Solar PV Internal Costs

This article will gather some data about TEC community views on the global average internalized cost of distributed solar PV energy. Please add your opinion so we can gather a statistically significant sample and get a meaningful indication of the consensus (or lack thereof).[read more]

It Was $40 Billion Cheaper to Install 32GW of Solar Globally in 2013 than in 2012

November 25, 2014 by Stephen Lacey

Solar Install Pricing Drop

Between 2012 and 2013, global investment in climate change mitigation and adaptation dropped $28 billion. When scientists say we need a dramatic surge in zero-carbon energy sources, the drop seems like bad news. It's certainly not good by climate action standards. But it's not as bad as it sounds either.[read more]

The World's First Rural Feed-In Tariff?

Rural Feed-In Tariffs

How do we move clean energy access beyond just a light bulb? With millions of dollars in new investment capping a record year for beyond the grid solar markets, that's the question many are now asking. This record investment is building markets.[read more]

SunEdison, TerraForm Buy First Wind For $2.4B to Become Renewable Project Giant

November 23, 2014 by Eric Wesoff

SunEdison and its YieldCo Teraform acquired wind developer First Wind for $2.4 billion. Now SunEdison is in the wind business and can add wind projects to the solar project pipeline of its YieldCo, TerraForm. The purchase price was comprised of $1.9 billion in an upfront payment and a $510 million earn-out.[read more]

SunPower Is Tripling Solar Capacity, Boosting Cell Efficiency, Adding Energy Management and Storage

November 21, 2014 by Eric Wesoff

SunPower acquired SolarBridge, an Austin, Texas-based VC-funded integrated microinverter startup. SolarBridge has a high-performance, premium-priced inverter that is a good match for the industry's highest-efficiency solar module from SunPower.[read more]

Friday Energy Facts: Solar Photovoltaic Output Depends on Orientation, Tilt, and Tracking

PV Positioning and Efficiency

Because PV panels are able to capture more solar energy when they are pointed directly at the sun, installers may configure systems to optimize output by adjusting the orientation and tilt of a system, or by using mechanisms that track the sun as it traverses the sky.[read more]

Clean, Distributed Energy Can Benefit Low-Income Families

Clean Energy and Poverty

How will clean energy policies affect low-income families and communities of color? This is a critical question to answer because low-income families, including a disproportionately large percentage of African Americans and Latinos, spend a greater portion of their income on utility bills.[read more]

Renewable Business Acquisitions Continue in Australia

November 20, 2014 by Nigel Morris

Over my years in renewables, I’ve lived with and installed a range of technologies including the odd small wind turbine. I’ve visited properties where committed owners have installed these devices appropriately and have enjoyed low cost reliable energy without a power line in sight, for decades.[read more]

Getting Cleantech Through its Awkward Teen Years

November 18, 2014 by Matt Stewart

Cleantech and the Mainstream

Not so long ago, cleantech was mired in a troubled childhood. Efficiency bored people into a coma, solar was expensive. Some companies accepted government support, some failed, providing fodder for political attack. Cleantech was a dirty word. Just think Solyndra. Now the pendulum has swung back.[read more]

How to Clean All Those Solar Panels? Get Robots to Do It

November 15, 2014 by Christina Nunez

Solar Panel Maintenance

With abundant sunlight and plenty of open space, deserts are an obvious place to put large solar arrays, but there’s a downside: lots of dust, and not enough rainfall to wash it off. A buildup on solar panels can reduce efficiency by anywhere from 7 to 40 percent, according to various research efforts.[read more]

Are Housing Regulators Quietly Dropping Their Opposition to PACE?

November 15, 2014 by Stephen Lacey

The Federal Housing Finance Agency, the government entity responsible for regulating America's multi-trillion-dollar secondary mortgage market, is reportedly easing its opposition to local programs that allow homeowners to pay for renewable energy and efficiency retrofits through their property taxes.[read more]

Utilizing GIS for Renewable Energy Projects

November 15, 2014 by Dan Liggett

GIS and Renewables

Your renewable energy infrastructure projects are far too expensive to make random decisions on siting. For many reasons – not the least of which are cost, efficiency and productivity – siting should be as exact as the science behind renewable energy itself.[read more]

Shedding Light on the Future of Photovoltaics

November 13, 2014 by Energy @ MIT

Future of PV

Several government agencies, academic researchers, and firms have proposed scenarios for the future in which photovoltaic (PV) technologies grow rapidly. To support such growth, PV technologies would need to be developed with resource constraints in mind.[read more]

KiOR in Default on Loan

November 12, 2014 by Robert Rapier

During the administration of former Republican Governor Haley Barbour, the state of Mississippi provided a $75 million no-interest loan to advanced biofuel company KiOR (OTCMKTS: KIOR) to build a plant in that state. Last Friday KiOR was supposed to make a $1.875 million payment on the loan.[read more]

Nuclear and Renewables Shared Goal and Comparative Costs
