This article deals with the present energy mix and tries to discover how the future energy mix should look in order to be sustainable and significantly reduce environmental impact, for example reduced CO2 emissions. It should be less dependent on the fossil fuels, have increased reliability, have fuel cost with reduced price fluctuations and be able to successfully meet the future demand for energy that just gets larger and larger as world energy requirements increase with the new lifestyle choices.
The US has installed over 25 gigawatts of wind, and thanks to hodge-podge of policy incentives, research and development, and private investment wind has become the poster-child of renewable energy and at the utility-scale has achieved grid-parity with conventional fossil-fuel energy. However not a single kilowatt of offshore wind has been developed, despite it being a stronger and more consistent energy source than its counterpart on land, closer to large populations where the energy is needed, and already proven commercial technology.
"Buildings like trees, cities like forests." When Michael McDonough, author and sustainability architect, suggested this be the new paradigm for the future, he was referring to the creation of buildings and communities that are self-sufficient. He also reminds us that "waste is a human phenomenon", so the concept of recycling and efficiency is central to the attainment of environmental stewardship. Through integration, energy management, efficiency techniques and technologies it is now possible to create buildings that are 'greener' and more ecologically synergistic than ever before.
Here is a short summary of some of the hot stories reported on in the last month or so.
Wind power development doesn't deal with a single industry. There are steel workers, engineers, precision manufactures, boat builders, construction crews, composite technologies, and marine technologies. The Maine Wind Industry Initiative brings these partners under one roof, so that they can network and solve problems working together.
As the PV business continues to grow, new backsheet constructions are continually being introduced. But the products we use in our efforts to be more sustainable have a bigger footprint than we think. Currently, there are at least ten commercial manufacturers of traditional PV backsheets, with traditional products in the development stage. Traditional backsheets, the protective covering on solar cells, are produced mainly from polyester and Tedlar films. Polyester is made from petroleum and Tedlar is solvent-cast using DMAC, a highly toxic industrial solvent. Both of these products defeat the purpose of clean, green energy, and as the demand for solar energy increases, so does this issue.
The Elithis Tower, designed and constructed as the world's most environmentally sound building, has just been unveiled. Touted as the first positive energy office structure, the tower creates more power than it uses. Designed and constructed at equal cost to a traditional building, the 54,000 square foot structure produces six times fewer greenhouse gas emissions. To achieve this impressive combination, a complete environmental ideology was designed.
In a true sign of the times, earlier this month, Ford struck a deal to sell their entire Wixom, Mich.plant to two companies focused on the creation and storage of alternative energy. According to Ford officials, the plant is being sold to Xtreme Power of Austin, Texas, and Clairvoyant Energy of Santa Barbara, Calif., for $725 million and will be redeveloped as a renewable energy park. The Wixom project is expected to create about 4,000 jobs.
Shares of A123 Systems, one of just a handful of U.S.-based makers of batteries for electric cars, debuted sharply higher from its offering price Thursday as investors cheered the closely-watched firm. The firm is one of just a few American companies that are competing with much larger Asian rivals for the potentially lucrative hybrid and plug-in electric car battery market. As the battery is the most expensive component in an electric car, the thinking goes that whoever controls the battery market may ultimately control the auto industry.
Few nations are better positioned -- or motivated -- to fuse the fight against recession and global warming than Spain. The country is already a leader in renewable fuels through $30 billion in public support and has been cited by the Obama administration as a model for the creation of a green economy. Spain generates about 24.5 percent of its electricity through renewable sources, compared with about 7 percent in the United States. But with unemployment at 18.5 percent, the government here is preparing to take a dramatic next step. Through a combination of new laws and public and private investment, officials estimate that they can generate a million new green jobs over the next decade.
Yeah, that doesn't sound so great given the current limited range of EVs, but solar installer SolarCity has decided to lend a hand and has built a set of four solar electric-car charging stations along U.S. Route 101 . SolarCity is calling the project the world's first solar-powered electric-car charging corridor. Each station comes equipped with a 29-kilowatt solar-power system that's connected to the electrical grid, so that drivers can charge their vehicles even when the sun isn't shining. The stations are fast-charging, meaning that they feed electricity into the vehicles more speedily than standard wall outlets. But they still will take more than three hours to fully charge an electric car.
Panasonic is set to release the EverLed series of light bulbs-the most efficient LEDs ever produced- next month in Japan. The bulbs use 1/8 the power of an incandescent and are said to get up to 19 years of burn time. They will retail for roughly $40 US and use only 85 lumens per watt for 40W bulbs and 82.6 lm/W for the 60W bulbs so the cost to run one could be as low as $2 per year when their 19-year lifespan is taken into account.
US wind turbine manufacturer Clipper Wind Power will build a plant in the North East of England to manufacture blades for its planned 10 MW offshore turbines with the help of a government grant. Clipper will occupy the new 4,000 m2 facility, which will be situated on the River Tyne, from the start of April 2010, and the plant will employ 60 people by the end of the year. The government's Department of Energy and Climate Change (DECC) today announced an award of £4.4 m under its Low Carbon Energy Demonstration (LCED) capital grants scheme for the project, which it hopes will kick-start a domestic turbine industry for the UK offshore market. A fully operational Clipper 10 MW turbine will stand at 175 meters in height, while each blade will be more than 70 meters long and weigh over 30 tonnes.
Subterranean Solar, or SubSolar, is a unique and innovative system of utilizing "subterranean solar panels" to gather solar power. No unsightly above ground solar panels need to be used anymore. How Does It Work? A compact optical device is installed upon a rooftop or other sunlight-catching environment. This optical device captures and magnifies the sun`s rays and transfers the sunlight from its linear or cylindrical lenses though fiber-optic lines leading down into an underground storage of solar panel modules.
Xcel Energy, which sells electricity and gas in eight western and mid-western states, says its SmartGridCity Project in Boulder, Colo. is now live. At least the smart distribution piece is up and running. That includes the network infrastructure and software for routing power to automated substations and around impacted power lines, and Xcel says the deployed technology is already enabling the company to anticipate network failures and fix broken gear before a major outage occurs. The milestone is important because it shows how quickly utilities are now moving to get smart grid projects deployed. The utility started construction on the project last year, and SmartGridCity is now one of the projects that is the farthest along in the U.S. and one of the first that can claim to have a distribution piece up and running.

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
