Las Vegas has made huge strides in conservation efforts

Yes I know there are many things that are wrong about Las Vegas. People shouldn’t even be there in the first place. The rape of the river that no longer reaches the sea. The rape of the pristine desert and the death of many Native Americans. I lived there for a year and there is also the cheesy nature of the culture. But when they do something right, you got to give them credit.

Nevada Energy Star Partners Demonstrate Peak Performance (Web Only)

September 01, 2012

Las Vegas may appear balmy and inviting with its sparkling pools and swaying palm trees, but those who live in Neon City know the truth: It’s too cold in the winter and too hot in the summer.

Unfortunately, hundreds of thousands of homes that were built during an amazing 50 years of rapid growth in the Southwest do not incorporate modern advances in energy performance to accommodate the wild swings of desert climate. As temperatures climb to 110°F in the summer, many homes leak large amounts of cooled air through gaps in ducts, roofs, windows, and doors. And when the frigid north wind drops the temperature below freezing in the winter, heated air escapes, leaving living rooms and bedrooms uncomfortably cold and drafty. While Las Vegans know their climate, they may not realize that they are paying to heat and cool the great outdoors.

The dramatic temperature shifts in the high-desert climate make Las Vegas an ideal place for homeowners who are looking to make their homes more comfortable and to save substantially on their energy bills. Funded in part by DOE’s Building America program, the Building America Retrofit Alliance is working with the Nevada ENERGY STAR Partners–Green Alliance (NESP–Green Alliance), and with Better Building Performance, a Las Vegas company, to upgrade two typical homes top to bottom. Their goal has been to show homeowners and remodelers how easy and effective energy performance upgrades can be.

I normally would not think of Colorado as a solar state

But I imagine the whole “front range” of the rocky mountains is. Usually you think of deserts but really sunshine falls everywhere and the higher you go the more intensity it generates. So we close the week with this:

Colorado Solar Power

Despite Colorado’s fame as a skiing destination, Denver actually ranks 30th of 174 major U.S. cities in terms of sunshine potential, not far behind Honolulu and Miami. In fact, Colorado has the third highest installed solar PV generation capacity of any U.S. state (source: IREC US Solar Market Trends 2009). As a result of innovative policies and greater awareness of environmental issues, Colorado was an early adopter of solar energy systems. As of the end of 2009, the state had 59 megawatts of installed solar PV capacity, third highest among U.S. states despite the fact that the state ranks 22nd in terms of population. In addition, Colorado installed 53.6 megawatts of solar power in 2010, ranking Colorado fourth in the nation, which was double the output for 2009 (23.4 megawatts). Home to natural gas, oil and some of our nation’s best solar rebates, Colorado plays an important role in the United States’ energy industry. Colorado was the first state to create a Renewable Portfolio Standard (RPS), through a 2004 ballot initiative. Originally, the RPS mandated that all utilities with more than 40,000 customers provide at least 10% of their electricity from a renewable energy source. Through additional improvements, it is now mandated that by 2020 investor-owned utilities must provide 30% and cooperatives and municipal utilities with over 40,000 must provide 10% of their retail load from renewable energy sources. Investor-owned utilities also have a distributed generation requirement, which is good news for solar owners. By 2020, 3% of the retail load must come from customer solar electric systems, rather than huge solar farms. This means that investor-owned utilities will continue to offer fantastic solar incentives to consumers to increase the number of residential and commercial solar systems

I hate to say it but it couldn’t happen to a nicer company. For years they have been one of the least tolerant of companies. They resisted any thought of innovation. Stuck to burning coal and nuclear power plants long after it was fashionable. And snickered all the time like an evil teenager. They fought regulation until they were overwhelmed. Bad karma always comes to a bad end.

ComEd rate-hike issue delayed; customers keep switching

BY SANDRA GUY Business Reporter sguy@suntimes.com September 19, 2012 6:06PM

The Illinois Commerce Commission on Wednesday delayed until Oct. 3 reconsidering a Commonwealth Edison rate-hike request centered on how ComEd accounts for its pension assets.

he ICC previously approved a rate that ComEd claimed was inadequate, ruling that ComEd can’t earn a rate of return on a pension asset that isn’t fully funded.

The commission took up other issues at its meeting Wednesday in Springfield, and didn’t give a reason for the delay.

ComEd had proposed a decrease in its electricity rates totaling $40 million to $50 million, but because of the pension issue, the ICC decided May 29 to cut customers’ rates by four times that for a total of $168.6 million.

SF public power plan given tentative OK

John Coté
Updated 10:41 p.m., Tuesday, September 18, 2012
San Francisco took a major step toward public power Tuesday when the Board of Supervisors gave initial approval to a five-year contract with Shell Energy North America to provide 100 percent renewable power to San Franciscans willing to pay a premium.

The 8-3 vote provided a veto-proof majority for a program that will effectively break Pacific Gas and Electric Co.’s decades-old monopoly on the consumer power market in its headquarter city. It also lays the groundwork for city-owned renewable power production.

“The long-term goal is to really do our own generation,” said Ed Harrington, the outgoing general manager of the San Francisco Public Utilities Commission, who delayed his retirement to see the proposal brought before legislators.

The plan comes eight years after the city began setting up a community choice aggregation program, which allows municipalities to choose alternative electricity providers. Former Supervisor Tom Ammiano, now an assemblyman, began pushing for public power, a touchstone issue for many on the city’s political left, 14 years ago.

Coastal Windpower – Where the jobs are

Posted on by

This is pretty mundane from my perspective. The US is building 100s of wind farms around the country. The coasts are places where the wind is most powerful and consistent. Are the numbers accurate? Who knows? They likely would be higher than what is stated, so why worry about that?

http://thinkprogress.org/climate/2012/09/17/858551/offshore-wind-on-the-atlantic-cost-could-create-300000-jobs-and-200-billion-in-economic-activity/?mobile=nc

Offshore Wind On The Atlantic Cost Could Create 300,000 Jobs And $200 Billion In Economic Activity

By Climate Guest Blogger on Sep 17, 2012 at 3:12 pm

by Silvio Marcacci, via CleanTechnica

America has some of the best offshore wind resources in the world — especially along the Atlantic coastline. But while the promise is massive, zero turbines are currently spinning in U.S. waters.

Fortunately, federal and state governments have made significant progress toward the first offshore turbines and have put America at a turning point toward harnessing the more than 1,300 gigawatts (GW) of energy generation potential identified along our coasts. Harnessing a realistic fraction of offshore wind’s potential — 52GW — could power 14 million homes with clean electrons while creating over 300,000 new jobs and $200 billion in new economic activity in some of our biggest cities.

These findings come from “The Turning Point for Atlantic Offshore Wind Energy,” a new report from the National Wildlife Foundation (NWF) outlining the energy and economic benefits offshore wind could create in the U.S., highlighting progress made to date, and detailing policy action needed to realize the industry’s potential.

Federal Policy + State Action = Turbines

While it seems like offshore wind has been touted for years, the future is closer to reality than ever before.

Community Power in Lewes
Posted on September 10, 2012

Ouse Valley Energy Supply Company, or Ovesco as it is commonly known, is a powerful inspiration for enthusiasts of community renewable energy. In August I was given a guided tour of Ovesco projects by Chris Rowland, which you can see here, and then filmed Chris explaining the origins of Ovesco and outlining some of their projects. You can view the second film here.

Standing on a hill above Lewes you can not only see the solar PV installations completed by Ovesco but also arrays of panels inspired by their projects. The local football club, the leisure centre and many local homes, have all followed the example of Ovesco. Other sites are looking to follow and there are also plans for community wind and hydro-electric schemes.

The Ovesco website is a rich source of information and links for community renewable energy projects and is well worth a visit.

Below is an edited version of an article on the OVESCO website.

Power to the people of Lewes

How to Organize, Finance, and Launch Local Energy Projects

Is it possible to “relocalize” energy? This is a critical question that must be addressed if we are to achieve true global resilience.

In our brand new book (September 4, 2012), Power From the People, energy expert Greg Pahl decisively argues that the answer is YES.

Power From the People is the second book in our Community Resilience Guides series, The book illustrates how communities across the country are already generating their own energy at the local level. From citizen-owned wind turbines to co-op biofuel producers to community-wide initiatives combining multiple resources and technologies, Pahl outlines the steps necessary and plan, organize, finance and launch community energy projects.

The book showcases over 25 real-life examples of local energy projects, offering a range of challenges and solutions that can be adapted and reapplied.

The Drought And Power Plants – Unannounced production cuts

Posted on by

While I wrote about the higher output temperatures of power plant effluent (water) and the effects on the wild life and the surrounding environment. But the fact is, they have been dropping in production too. I mean if you can’t cool them, they will melt and for the most part that is a bad thing especially for the nukes. The President of PG&E was crowing about their nuke being cooled by sea water so “as to be not effected” by the drought and climate warming. He may want to rethink that.

Extreme Heat, Drought Show Vulnerability of Nuclear Power Plants

Reactor shutdown in Connecticut is latest sign that nuclear energy would face challenges from climate change.

Aug 15, 2012

Will 2012 go down as the year that left the idea of nuclear energy expansion in the hot, dry dust?

Nuclear energy might be an important weapon in the battle against climate change, some scientists have argued, because it doesn’t emit greenhouse gases. But separate of all the other issues with nuclear, that big plus would be moot if the plants couldn’t operate, or became too inefficient, because of global warming.

In June, InsideClimate News reported on the findings of Dennis Lettenmaier, a researcher at the University of Washington. His study found that nuclear and other power plants will see a 4 to 16 percent drop in production between 2031 and 2060 due to climate change-induced drought and heat.

Recycling By Anyother Name – Moves us to a steady state economy

Methane is the single biggest greenhouse gas that never gets talked about because environmentalists see it as a “bridge” to a clean energy future. Making power from food refuse makes complete sense. I hate to say it but backyard composters, as well meaning as they are, just throw the stuff up in the air.  Ashley Halligan sent me this article:

Resource Recovery Facilities: An Economic And Efficient Energy Supply

by Ashley HalliganProperty Management Analyst, Software Advice
July 12, 2012

Although the number of U.S. landfills has steadily declined since 1990, the size of landfills has increased. In fact, Americans generated 250 million tons of municipal solid waste (MSW) in 2010 alone. It’s thus no surprise that MSW landfills are our third-largest, human-generated source of methane emissions. But this is more an opportunity than it is a problem.

Many landfills are becoming resource recovery facilities–places where waste or byproducts are reclaimed and converted into energy. Captured by wells installed throughout a landfill, naturally-occurring methane emissions (or landfill gas–LFG) can be converted into multiple energy sources, including electricity, a replacement for fossil fuels in industrial operations, or upgraded to pipeline-quality gas. Methane’s heat can also be used directly. Of the approximately 2,400 operating or recently closed MSW landfills in the U.S., 535 (around 22 percent) currently have resource recovery projects.

To learn more about these projects and the benefits they deliver, I spoke to several industry experts–including David Specca, Assistant Director for Bioenergy and Controlled Environment Agriculture at the Rutgers University EcoComplex, and Barry Edwards, Director of Engineering and Utilities at Catawba County–and looked at three examples of successful projects.

Solar And Coal – You would not think they go together

Posted on by

I say this is a stretch. It is just the coal companies to throw a little sop to what “green” means. You judge for yourself.

Hybrid Solar Coal Plant Being Tested In Colorado

by

As much as we all want coal as an energy source to go away completely, we also know it will take the government and private sector sometime (too long in our opinion) to fully move to clean energy sources. In the meanwhile, methods need to be developed which can minimize the impact of fossil fuel usage on the environment. One such pilot project is going on near Grand Junction, Colorado, at Xcel Energy’s Cameo Generating Station using a unique solar-coal hybrid design.

Xcel Energy said it has connected a parabolic-trough solar technology system developed by Abengoa Solar to its coal power plant. This system concentrates solar energy to provide heat for producing supplemental steam for electric power production, which Xcel Energy feels will help lower the usage of coal as an energy source at this facility while also testing the commercial viability of concentrating solar power thermal integration and lowering carbon dioxide emissions.

This project is believed to be the world’s first known demonstration of the hybrid solar-coal approach using the parabolic-trough solar approach. It is part of a larger program by Xcel Energy to test promising new technologies with potential to lower greenhouse gas emissions and result in other environmental improvements. The company said this program allows it the opportunity to test these technologies and evaluate their cost, reliability and environmental performance at a demonstration scale before determining whether they should be deployed more widely
