’d be happy to put in my basement.”………

New measures to promote rooftop solar, by President Obama

US President Barack Obama unveils measures to encourage solar power use,SMH, August 25, 2015 GARDINER HARRIS. The Obama administration has announced a slew of small measures designed to encourage the use of solar power in the US hours.

The measures included making an additional $US1 billion ($1.4 billion) in loan guarantee authority available in an existing federal program for the kind of residential rooftop solar projects that have become popular in places like California.

But none of the announced measures would provide the impact on the solar industry of the Clean Power Plan, which was announced this month and requires states to cut carbon emissions by an average of 32 per cent. That plan provides strong incentives for much of those reductions to come from the development of renewable energy resources – exactly what executives at the conference in Nevada are looking to sell.

“We’re going to make it even easier for individual homeowners to put solar panels on their roof with no upfront cost,” President Barack Obama told the summit. “A lot of Americans are going solar and becoming more energy-efficient not because of tree huggers — although trees are important, just want you to know — but because they’re cost-cutters.

With the nation’s new electrical needs growing only modestly, renewable power executives are depending on electric utilities finally retiring their aging coal-fired power plants and replacing them with renewable power sources. That process is happening anyway, but the administration’s power plan is expected to accelerate it……..

Control of electricity at the local level, with batteries for renewable energy

In the end, the solution might lie on a smaller scale: giving everyone the power to store their own power. Tesla is one company of several in this game: it recently announced a device called the Powerwall, designed for homes and businesses. It uses the same batteries as electric cars to store energy, either from renewables or cheap night-time electricity, ready to be used during the day.

If such systems become commonplace, we might all become a little more aware of where our energy is coming from, and how our own behaviour affects its use and production

batteries Terence Eduarte

The battery revolution that will let us all be power brokers, New Scientist 22 July 15 
Companies are racing to find better ways to store electricity – and so provide us with cheaper energy when and where we want it “……..
. Although they are still dwarfed in most respects by the bulky lead-acid batteries found in almost every car on the road today, in 2015, lithium-ion batteries will account for around a third of the money spent on rechargeable batteries globally (see “Turn it on”), and just under a sixth of the total energy stored, according to French research firm Avicenne.

At the same time, their performance has improved immensely: design tweaks have tripled the energy stored in a given volume since the technology was commercialised in 1991. Success has bred success, and lithium-ion batteries have found new and bigger applications, such as electric vehicles (see “Powered by Lithium”). For example, the Model S electric car designed by Tesla Motors, a company owned by serial entrepreneur Elon Musk, is powered by thousands of small lithium-ion batteries arrayed between the car’s axles. It can go from zero to 95 kilometres an hour in 3.1 seconds, and can travel about 430 kilometres on a single charge, although charging it can take many hours.
Tesla has no plans to stop there. Lithium-ion batteries are so important to the company that it has taken manufacturing into its own hands, building a “Gigafactory” just outside Reno, Nevada. By 2020, the company plans to produce as many lithium-ion batteries annually as the entire world produced in 2013 – enough for a fleet of 500,000 electric cars – and with a 30 per cent reduction in production cost per battery………

Small scale energy revolution in India’s slums – from Australia solar company

Australian solar company Pollinate Energy brings light to slums of India ABC Foreign Correspondent  By South Asia correspondent Stephanie March 26 May 15 With indoor air pollution from kerosene lamps and stoves the second largest cause of death in India, one company, founded by Australians, has come up with a solution to the problem.

Every night in the sprawling shanty towns of the country of 1.2 billion people, the air fills with dense, black smoke.

“We used to get oil from the market and pour it into the lamp and light it; the house used to get full of soot and dirt,” said Abdul, a slum-dweller in Bangalore who lives in a hut made of wooden board and tarpaulin.

That was until Abdul bought a portable solar light from a company called Pollinate Energy, founded by five young Australians.

“After we got this solar lamp a lot of things improved,” Abdul said. “Now we don’t worry that there will be a fire.”

There are 400 million people in India who do not have access to electricity. Many of them live in the thousands of slums found in the country’s cities.

“They’re people who’ve come from rural places to the city to find work, usually in construction sites or as rag pickers, and to make a life for themselves,” Pollinate Energy co-founder Kat Kimmorley said.

“They are sort of like the modern day pharaoh slaves building this next new empire that we all … take for granted that is just coming up before our eyes and yet [is] completely ignored and sort of invisible to the state here.”

Pollinate Energy employs locals to go tent to tent to sell the solar lights.

The lights cost about $30 each — a lot of money for people who earn a few dollars a day. The company allows customers to pay in instalments.

“For most of the people we work with in these urban slums, when we provide a solar light, every time I sell it I think this is the same type of investment as for a plasma screen TV in Australia,” Ms Kimmorley said.

More mobile phones than toilets in India

The lights are popular — the company has sold more than 7,000, and is expanding to two more Indian cities. And that is partly because they double as a phone charger.

“We discovered that the customers would pay double what they would pay for a solar light for a solar-powered phone charger,” Ms Kimmorley said.

“So it is just testament to the fact that it is not just what we think would improve peoples’ lives but also what keeping up with the Joneses means in an urban slum. It’s having a mobile phone and being able to charge that mobile phone,” she said.

The uptake of mobile phones in India has been huge — there are more mobile phones than there are toilets.

The team at Pollinate believes solar lights can follow the same path………

Portable solar desalination – ideal for developing countries

Scientists are turning salt water into drinking water using solar power The world needs this. Science Alert BEC CREW 27 APR 2015 By inexpensively turning salt water into drinking water using sustainable solar power, a team from MIT in the US has not only come up with a portable desalination system for use anywhere in the world that needs it, but it’s just won the 2015 Desal Prize – a competition run by USAID to encourage better solutions to water shortages in developing countries.


In order to win the $140,000 prize, entries had to demonstrate how their invention not only works well, but is cost-effective, environmentally sustainable, and energy efficient. And the MIT researchers teamed up with US-based manufacturing company, Jain Irrigation Systems, to do just that.

The team’s invention works by using solar panels to charge a cache of batteries that power an electrodialysis machine that removes salt from the water and makes it perfectly drinkable. David L. Chandler explains for MIT News:………

They’re now hoping to expand their field tests to rural communities in developing countries, in the hopes that they can set them up as irrigation systems in small farms. “A solution with the potential to double recoverable water in an environment where water is becoming more precious by the day could have a huge impact,” environmental and civil engineer Susan Amrose from the University of California at Berkeley, who was not involved in the research, told MIT News. Sources: MIT NewsPopular Science

An exciting solar energy idea – still at the dream stage?

THIS STUNNING HIGH-RISE HYDROPONIC FARM GENERATES RENEWABLE ENERGY AND REPRESENTS NEW HOPE FOR BIG CITIES ACROSS THE GLOBE  [ good pics] by Rachel Oakley in Exhale on Friday 8 May 2015 To make Earth a greener place, Aprilli Design Studio got its designers together to create an incredible ecological system known as the Urban Skyfarm, for a site right in the heart of downtown Seoul.

This is not your average eco-friendly building. It’s so much more.

The Urban Skyfarm isn’t office space or apartments, but rather a complete ‘living machine’ that filters water and air, provides vegetables and herbs for the community, and produces renewable energy at the same time.

There are four major components to the Urban Skyfarm: the root, trunk, branch, and leaves.

The root section provides space for a market or public activities. The trunk can be used as a community garden space for residents. The trunk is also divided into eight individual branches (the leaf portions), which each support farming decks which are suspended from each branch by trusses and tension cables. These farming decks are spread out to receive maximum sunlight throughout the day.

Now, if that wasn’t enough, listen to this: the high rise farming system plans to operate on renewable solar and wind energy alone. Meaning, it operates completely on its own energy, and indeed provides energy to the grid…….

Despite the USA’s nuclear lobby – solar power is winning in Japan

flag-japanI predict, because solar is rising so rapidly in the land of the rising sun, that Japan will never restart any of its nukes – even though the U.S. media is demanding Japan restart one of its nukes. Let us pray that the solar home owners in Japan win this race against nuclear power. Our lives too depend on solar winning

sun-championFour years after Fukushima, Japan is solar-powered Bay View by Theresa Coleman and Paul Kangas, 29 Apr 15 In the week before the March 11, 2011, earthquake at Fukushima, one person, Prime Minister Naoto Kan, did an extraordinary act that set Japan’s energy course in history for the next 100 years. He was able to convince the Japanese Parliament to pass a solar payment policy (SPP), that required big utilities in Japan to pay solar home owners $0.53 kwh for 20 years.

This is amazing. One, because the rate is very attractive to solar home owners and two, because he even made the effort.This one policy shift is now making Japan one of the leading solar powered nations on earth – far ahead of California or the U.S.

Number one in solar generation in 2014 was Germany. The same year they won the World Cup in soccer. They are on a roll.It is going to be interesting to see if China becomes No. 2 in 2015. It is a tight three-way race between Japan, Germany and China. Who will win?

The really big question is: “What inspired Prime Minister Naoto Kan to introduce this solar payment policy to the Japanese Parliament the day before Fukushima? Was it Chernobyl?

Apparently Kan had read the book “Solar Economy” by Hermann Scheer the year before. It got him to thinking about how solar policy could actually be drafted to shut down all the nuclear power plants in Japan over the next 50 years……….

This one policy shift is now making Japan one of the leading solar powered nations on earth – far ahead of California or the U.S. Number one in solar generation in 2014 was Germany.

UK plan for solar panels on every school roof

solar-jobCrowdsourcing funds will put solar panels on every school roof   Labour says schools would benefit by average of £8,000 a year and spread understanding of sustainability Every school in the country will be offered help with installing solar panels on their roofs under plans being considered by Labour. Schools would not only be able to reduce their bills, but could also raise revenues by selling surplus electricity back into the national grid. It is estimated that the initiative could earn schools involved an average of around £8,000 a year.

The government’s role would be in helping headteachers to crowdsource funds for the panels. Civil servants would also deal with linking up schools to the national grid and payments.

Gareth Thomas, a Labour MP mooted as a potential Labour candidate for London mayor in 2016, said the policy could help to free schools from reliance on the big six energy firms.

Thomas, who is promoting the policy as chairman of the Co-operative grouping of MPs within Labour, said: “Britain needs to expand community energy to give people more control over the energy they depend on. Helping schools to set up energy co-operatives to get a self-financing solar roof is a great way to spread understanding about sustainability.”

Friends of the Earth says that if every school installed solar panels the amount of energy generated would be the same as that used by 380,000 homes and would cut carbon emissions by the same amount as taking 110,000 cars off the road. A charity called Solar Schools is helping 66 schools raise a target of £851,000 and has crowdsourced half the target in six months.

The education sector represents a major potential market for the solar industry, as schools typically have large rooftops ideal for panels and rarely face planning difficulties. Current government regulations stop schools from borrowing to fund solar installations, even though ministers had said they wanted more solar panels installed on the roofs of public sector buildings.

Refrigeration, air-conditioning done cheaply by solar cooling system

Solar cooling system keeps water at 9 degrees Celsius for up to three months April 2, 2015 Source: Investigación y Desarrollo

Maintaining food in places where high temperatures prevail, using little energy at a low cost,  it is now possible with new technology, thanks to the creation of a solar cooling system.

Maintaining food in places where high temperatures prevail, using little energy at a low cost, it is now possible with Mexican technology, thanks to the creation of a solar cooling system designed by Susana Elvia Toledo Flores.

The prototype developed in the Research Department in Zeolites, at the Institute of Science of the Meritorious University of Puebla (BUAP), in center Mexico, works 24 hours and keeps the cold for up to three months.

The researcher developed the prototype in the Black Mountain Range of the state, where she has achieve to maintain water at nine degrees Celsius “with that temperature we can cool food, though the goal is to get as low as five, with this fish can be preserved without denaturing its proteins.”

The BUAP design is inexpensive, easy to manufacture and environmentally beneficial. “Normal cooling systems use chlorofluorocarbon chemicals that destroy the ozone layer and contribute to greenhouse gases, ours is friendly to the environment,” explains Toledo Flores.

It works with solar radiation and the cooling is achieved by means of a thermodynamic adsorption-desorption cycle lasting 24 hours. Methanol is used as a refrigerant and as zeolite (mineral) as an adsorbent.

Toledo Flores says the system has two stages, during the day “warming, desorption and the period of condensation happens. Solar energy heats the zeolite and increases the methanol vapor pressure, the refrigerant is condensed and stored in a tank flowing to the evaporator. ”

Overnight the cooling process is achieved, adsorption and evaporation period is performed. “The adsorbent bed temperature decreases after sunset, therefore, the refrigerant pressure is reduced and evaporates while the absorbent is cooled. During this period the coolant begins to evaporate and is again adsorbed by zeolite generating cooling temperatures of five degrees Celsius. The adsorption process continues all night until morning. ”

The equipment is composed of a solar collector, adsorbent bed, condenser and evaporator. To build it, the researcher calculates the amount of water to be cooled, thereby knows how many zeolite to use. She also considers the room temperature, in this case of 20 degrees Celsius.

Furthermore, the system “is not only designed to cool foods. It may also serve as an air conditioning, for example, in communities like Tecali de Herrera, Puebla, where there are areas without electricity and the system could adapt well to preserve their foods and medicine, bringing them better quality of life,” says Toledo Flores.

The project was presented at the International Congress of Solar Energy at Germany.

Solar panels on Israel’s parliament to save energy

Israel installs solar panels at parliament to save energy By Associated Press8:51 A.M.MARCH 29, 2015 JERUSALEM (AP) — Israel has installed solar panels on the roof of its parliament building, creating what it calls the largest solar field of any national assembly in the world.

The office of the parliament speaker says energy generated from some 1,500 solar panels will provide 10 percent of the electricity used at the Knesset, Israel’s parliament.

The Knesset is also advancing other energy-saving projects, like installing energy-saving lights, automatically shutting down lawmakers’ computers at the end of each workday, and using air conditioning systems to help irrigate the gardens surrounding the building.

The statement says the measures will reduce the Knesset’s energy use by a third.

Scientists will also conduct ecological research on the parliament roof.

The Knesset unveiled the solar field in a dedication ceremony Sunday.
