through a new deal with Arizona utility Arizona Public service. IO President Anthony Wanger said that the new offering came
as a result of clear call by our customers to use cost-effective clean energy to power their data centers.
and it has a mandate to deliver 15 percent of its electricity from clean energy by 2025.
APS has contracted to buy all of the 280 MW of solar energy from the Solana solar thermal plant 70 miles southwest of Phoenix. That could provide enough solar electricity for 70
when it comes to the residential solar panel industry. As clean energy options get cheaper starting with large utility solar farms,
and wind farms more companies that offer colocation and cloud services will be able to afford to offer clean energy options to customers.
While Amazon has been one of the quietest on this front, it has committed more recently to 100 percent clean energy,
starting with using wind to power a data center in Indiana. Wind is the cheapest clean energy option
but is only available at scale in certain areas of the U s. Recently IO decided to split itself into two companies,

#Roll to roll manufactured decorative solar panels to be 10 times cheaper Based on printing technologies, VTT Technical Centre of Finland has developed
and utilized a mass production method allowing the manufacturing of decorative, organic solar panels. Freedom of design increases the range of panel applications on the surfaces of interior and exterior building spaces.
VTT is also studying the feasibility of printing technology in the mass production of solar panels made from inorganic perovskite materials.
The new mass production method enables to create interior design elements from organic solar panels (OPV, organic photovoltaics) harvesting energy from interior lighting or sunlight for various small devices and sensors that gather information from the environment.
The solar panel manufactured with VTT gravure and screen printing technologies is only around 0. 2 mm thick,
VTT is also currently examining how well the roll-to-roll printing methods are suited to the manufacturing of inorganic solar panels made from perovskite materials.
The first perovskite solar cells manufactured in the laboratory using solution-based processes have been promising. The performance of this solar cell is roughly five times better than that of an organic photovoltaic cell,
and the material costs can be even ten times lower. Freely designed decorative organic solar panels are applicable also in indoor use to harvest energy from indoor Light production methods are cost-effective
and materials can be recycled after the use. New materials such as perovskite can be printed with same methods and increase efficiency in future.
The research scientists have tested the feasibility of the method by printing leaf-shaped photovoltaic cells. Active surface of a one leaf is 0 0144 m2
Two hundred OPV leaves make one square metre of active solar panel surface that generates 3. 2 amperes of electricity with 10.4 watts of power at Mediterranean latitudes.
Organic solar panels are flexible and light, but their efficiency is lower compared to conventional, rigid silicon-based solar panels.
The solar panels are manufactured with printing machines based on conventional printing methods using the roll-to-roll method,
which enables the rapid mass production of the products: the printing machine can produce up to 100 metres of layered film per minute.
The market for organic photovoltaic cells is developing, with a market breakthrough expected within three years.
VTT is also developing a method to utilize light in wireless data transfer by using solar cells as data receivers.
This will open new application possibilities to utilize printable solar cells e g. in Iot (Internet of things) type applications, in

##Solar is now the second largest source of new electricity capacity in the U s.,behind natural gas,
It is also thanks to advancements in solar technology which brought costs down, and innovative new forms of financing that make#going solar more affordable for consumers.#
#Companies like Vivint, Solarcity and Sunrun have raised all upwards of $500 million to finance residential solar projects around the country.
#Tesla batteries are powering an energy revolution Solarcity generator Tesla motors lithium-ion battery packs aren t just powering electric luxury sports sedans for wealthy any more.
They ve started#appearing in a small number of California homes to store electricity generated by rooftop solar panels,

#A big box retailer like Walmart could charge up a Tesla battery pack with cheap energy produced by its Solarcity rooftop photovoltaic array
and then tap that power when demand##and electricity rates##spike. That would let them minimize paying their local utility high##demand charges##for electricity
when they need it most. And the cost of the Solarcity s system, called Demandlogic?
Effectively zero, according to Solarcity, since the monthly payments for energy storage would be less than the money saved by not forking over cash to the utility.
And if that sounds like a threat to century-old monopoly utilities, it is.####Our business model is to become the energy company of the 21st century,
##Solarcity chief executive Lyndon Rive told#The Atlantic.####You re still connected to the grid but the grid would be your secondary provider
such as those in California and parts of Massachusetts and Connecticut where Solarcity is offering Demandlogic.
And to get the Tesla battery pack you have to sign up for a solar array, which means only businesses with low-rise buildings and flat roof##retailers,
allowing them to store electricity from the grid when rates are low and use that power
While Stem is a startup the utilities should be particularly wary of Solarcity and its partnership with Tesla motors.
Tesla chief executive Elon musk serves as Solarcity s chairman and is Rive s cousin.)Tesla and Solarcity s combined market cap##$21. 3 billion##exceeds that of the parent companies of Pacific gas & electric and Southern California Edison, the two big California utilities
whose customers Rive covets. And Solarcity is pioneering#the securitization of solar##giving it the ability to dip into a potentially vast pool of capital by packaging leases for photovoltaic systems into asset-backed notes that are sold to pension funds,
hedge funds and other deep-pocketed investors. Rive says Demandlogic should save commercial customers 20 percent in demand charges.
The system s algorithms constantly monitor electricity supply and demand charging and discharging the battery to minimize drawing expensive electricity from the power grid.
The size of the battery pack will be customized for each business but would be able to store roughly 30 percent of the electricity generated by the solar array.
And the Tesla batteries provide backup power if the grid goes down in an earthquake
but intermittent electricity are generated by wind and solar farms. Lithium-ion batteries remain expensive and Rive and Solarcity spokesman Jonathan Bass was sketchy on the details on how the economics pencil out
when providing energy storage to customers for no money down. But growing economies of scale are in Solarcity and Tesla s favor.##
##In places with high costs of electricity, I think you ll see up to 50 percent of solar systems will have energy storage,

Meanwhile, in Arizona yesterday, the state s utility regulator turned back a request by Arizona Public service (APS) to#impose steep new fees on homeowners who install solar panels#on their roofs.
As more customers generate their own electricity utilities face declining revenues while still retaining responsibility for paying for the transmission system.
In Arizona, for instance, there were 900 solar arrays installed on Arizona residential rooftops in January 2009. By June of this year, that number had grown to 18,000 with 500 more photovoltaic systems being installed each month.
homeowners receive a credit for the solar electricity they send to the grid that is used to pay for the power they use

#Germany generates 74%of power needs from renewable energy Germany impressive streak of renewable energy milestones continues, with renewable energy generation surging to a record portion nearly 75 percent of the country overall electricity demand
electricity prices actually dipped into the negative for much of the afternoon, according to Renewables International. In the first quarter of 2014, renewable energy sources met a record 27 percent of the country electricity demand,
thanks to additional installations and favorable weather. enewable generators produced 40.2 billion kilowatt-hours of electricity,
up from 35.7 billion kilowatt-hours in the same period last year, Bloomberg reported. Much of the country renewable energy growth has occurred in the past decade and,
as a point of comparison, Germany 27 percent is double the approximately 13 percent of U s. electricity supply powered by renewables as of November 2013.
it was demonstrated that a modern electricity system such as the German one can already accept large penetration rates of variable but predictable renewable energy sources such as wind and solar PV power,
via email. n fact there are no technical and economic obstacles to go first to 20 percent of annual electricity demand penetration rate from a combination of those two technologies,
the price of commercial solar power is now equal to retail electricity rates. And wind power reached record output levels last year producing a massive 25.2 GW
