Not quite Scotland’s goal of 100% renewable energy by 2025, but still a highly ambitious one (relative to other countries), Denmark’s newest renewable energy target proposals aim to have wind supplying it with half of its electricity by 2020, and renewable energy supplying it with ALL of its energy by 2050. And all of its power and heat would come from renewables by 2035.
The Skydrain is an energy collection product that is focused on providing clean renewable energy to the existing sprawl condition and other urban sites.
Energy collection has been a major topic for quite sometime, but during the past decade the idea of using renewable energy resources has began to play a major role in the energy collection discussion. The “green movement” has taken off quite rapidly, and tends to have the biggest impact when gas prices increase. However, we as a society are still wasteful in terms of energy, and our dependence on oil is still very strong. The question of how to lessen our use of oil is not just solved by driving electric cars and installing solar panels, but rather by changing people’s perceptions on how energy is collected and how energy works. The Skydrain takes this issue on directly. It is designed to engage the public on a level that no other “green product” has done before.
Ethiopia isn’t a country that comes up often when discussing renewable energy, but the Ethiopian Electric Power Coroporation (EEPCO) this past week announced it’s starting construction of six wind power projects and one geothermal power plant. In total, electricity generation capacity for the renewable energy projects totals more than one gigawatt (1 GW), Ethtiopian news service NewsDire reported.
The renewable energy projects are part of EEPCO’s plans to increase national electricity generation capacity five times by 2015, from a current 2000 megawatts (MW) to about 10,000 MW. Increasing electricity generation, in turn, is key to the government’s broader economic development plans.
People understand the importance of energy conservation and therefore are gradually opting for methods in which natural and renewable resources of energy are implied for generating power. Everything inside our homes, from your cooking appliances to A/V devices to lighting fixtures, is going green these days. Have you ever considered the idea of having a green roof for your home? There are a numerous methods that can be implied on the roofs of the homes to make them green, which will not only help cut down on the electricity bills but will also make your home an eco-friendly and an eye-pleasing appearance. Let’s take a look at some of the interesting green options for your rooftop after the jump.
Scotland has an ambitious and admirable goal: 100% renewable energy. Taking steps toward reaching this goal, the Scottish government approved an offshore test site for a new 6MW wind turbine.
2-B Energy, based in the Netherlands, has permission to install an innovative two-bladed wind turbine approximately 70 feet off the coast of Methil in Fife, according to Scottish energy minister Fergus Ewing. 2-B is one of several companies which has a lease in the 2010 offshore wind demonstration leasing round, which is supposed to help develop wind farms offshore and in deep water.
There have been a lot of articles about how many Asian countries, namely China, are starting to dominate the solar energy sector. However, General Electric Co. has decided to enter the Asian alternative energy sector by announcing they will be providing 31 turbines for a $100 million wind farm in Mongolia. The farm will be built by Newcom LLC, a Mongolian investment company.
You would have heard of various wind turbine projects that run toward the generation of power by using the naturally blowing wind’s energy. This generated power is then used to run several applications that require electrical energy as an input. For that purpose, the energy is generally transported and fed into the power grid. But, here is a unique and power-packed German design for an integrated wind turbine structure that is termed as Efflux. There are various unique features of this pylon that take its efficiency level to newer heights when compared to the regular wind turbine structures. You would be wondering what is the addition to this pylon that makes it different from other similar structures! Then, check out some of the exclusive characteristics of this power producer.
In a few places, wind power is already as cheap as natural gas or coal-fired electricity. By and large, however, it’s still a bit more expensive in most regions ’round the world. But not for long.
Climate Progress points us to this report in Bloomberg New Energy Finance, which has the scoop: “The cost of electricity from onshore wind turbines will drop 12% in the next five years thanks to a mix of lower-cost equipment and gains in output efficiency.”
And that 12% drop will have huge implications, as Bloomberg reports: “The best wind farms in the world already produce power as economically as coal, gas and nuclear generators; the average wind farm will be fully competitive by 2016.”
Marine energy has long looked to be a niche area, capable of meeting just a few percent of global power demand. But this seemingly limited energy source is drawing some big players, the latest being Siemens. The German engineering giant boosted its stake this month in Bristol, U.K.-based tidal energy developer Marine Current Turbines from under 10 percent to 45 percent. The attraction, according to Michael Axmann, chief financial officer for Siemens’s solar and hydro division, is the predictability of marine power.
Solar and wind farm operators struggle to predict tomorrow’s output, and bad forecasts can wreak havoc with power transmission planning and market prices. In contrast, the gravitational pull of the moon and sun that controls tidal cycles provides a sure means of anticipating the output from tidal generating stations. “Power output of the systems could be calculated for centuries in advance,” says Axmann.
Flying a kite has often been considered child’s play, but a group of inventors think the concept could be used to make wind energy cheaper and more reliable than ever before, potentially revolutionizing wind power forever.
energyNOW! correspondent Josh Zepps met the innovators working to turn the idea of flying a kite into an airborne wind turbine that’s lighter and more powerful than traditional wind turbines. The full video is available below:
