Sizing your HVAC System to go green and save energy

It's hot, the beads of sweat are rolling off your forehead in the kitchen. Time to replace that old air conditioning system with one of those green high efficiency units, right? Yes, but only after you make sure that your existing unit is sized properly using the what HVAC contractors call "Manual J." By using Manual J, you'll take going green a giant step further by basing your unit's size on good science and sound engineering, not on short cuts or what seems cool. We offer tips on how to ensure that your furnace or air conditioners are properly sized for your situation using Manual J and working with a HVAC contractor.

Wireless Electricity for Dreamers like me and you

in Energy, Going Green
Wireless Electricity in future homes

Any discussion of renewable energy involves how to get the power from remote areas to where it's needed. That involves building high voltage power lines across several States in many cases. It also involves years of effort, a great deal of environmental analysis and fighting every community that thinks the lines should be buried or go somewhere else.

Now I think of how great it would be if we could just send that electricity through the air just like we send things using wireless communications. Turns out that many people including Thomas Edison also thought it would be a cool idea. They too thought it was a bit absurd to drag all the cables across the country.

Solar Hybrid- Less smoke but plenty of mirrors here

Martin Next Generation Solar Energy Center

Later this year, Florida Power & Light Company will start operating its new concentrated solar power plant that has enough mirrors to cover 80 football fields on the shores of Lake Okeechobee in Florida. The mirrors will direct sunlight and produce steam to turn a turbine and generate electricity. The 75 megawatt plant will provide enough power for 11,000 homes.

University of Illinois Scientists' research yields more efficient Photovoltaic panels

Thin film solar

Despite the fact that silicon is the industry normal semiconductor in many electronic devices, which includes the pv cells that photo voltaic panels use to transform sunshine into energy, it is hardly the most efficient material on the market.

Cape Wind project approved after 9 years

Nysted Offshore Wind Farm in Denmark

Recently U.S. Secretary of the Interior Ken Salazar approved the Cape Wind Energy Project. Many people were excited about this.....and they should be. After all it took only 9 years to get this far. Sadly, this does not mean that the project will ever be built. Instead it may illustrate how broken our system for building energy infrastructure is.

Cheap Solar right around corner

Solar energy analyst say that a new age of cheap solar is upon us. By the year 2019, prices could decline by 60 percent from an average of $5.12 a watt to $2.11 per peak watt. That would mean widespread use of solar will prevail as prices decline.

Nebraska decides to become wind energy exporter

in Energy
Wind energy potential of various States

We' ve always maintained that the reak kingpins of wind energy are the various States in the Midwest that have good wind resources. Recently Nebraska Gov. Dave Heineman signed a bill that removes barriers to the state’s wind development, especially for facilities built to export electricity to other states.

Why the Change?
Turns out that energy companies wanted no part of wind energy in Nebraska. That was becasue the States's antiquated 1934 Public Power Law gave public power authorities the right of eminent domain, both to build transmission lines and to take over any generation facility with only “reasonable compensation.”  So if someone spent $500 million to build a wind energy farm, the State could come in and condemn the project and pay the owner only $400 million.

Shale gas could transform U.S. Economy

Despite all the excitement about the Smart Grid and renewable energy transforming the U.S. economy, the Obama Administration and Congress have made little progress. Health care has overshadowed energy concerns and the States have effectively blocked any new interstate power projects. Lucky for us, the natural gas industry has discovered and begun to extract enormous volumes of natural gas from shale formations located in five States. One energy executive predicted that we could fuel every car and light and heat every home in the country for more than 120 years.

There's a problem though. The natural gas industry will have to take concrete steps to address and control environmental problems caused by hydrofracking before shale gas drilling becomes the poster child of the NIMBY movement.

Google makes a splash in power markets and home energy monitoring

Chicago Mercantile Exchange

The Federal government recently granted Google the authority to trade power and to buy and sell wholesale power. With this new authority, Google hopes to reduce its electricy bills by trading directly with suppliers. The federal government will specifically allow a newly created subsidiary, Google Energy, to do everything that a traditional utulity does.

Reducing Your Personal Carbon footprint one step at a time

Carbon footprint

Many of us realize that if we are to make any progress in reducing our carbon footprint and energy use, it has to start at a personal level just like Ed Begely and Bill Nye did. It's really up to you and me to do something and certainly not the government or the politicians. The government is quite capable of getting it's own house in order. In fact, the Administration might take some cues from the three carbon calculators to determine their agency's carbon footprint and energy consumption and also two distinct paths to take to control them.
