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.
Now a question is coming into focus: Can Denmark keep the lights on as it chases that lofty goal?
Lest anyone consider such a sweeping transition to be impossible in principle, the Danes beg to differ. They essentially invented the modern wind-power industry, and have pursued it more avidly than any country. They are above 40 percent renewable power on their electric grid, aiming toward 50 percent by 2020. The political consensus here to keep pushing is all but unanimous.
Their policy is similar to that of neighboring Germany, which has spent tens of billions pursuing wind and solar power, and is likely to hit 30 percent renewable power on the electric grid this year. But Denmark, at the bleeding edge of global climate policy, is in certain ways the more interesting case. The 5.6 million Danes have pushed harder than the Germans, they have gotten further — and they are reaching the point where the problems with the energy transition can no longer be papered over.
The controversial government program that funded failed solar company Solyndra, and became a lighting rod in the 2012 presidential election, is officially in the black.
According to a report by the Department of Energy, interest payments to the government from projects funded by the Loan Programs Office were $810 million as of September - higher than the $780 million in losses from loans it sustained from startups including Fisker Automotive, Abound Solar and Solyndra, which went bankrupt after receiving large government loans intended to help them bring their advanced green technologies to market.
The report's findings are more of a political victory than a financial one. It took the program three years to break even after Solyndra's failure, while during that same time the Standard & Poor's 500 index increased 67 percent.
Still, the federal loans program is a success for taxpayers, judging by the numbers in the new report, the DOE said. After Solyndra's 2011 collapse, the program was sharply criticized by Republican lawmakers as a waste of public money and a fountain of cronyism. The outcries mounted as others in the program failed, and the DOE issued no new loans between late 2011 and this year.
"Taxpayers are not only benefitting from some of the world's most innovative energy projects... but these projects are making good on their loan repayments," Peter Davidson, executive director of the Loan Programs Office, said in an interview on Wednesday. Davidson took over the loan program in May of 2013.
When considering hybrid systems composed of photovoltaic solar panels, geothermal, hydro or wind turbines, the whole is greater than its parts, but you need to understand the best type of energy generation that can be used in your area.
The Enphase system intelligently integrates the critical technologies needed to solve solar energy challenges at scale: smart grid intelligence, communications, big data analytics and storage.
AltEnergyMag.com has once again partnered with SPI 2014 to bring all the industry news and exciting new products to help our readers make sense of this key tradeshow. Here we have compiled a list of some product releases from this years show.
Here are press releases and announcements from SPI 2014. Exhibitors are welcome to post their news here too.
For SPI in 2014, we will be introducing the all-new control capabilities of our OPTICS RE user application. Launched this spring, the OPTICS RE cloud-based user-interface application provides installers and owners of OutBack systems the ability to easily monitor PV/solar system operation, performance and output via an intuitive dashboard from any Internet-enabled device.
SPI does a good job of organizing the business areas of interest in a logical manner making it easier to focus on those areas that are important to our business.
The current power trade between the United States and Mexico is relatively small, and the renewable sector in Mexico remains underdeveloped. Yet, encouraging market dynamics gives ample reason to pay attention to this area.
The experts from TÜV SÜD underline how comprehensive due diligence can prevent investments from being ‘gone with the wind'.
Innovative Ontario companies find energy savings in places they'd least expect
In this paper, we will focus on a theoretical study and its application to a concrete site. We will try to answer the question: How can we optimize the implementation of horizontal trackers on a solar plant?
Going solar should be a great experience - not a headache, and doing your homework upfront will give you something money can't buy - peace of mind.
This year Solar Power International has moved to October. SPI is perhaps the most important show for the solar industry here in North America. Stay tuned for the AltEnergyMag SPI 2014 special newspage devoted to news specifically from the show.
Installers working on a tile roof must deal with particularly difficult challenges. Tile roofs are manufactured from many types of materials, including clay, zinc coated aluminum, concrete, wood and fiberglass, all of which come in a wide range of shapes and sizes. Installing solar panels on a tile roof takes more time than traditional asphalt shingle roofs and often requires additional framing.
