It is time to start thinking about getting our homes ready for winter. Maintenance and repair work done while the weather is still mild will pay off not just in the coming cold weather, but with year round benefits. Here are five common issues to think about when considering your winterization projects, and how to avoid making some common mistakes while improving your house.

Known for building homes across the world for those in need, Habitat for Humanity now celebrates the occupancy of the program’s first LEED Silver certified homes in San Pedro, CA.

Begun during the 2007 Jimmy Carter Work Event over six days last year, 16 local families now enjoy the fruits of their labor - homes built alongside more than 5,000 volunteers. Not only are the homes LEED Silver, but they have another enviable feature: they include access to solar energy. Collectively, the families’ energy bills are expected to be reduced by $200,000 over time (keep an eye out for a related story about the innovative installation at CleanTechnica.)

In 2005, Governor Schwarzenegger signed into law Executive Order S-3-05 which sets a long term greenhouse gas emission reduction target of 80% below 1990 levels by 2050. Reaching this ambitious target will require that California embark on a comprehensive strategy to make aggressive reductions in greenhouse gas emissions over the next four decades.

Nationwide, electricity generation is is the second largest contributor to greenhouse gases. It is incomprehensible how the 80% greenhouse gas reduction target could be reached without tremendous amounts of renewable energy and energy efficiency. I am not saying that greenhouse gas reductions and renewable energy are the same but they certainly are not apples and oranges. I’d say they are more like oranges and tangelos. If we want significant greenhouse gas emissions, we’re going to need to ramp up renewable energy and quick.

If the U.S. moved aggressively to start harnessing the solar power it receives daily, it could generate enough clean energy to meet the country’s needs many times over, according to a new report from Environment Florida.

The report, “On the Rise; Solar Thermal Power and the Fight Against Global Warming,” touts the multiple benefits of solar thermal power that the U.S. has barely begun to tap. One, it’s a clean source of energy that could replace other power sources that generate greenhouse gases and worsen climate change. Two, by storing thermal energy, it can generate electricity even when the sun isn’t shining. And ,three, it’s wildly abundant in the U.S., offering way more clean energy than we currently use on a daily basis.

Cities can develop their own renewable energy and energy efficiency finance programs suited to their residential and commercial needs. For instance, in November 2007, the Berkeley City Council authorized staff to develop a plan to pay for the installation of solar panels and solar hot water systems for any homeowner or commercial building owner. Property owners retain ownership of the solar systems, paying back the cost over 20 years through an assessment on the annual property tax bill. This program entails little risk on the part of the city or the building owner, and overcomes a common obstacle of a costly up-front investment which may take more years to recoup savings than the owner intends to keep the building.

Once accepted into the program, a property owner would schedule an appointment for a solar installer to determine the appropriate solar system for the property. The city would pay the homeowner for the system and its installation, minus any applicable state and federal rebates, and would add a special tax to the property owner’s tax bill to pay for the system.

August 21, 2008 - State regulators in Colorado have given the green light to plans by Xcel Energy to shut down two coal-powered energy plants in the state, and build one of the world’s largest utility-scale solar-power facilities.

Following discussions lasting several days, the Colorado Public Utilities Commission (CPUC) backed the power company’s voluntary decision to close the two coal-fired plants at Denver and Grand Junction, making Xcel the first utility in the U.S. to make such a move solely in an effort to reduce emissions.

The prospects for renewable energy in Pennsylvania received a significant boost on July 9, when Democrat Governor Edward Rendell signed into law a Bill establishing a $650 million energy fund to support the sector.

The move follows an earlier commitment by Rendell to make the state a leader in pursuing energy independence, by creating jobs in the renewable energy sector and reducing dependence on foreign oil.

Speaking about the potentially far-reaching impact of the fund, Governor Rendell said:

“This new investment fund will strategically target new resources to leverage as much as $3.5 billion in private investment and create at least 13,000 new, good-paying jobs in an industry that is sure to be to the 21st century what information technology and biosciences were to the later 20th century.”

The Florida Public Service Commission has “unanimously and enthusiastically” approved a plan to build America’s largest commercial solar-power plant in the state. The committee also gave the green light to a further two facilities, due to go on-line in 2009.

Florida Power & Light have selected SunPower to construct the three solar-power plants in the center of the state. The largest, a 75-megawatt plant in Martin County on the East Coast, will be connected to a natural gas plant. Another 25-megawatt plant in DeSoto County will be the largest photovoltaic facility in the country, while a third, 10-megawatt photovoltaic facility is to be housed at the Kennedy Space Center.

Everyone knows we need green energy to fight global warming. But there’s another big reason to tap renewable power sources –- not enough water.

Large swaths of the Southwest and Southeast are in the throes of debilitating droughts. North Texas and Oklahoma’s recent dry spell dragged on from 2003 to the spring of 2007 (more on U.S. droughts). Droughts have even wiped out entire civilizations like the Anasazi (see Jared Diamond’s Collapse and Eugene Linden‘s Winds of Change).

But today’s water problems are far more profound than those of the Anasazi. The huge quantities we use — unprecedented in human history — make us more vulnerable to drought. Our water woes stem from an ever-increasing demand for water to slake the thirsts of a growing population on the one hand and to irrigate crops to feed that same population on the other.

Few people appreciate that yet another sector is clamoring for more water — the power industry. Fortunately we have the technology to wean this one from our dwindling supplies. (more…)

Orlando, Florida, recently became one of 12 cities across the U.S. chosen as a federal Department of Energy (DOE) “Solar America City.”

Each of the dozen cities will receive $200,000 to advance the use of solar technologies in their communities. All the cities were selected for “their commitment and comprehensive approach to the deployment of solar technologies and the development of sustainable solar infrastructures,” according to the DOE.
