Denmark made a recent and very positive announcement. According to Denmark’s Energy Association, wind power is now the cheapest source of energy, beating coal, fossil fuels, and natural gas. What’s more, the government agency claims that by 2016, the electricity whipped up by its newest turbines will be half the price of conventional means. The announcement came in the last week of July, and is raising hopes for clean energy around the world.
For years, wind and solar have been achieving grid parity with fossil fuels in many places around the world, meaning they are just as cheap. But even without the tax breaks, declining manufacturing costs and growing scale have rendered wind power just as cheap as natural gas in many states in the gas-rich US. And as Deutsche Bank analyst Vishal Shah claims, this is the “beginning of the grid parity era” for solar, worldwide.
As he explains it, demand is being driven by “sustainable” markets – meaning the US, China, and regions outside of Europe – with Japan leading the way with an estimated 7 GW annual demand:
Solar is currently competitive without subsidies in 10+ major markets globally, and has the potential to achieve competitiveness in 10-20 additional markets over the next 3 years.
China, which plans to add 10 GW of solar capacity this year alone, only added “in the 2-3 GW range” during the first half of 2013, which would suggest a vast expansion is coming in the second half of the year. Emerging markets are likely to adopt unsubsidized policy models to promote solar growth, especially if new low-cost capital becomes available in concert with policy support to reduce costs.
But Denmark is blowing past grid parity and towards a scenario in which clean energy is actually much, much cheaper. According to analysts, when its two massive offshore wind farms come online, they’ll be the nation’s most inexpensive energy source by a wide margin. As Yale 360, an environmental policy group centered at the Yale School of Forestry & Environmental Studies, explains:
Electricity from two new onshore wind power facilities set to begin operating in 2016 will cost around 5 euro cents per kilowatt-hour. Wind power would remain the cheapest energy option even if interest rates on wind power projects were to increase by 10 percent, the report found.
This is good news for a nation that’s hoping to get 50 percent of its power from wind turbines by 2050. Right now, the nation already boasts an impressive clean energy mix of 43 percent. And Rasmus Peterson, Denmark’s energy minister, said at a press conference:
Wind power today is cheaper than other forms of energy, not least because of a big commitment and professionalism in the field. This is true for researchers, companies and politicians. We need a long-term and stable energy policy to ensure that renewable energy, both today and in the future, is the obvious choice.
Importantly, the DEA’s analysis did not factor in the health and environmental costs of burning fossil fuels—which are considerable—and instead looked directly at the market forces in the country. Natural gas and coal are much more expensive in Denmark than it is in the US, which helps make wind such an economic bargain, and the nation has explicitly pursued wind power for decades.
But improving technology, falling costs, and the strong, consistently blowing offshore winds that will turn the new turbines are making the case for wind power rock solid. At the end of July, it was revealed that Germany gets a full 28.5 percent of its energy needs with clean sources. Now Denmark is proving that running your nation on clean energy can be cheaper anyone thought possible, even ten years ago.

The prototypes still have several important kinks to be worked out as well. In tests, workers had a hard time negotiating sloping or slippery surfaces. And the prototypes cannot yet cope with twisting motions, so workers making turns while carrying heavy objects could tire out easily. But South Korea’s vast shipbuilding market is committed to merging human oversight with automation, and Daewoo is hardly alone in working towards this goal.
Though Coaltion forces are drawing down their presence in Afghanistan, Oshkosh’s and other unmanned ground vehicle concepts will likely be used in conflicts around the world in the years to come. Company representatives gave demonstrations of the technology at Eurosatory 2014, a defense industry trade show, and say they received positive feedback from other nations as well.
The applications seem wide, varied, and exciting, from combating diabetes to fighting cancer and HIV with surgical precision. And developments like these, though they measure in the billionth of meters, they add up to a future where lives are healthier, longer and more prosperous.
It has been a historic year, of that there is little doubt. And these two anniversaries are well-paired, drawing attention to two World Wars that were the most destructive in human history, but also inextricably linked. In total, some 90 million people died in both conflicts combined (thought estimates vary) and insisting that people remember how it all began is an opportunity to ensure that it never happens again.
At the closing ceremony of the AIDS 2014 conference a few weeks ago in Melbourne, Australia, many of the speakers – including longtime AIDS researcher and International AIDS Society Presidential Award winner Eric Goosby – told of how utterly terrifying the disease seemed 30 years ago. And while that fear is not gone, it has since diminished, replaced by and large with a sense of hope that the disease will be eradicated.
However, researchers from Temple University School of Medicine have found a way to cut the infected genes out, potentially eradicating the virus for good and negating the need for lifelong ARV treatment. The technique uses a DNA-snipping enzyme, a nuclease, and a targeting RNA strand to hunt down the genome and cuts the HIV-1 DNA from it. The cell is able to repair its own genomes, essentially sewing itself together again, only now HIV-free.
NASA addressed these goals and more two weeks ago with their mission to Mars panel at the 2014 Comic-Con. This event, which featured retired astronaut and living legend Buzz Aldrin, spoke at length to a packed room about how Apollo 11 represented the “the first Giant Leap”. According to Aldrin, the Next Giant Leap could be “Apollo 45 landing humans on Mars.”
So we can expect a lot more news and revelations about the Red Planet in the coming months and years. Who knows? Maybe we may finally find evidence of organic molecules or microbial life there soon, a find which will prove once and for all that life exists on other planets within our Solar System. And if we’re really lucky, we might just find that it could feasibly support life once again…
Inspired by the arctic eider duck, Energy Duck not only hopes to offer a unique renewable energy source, but also highlight the impact that climate change has had on the local population and breeding habitats of the eider duck in recent years. As its creators – Hareth Pochee, Adam Khan, Louis Leger and Patrick Fryer – explained:
All of this helps the Energy Duck overcome the all-important issue of intermittency. By being able to generate energy around the clock, the Duck is not dependent on the sun shining in order to continue operating and providing power. As the team explained:
The three-act story will start with a focus on Scott and his experiences, segueing into the lead-up to the event itself as it went viral and everyone scrambled to keep up with the momentum. The third act will focus on the event itself, which involved Miles rescuing a damsel in distress from the train tracks, stopping the Penguin from kidnapping the San Francisco Giants seal mascot, and getting the key to the city from the mayor.
