The use of sun control and shading devices is an important aspect of much energy-efficient building design.

Shading devices can have a dramatic impact on building appearance.

The energy a building requires can be divided into two basic categories.

First, the energy needed so that a building can be used, to create a comfortable climate.

This means the production and control of heat, cold, light and air.

Second, the additional energy required, dependant on the use of the building such as to power computers and secondary equipment in office and administrative buildings, or for production machines on the factory floor.

Appropriate sun shading systems can significantly reduce the energy required to provide heating, cooling and light.

Control intense direct sunlight will ensure a comfortable workspace.

This is critical for occupant visual and thermal comfort and for minimizing mechanical cooling loads.

In sunny weather, solar heat gains through glazing can represent…

See on Scoop.it – Green Energy Technologies & Development

Today, a new breed of CHP gen set ranging from micro- to large-scale multi-megawatt power sources is emerging. Most are transportable or built into shippingcontainers. Unlike solar and wind generators, their systems can make a lot more power with less real estate and run 24 hours a day, seven days a week every day of the year

 

Duane Tilden‘s insight:

There are some new generating systems running on biomass wood chips or pellets although they are not as popular as the defacto standard — natural gas powered sets. The fuels from biogas components can be reclaimed from farm products and landfills, proving economical by using the methane gas created from food product waste.

Soon, investors will be able to learn more about companies in the same space where they play Candy Crush Saga. The Securities and Exchange Commission declared Tuesday that companies can notify their investors of news through Facebook and Twitter.

Duane Tilden‘s insight:

George Canellos, acting director of the SEC’s division of enforcement, commented on this new development in a press release:

One set of shareholders should not be able to get a jump on other shareholders just because the company is selectively disclosing important information. Most social media are perfectly suitable methods for communicating with investors, but not if the access is restricted or if investors don’t know that’s where they need to turn to get the latest news.

What brought about this decision was a post on the …

ComEd submitted this week to the Illinois Commerce Commission data showing that the 2011 Smart Grid law created more than 2400 full-time equivalent jobs in Illinois in 2012.

Duane Tilden‘s insight:

“The grid modernization programs are putting many linemen, electricians and specialists who work on our electric grid back to work in well-paying, skilled jobs. This helps the Illinois economy and boosts other local industries, too,” said Michael Carrigan, president, Illinois AFL-CIO. “Getting the programs back on track will protect and increase jobs for Illinois workers.”

ComEd’s grid modernization investments have provided an important boost to Illinois manufacturers, suppliers and service providers with the expertise necessary to support the electrical system upgrade. Last year, ComEd awarded grid modernization contracts worth a total of $118 million, including 71 percent to Illinois companies providing services and products from engineering to cable to smart switches. Of the total, $54 million, or 46 percent, was spent with diverse suppliers.

The UK Top 100 firm [Ward Hadaway] has advised renewable energy company JFS & Associates on the latest in its series of joint ventures with farmers to install and build anaerobic digestion (AD) plants to generate green energy.

Duane Tilden‘s insight:

The plant being built at Howla Hay Farm will be capable of generating 250kWh of electricity enough to power 250 homes.

Matthew Flint, director at JFS & Associates, which is based in Stokesley, North Yorkshire, said: “It is great news to be able to announce the second in what we aim to be a whole series of these developments which provide a win-win for both parties in the joint venture.

“The farmer gets to share in the proceeds of the electricity generated opening up a new revenue stream as well as getting the benefit of the by-products of the process, such as heat and bio-fertiliser to further improve the profitability of their existing business.

“We get a readily available source of feedstock for the AD plants and, by using our expertise and experience in the renewable energy sector, we can generate and sell electricity to feed back into the National Grid.”

See on Scoop.it – Green Energy Technologies & Development

SolarReserve, a U.S. developer of large-scale solar power projects, today announced completion of the assembly of the molten salt receiver panels that sits on top of the 540 foot solar power tower for its 110 megawatt (MW) Crescent Dunes Solar…

Duane Tilden‘s insight:

The project will utilize technology […] to capture and store the sun’s energy in order to deliver a firm electricity supply to Nevada, day or night, without the need to burn fossil fuels. The molten salt “receiver” is actually comprised of panels formed by hundreds of special alloy tubes which will be flowing with molten salt for energy absorption and storage. Once complete, the project will be capable of storing 10 hours of full load electricity production, enough to power 75,000 homes at peak electric demand periods, even after dark.

The project closed financing and initiated construction in September of 2011 and is scheduled to complete construction and start plant commissioning at the end of 2013, including first electricity production by the end of the year. The Crescent Dunes project has secured a 25-year power purchase agreement with NV Energy to sell 100 percent of the electricity output of the facility to serve homes across Nevada.  […]

“The energy storage capability of this technology solves the problem of intermittency typical of other renewable energy sources. Additionally, because of it high efficiency, this technology can generate almost twice as much energy as a comparably sized solar facility, including facilities powered by photovoltaic panels or by a direct steam tower.” said Kevin Smith, CEO of SolarReserve.

Wind and Neodymium

Jack Lifton’s research on mineral resources make him an important figure in projecting the future of energy. Lifton spotted the Lemhi Pass thorium reserve discoveries early on, Lifton has recently focused on world rare earth production, and as Lifton has pointed out, rare earths will play important roles in the future of energy. Lifton pointed out the importance of the rare earth element neodymium for the wind generation industry.

There’s another rare earth metal that’s critically important to our society—neodymium. In 1984, General Motors and Sumitomo developed the neodymium iron boron alloy for permanent magnets, which is the basis of all modern electric motors because it allows you to make a very small electric motor with the highest possible power density. Neodymium total world production is less than 20,000 tons. That may sound like a lot to you, but it’s tiny. And the fact is it’s recently been projected that a single wind turbine electric generator producing 1 megawatt of electricity requires one ton of neodymium.

The liquid fluoride thorium reactor (acronym LFTR; spoken as lifter) is a thermal breeder reactor that uses the thorium fuel cycle in a fluoride-based molten (liquid) salt fuel to achieve high operating temperatures at atmospheric pressure.

The LFTR is a type of thorium molten salt reactor (TMSR). […]

In a LFTR, thorium and uranium-233 are dissolved in carrier salts, forming a liquid fuel. Typical operation sees the liquid fuel salt being pumped between a critical core and an external heat exchanger, where the heat is transferred to a nonradioactive secondary salt, that then transfers its heat again to a steam turbine or closed-cycle gas turbine.[2]

This technology was first investigated at the Oak Ridge National Laboratory Molten-Salt Reactor Experiment in the 1960s. It has recently been the subject of a renewed interest worldwide.[3] Japan, China, the UK, as well as private US, Czech and Australian companies have expressed intent to develop and commercialize the technology.
