Skyscrapers could soon generate their own power, thanks to see-through solar cells



A solar window created by scientists at Michigan State University in East Lansing reached an efficiency of 5% using organic photovoltaics.

Lance Wheeler looks at glassy skyscrapers and sees untapped potential. Houses and office buildings, he says, account for 75% of electricity use in the United States, and 40% of its energy use overall. Windows, because they leak energy, are a big part of the problem. "Anything we can do to mitigate that is going to have a very large impact," says Wheeler, a solar power expert at the National Renewable Energy Laboratory in Golden, Colorado.

A series of recent results points to a solution, he says: Turn the windows into solar panels. In the past, materials scientists have embedded light-absorbing films in window glass. But such solar windows tend to have a reddish or brown tint that architects find unappealing. The new solar window technologies, however, absorb almost exclusively invisible ultraviolet (UV) or infrared light. That leaves the glass clear while blocking the UV and infrared radiation that normally leak through it, sometimes delivering unwanted heat. By cutting heat gain while generating power, the windows "have huge prospects," Wheeler says, including the possibility that a large office building could power itself.

Webinar: Building Markets: Energy Storage in Massachusetts and Offshore Wind in Rhode Island

August 9, 2018


1:00pm — 2:30pm ET


This webinar highlights two winning programs from CESA’s 2018 State Leadership in Clean Energy Awards: Massachusetts’ Advancing Commonwealth Energy Storage (ACES) Program, and Rhode Island’s Block Island Offshore Wind Farm.  

In Massachusetts, the Advancing Commonwealth Energy Storage (ACES) Program was created to jump-start the state’s energy storage industry by piloting innovative, broadly replicable energy storage demonstration projects with multiple value streams, thereby priming Massachusetts for increased commercialization and deployment. ACES will demonstrate nine storage use cases to accelerate the adoption of storage technologies, provide benefits to customers and utilities, and highlight market and regulatory barriers. The 26 demonstration projects supported by the ACES program will collectively add 32MW/83MWh to the grid where only 4MW/7MWh currently exists.

Webinar: The Future of Electrification and What It Means for Clean Energy

Tuesday, June 26, 1-2pm ET 
 
 
There is great potential for electricity to replace liquid and solid fuels for transportation, industrial processes, agriculture, and heating and cooling. In April the Electric Power Research Institute (EPRI) published the U.S. National Electrification Assessment, which examines four possible pathways of how electrification could proceed in the coming years and decades. In the report’s most ambitious scenario, electricity's share of total energy supply would rise from 19 percent today to 50 percent by 2050.
 
In this webinar, Francisco de la Chesnaye, Senior Program Manager at EPRI, will present the report’s findings and discuss the potential implications for state renewable energy initiatives. There will be opportunity for audience questions.

Australian solar plant to have world's largest power storage capacity

TOKYO -- A roughly $1 billion solar energy project in Australia will employ one of the biggest power storage facilities in the world, with Japanese and Western companies contributing funds.

As part of this, a 250-megawatt plant in the state of South Australia will use a 100MW lithium-ion battery storage system. The storage capacity will be on par with a wind farm battery system from Tesla in Australia, now the largest of its kind on the planet. Power generated at the forthcoming plant will be sold to local utilities.

Secretary of Energy Rick Perry Announces $68.5 Million for Advanced Vehicle Technologies Research




WASHINGTON, D.C. - Today (May 1), U.S. Secretary of Energy Rick Perry announced up to $68.5 million in available funding for early-stage research of advanced vehicle technologies that will enable more affordable mobility, strengthen domestic energy security, and enhance U.S. economic growth.

“Transportation is fundamental to the American way of life,” said Secretary Perry. “Investing in early-stage research of advanced transportation technologies can give families and businesses greater choice in how they meet their mobility needs while reducing energy costs and making our transportation more efficient and reliable.”

Funded through the Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy, projects selected through this Vehicle Technologies Office funding opportunity will address priorities in advanced batteries and electrification, including cyber security related to electric vehicle charging; materials for both lighter weight vehicle structures and advanced powertrains; technology integration and energy-efficient mobility systems; and engines and fuels, including technologies for off-road applications as well as the co-optimization of engines and fuels.

Aging Wind Farms Are Repowering with Longer Blades, More Efficient Turbines

Old wind farms that have towered over the same fields for more than a decade may be generating more power now than ever before.

As America's biggest wind farms age, their owners are starting to "repower" them with more efficient turbines, new electronics and longer, lighter blades that can sweep more wind with each rotation. The result is a thriving new industry, new jobs and more renewable energy.

What makes a wind turbine break? NREL's drivetrain experts want to know.

One way to reduce the cost of #wind energy is to understand how to keep a wind turbine operating smoothly. Check out how researchers at the National Renewable Energy Laboratory are investigating the likely causes of premature drivetrain failure.
