Denmark Aims for 100 Percent Renewable Energy

Denmark Aims for 100 Percent Renewable Energy | Sustainable Energy | Scoop.it
Denmark, a tiny country on the northern fringe of Europe, is pursuing the world’s most ambitious policy against climate change. It aims to end the burning of fossil fuels in any form by 2050 — not just in electricity production, as some other countries hope to do, but in transportation as well.

Renewable Energy Momentum Has Passed The Tipping Point

Renewable Energy Momentum Has Passed The Tipping Point | Sustainable Energy | Scoop.it
This is a great summary piece on the renewable energy revolution from one of CleanTechnica’s daily readers. Unlike with many of the recent reader articles we’ve published, this one doesn’t come from a frequent commenter but from one of the many, many lurkers who read CleanTechnica daily and silently. I’m happy he jumped in with

Record streak for low power prices in Germany

Record streak for low power prices in Germany | Sustainable Energy | Scoop.it
In the 100 days since 1 April 2014, the wholesale power prices in Germany was below four cents on 77 days. At present, there is the longest streak of consecutive days this year. But the biggest finding is probably the far lower power prices in France..

Rooftops, Energy Storage, and IOU Business Model

Rooftops, Energy Storage, and IOU Business Model | Sustainable Energy | Scoop.it

The crux of the problem is a positive feedback loop that raises utility rates as more customers produce more of their own power.  They use less power from the grid, and so the fixed costs of transmission, distribution, and generating assets must be recovered over a shrinking base  That drives up rates and gives customers that much more incentive to produce their own power.  Moreover, the fixed costs themselves increase, as the shrinking demand for kilowatt-hours torpedoes credit ratings and raises the IOU's cost of capital.  The end result could ultimately be wholesale bankruptcy.

Predicting the Impact of Renewable Energy

Predicting the Impact of Renewable Energy | Sustainable Energy | Scoop.it

I couldn’t make this year’s Renewable Energy Finance Forum – Wall Street, though I did peruse the notes that my colleague Tom Konrad of AltEnergyStocks forwarded to me.  Among the many details, I noticed this rather broad statement: “Historically, we have under-predicted.”  He went on to explain: “NREL’s 1998 prediction of the penetration of renewables for 2020 was only 30% of  the 2013 number.”  In other words, we’re headed to beat the expectation for 2020 by an enormous margin.

How Crowdfunding Solar is Keeping the Lights on in Detroit

How Crowdfunding Solar is Keeping the Lights on in Detroit | Sustainable Energy | Scoop.it

As the costs of solar technologies decrease, the opportunities for innovative solutions to community problems are increasing. Economic hardships have hit America’s communities hard and, in many communities, electricity prices continue to rise as spending on local public services continues to fall. From 2010 to 2011, the state and local sectors contracted by 3.4 percent, the largest contraction since World War II and that contraction continues to be felt in neighborhoods across the country. Spending cuts have come in all shapes and sizes; some cities have reduced the local police force, while others have slashed the budgets for local fire departments.

Surcharge on self-consumption deferred

Surcharge on self-consumption deferred | Sustainable Energy | Scoop.it
After a somewhat rushed and hasty legislative process, revisions to the German Renewable Energy Act (EEG) went into force on August 1st. One of the more controversial amendments is the introduction of a surcharge on self-consumption of locally generated solar power. Now, the transmission grid operators (TSO) have announced that they'll defer the collection of this surcharge until further notice..

German power exports still more valuable than imports - 100% renewable - Renewables International | Sustainable Energy | Scoop.it
Last year, the electricity Germany exported was 6.3% more valuable per unit than the power it imported – the exact opposite of the narrative that Germany is dumping excess renewable electricity on neighboring countries at low cost. France faces a particularly dire imbalance financial; German electricity is 24.4 percent more valuable..

Complete Renewable Energy Goal Announced

Complete Renewable Energy Goal Announced | Sustainable Energy | Scoop.it

The Global Alliance for 100% Renewable Energy recently called on European leaders to make firmer commitments to make a transition to renewable energy. The statement was made during the inauguration of the Alliance in Munich when member organizations stated that renewable energy has become the key to Europe’s future economic and industrial development.

The alliance highlighted “there is still a huge gap between the overwhelming socio-economic and environmental benefits of renewable energy and the political will to set adequate targets.” Members of the Alliance include the World Future Council, Fraunhofer Institute for Solar Energy Systems ISE and World Wind Energy Association. They called for regional, national and European wide 100% renewable energy targets within the next four decades.

Solar Energy and Durability Testing

Solar Energy and Durability Testing | Sustainable Energy | Scoop.it

This first report covered tests of five of 2012′s top eight crystalline silicon PV modules, from among SunPower (SPWR), Suntech (STP), Yingli (YGE), Trina (TSL), Canadian Solar (CSIQ), Sharp (SHCAY), Hanwha SolarOne (HSOL), and Kyocera (KYO).

The results showed “a substantial spread in thermal cycling durability, while all tested module types proved very good stability in the damp heat/UV test sequence.” And though some participants wanted to remain anonymous, all the data acquired under the PVDI will continue to be used to provide a comprehensive comparison in years to come.

Hans De Keulenaer's insight:

Since the massive use of solar photovoltaics is a relatively recent trend, there is little information on the long-term performance of PV panels. This report provides a welcome piece to the sustainable energy puzzle.

Concern about emissions trading scheme affecting the impact of renewables

Concern about emissions trading scheme affecting the impact of renewables | Sustainable Energy | Scoop.it

Deep problems in Europe’s carbon trading scheme – its flagship climate change policy – are set to cancel out over 700m tonnes of emissions saved through renewable energy and energy efficiency efforts, according to a new report.

The study, by carbon trading thinktank Sandbag, found that a huge oversupply of carbon pollution permits means many are being banked to enable emissions after 2020, when efforts to tackle global warming should be intensifying. These emissions, nearly equivalent to Germany’s annual carbon pollution, will cancel out efforts made in other areas to cut carbon.

The report also warns that Europe’s emissions trading scheme (ETS) is a “global dumping ground” for “dubious” carbon permits created by projects around the world.

Utilities fear what they cannot control with community solar

Utilities fear what they cannot control with community solar | Sustainable Energy | Scoop.it

Utilities love solar. Or at least they love utility-scale solar, i.e. installations they can own or control through power purchase agreements. But as the battle with net energy metering has shown, utilities fear what they cannot control.

Some states and some utilities have embraced community solar, particularly in the western United States. No surprises there. Colorado, thanks in part to its Solar Gardens Act, has seen community solar flourish.

It will be interesting to see if utilities try to corner more of the solar market with tools like on bill financing or if they fight to their demise.
