  • New Discovery Could Improve Organic Solar Cell Performance

    While there is a growing market for organic solar cells ­­– they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels – they also tend to be less efficient in converting sunlight to electricity than conventional solar cells. Now, scientists who are members of the Center for Computational Study of Excited-State Phenomena in Energy Materials (C2SEPEM) a new Read More
  • Know Your Rights

    Arizona law protects individual homeowners’ private property rights to solar access by dissolving any local covenant, restriction or condition attached to a property deed that restricts the use of solar energy. This law sustained a legal challenge in 2000. A Maricopa County Superior Court judge ruled in favor of homeowners in a lawsuit filed by their homeowners association seeking to force the homeowners to remove Read More
  • Home Battery Systems

    Rooftop solar panels are common in Arizona thanks to abundant sunshine, but to get even more use from the technology, homeowners are beginning to pair them with large home batteries. Batteries allow homeowners to store their surplus electricity, rather than send it to the grid in exchange for credit from their electric company. Read More
  • Solar Hot Water

    There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't. The typical solar water heater is comprised of solar collectors and a well-insulated storage tank. The solar collector is a network of pipes that gathers the sun's energy, transforms its radiation into heat, and then transfers that heat to either water or a heat-transfer fluid. Read More
  • Federal Residential Renewable Energy Tax Credit

  • Solar Building Design in Arizona

    The idea of using the sun to meet the energy needs in our buildings has been with us since the time of the Greeks, with some of the design manifestations even evident in the prehistoric structures of Arizona and the Southwest. There is a great historic tradition for Arizona buildings that utilize our most abundant resource, and the current increases in The idea of using Read More
  • How Not to- Battery Connections

    Photo shows the situation after a battery discharge test at 300 amps was terminated on a 1530 AH IBE battery string when one post melted. During the discharge test all cell voltages are logged. The sum of the cell voltages was 2.73 volts lower than the 48-volt string voltage. This is an average of 118 mv per inter-cell connection, 5-10 mv is the normal range Read More

What’s Really Green and What’s Really New

Ask Americans what the Green New Deal is all about, and you’ll get two basic answers. Most often you’ll hear, “It’s about moving to renewable energy in order to fight climate change.” You’ll also hear, from a camp further right, “It’s all about socialism!”

Biden administration announces goal of 5 million homes

The Department of Energy on November 5, 2021 announced a target of the equivalent of five million homes powered by community solar energy by 2025.

The target would save $1 billion and contribute to administration goals of fully renewable electricity by 2035, according to the department.

“Community solar is one of the most powerful tools we have to provide affordable solar energy to all American households, regardless of whether they own a home or have a roof suitable for solar panels,” Energy Secretary Jennifer M. Granholm said in a statement. “Achieving these ambitious targets will lead to meaningful energy cost savings, create jobs in these communities, and make our clean energy transition more equitable.”

The Build Back Better plan for renewables-2021

On OCTOBER 28, 2021 President Biden Announced the Build Back Better Framework. This will have a major impact on Renewable Energy and sustainability. Some of the major components are:

  • The largest effort to combat climate change in American history. The framework will cut greenhouse gas pollution by well over one gigaton in 2030, reduce consumer energy costs, give our kids cleaner air and water, create hundreds of thousands of high-quality jobs, and advance environmental justice by investing in a 21st century clean energy economy – from buildings, transportation, industry, electricity, and agriculture to climate smart practices across our lands and waters.

 

  • Ensure clean energy technology – from wind turbine blades to solar panels to electric cars – will be built in the United States with American made steel and other materials, creating hundreds of thousands of good jobs here at home. The Build Back Better legislation will target incentives to grow domestic supply chains in solar, wind, and other critical industries in communities on the frontlines of the energy transition. In addition, the framework will boost the competitiveness of existing industries, like steel, cement, and aluminum, through grants, loans, tax credits, and procurement to drive capital investment in the decarbonization and revitalization of American manufacturing.

 

  • Advance environmental justice through a new Clean Energy and Sustainability Accelerator that will invest in projects around the country, while delivering 40% of the benefits of investment to disadvantaged communities, as part of the President’s Justice40 initiative. The framework will also fund port electrification; facilitate the deployment of cleaner transit, buses, and trucks; and support critical community capacity building, including grants to environmental justice communities. In addition, the framework will create a new Civilian Climate Corps – with over 300,000 members that look like America. This diverse new workforce will conserve our public lands, bolster community resilience, and address the changing climate, all while putting good-paying union jobs within reach for more Americans.

Scottsdale Proposes Adoption of new Energy and Green Construction Code

In alignment with Scottsdale’s overall building code updates, the city is preparing to adopt the 2021 edition of the International Green Construction Code (IECC) and the International Green Construction Code (IgCC). These updated codes will replace the currently adopted 2015 editions.

The IECC addresses residential and commercial energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment. Key changes to the 2021 IECC improve efficiency by 11.1 percent and reduce greenhouse gases by 10.7 percent over the 2015 IECC. These changes include new provisions that increase efficiency and encourage greater flexibility in design and construction. Amendments include electric vehicle charging infrastructure for new homes, apartments and hotels to support future EV charging demand. The IgCC is applicable to new commercial buildings and contains measures to help mitigate heat island effect, reduce water waste, mitigate greenhouse gas emissions, support renewables, improve indoor environmental health and lower the impact on natural resources.

The updated codes are planned to be presented to City Council for adoption in the first quarter of next year. The IECC and IgCC have already received support from the Scottsdale Environmental Advisory Council and is currently being reviewed by the Building Advisory Board.
