  • 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

    (Information provided by DSIRE - Last reviewed 02/19/2009) The information below is somewhat dated, the incentives have been extended, but reduced.  See our more up to date article. Incentive Type:   Personal Tax Credit State:   Federal Eligible Renewable/Other Technologies:   Solar Water Heat, Photovoltaics, Wind, Fuel Cells, Geothermal Heat Pumps, Other Solar Electric Technologies Applicable Sectors:   Residential Amount:   26% Maximum Incentive:   Solar-electric systems Read More
  • 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!”

Native American solar advances

The Arizona Republic has a good article on residential solar on the Hopi and Navajo reservations in Arizona and New Mexico. Even after years of legislative push, large swaths of Native American localities still lack access to electricity. More than 15,000 Hopi and Navajo households live without electricity, according to officials.

Now, crowdsourced and community-level efforts are leading the way in providing reliable energy sources to native homes.

Biden releases ambitious plan for solar energy

By Ivan Penn | New York Times

The Biden administration on Wednesday released a plan to produce almost half of the nation’s electricity from the sun by 2050 as part of its effort to combat climate change.

Solar energy provided less than 4 percent of the country’s electricity last year, and the administration’s target of 45 percent would represent a huge leap and will most likely take a fundamental reshaping of the energy industry. In a new report, the Energy Department said the country needed to double the amount of solar energy installed every year over the next four years compared with last year. And then it will need to double annual installations again by 2030.

Here is What it Will Cost You to Achieve 100% Clean Energy -Intro

On August 12, 2021 the Office of Arizona Corporation Commission Chairwoman Lea Márquez Peterson released an interesting summary of the average future bill impact to residential customers  up to 2050, depending on the utility and the amount of emission reductions that each utility achieves within that time.  Worth a read.

PHOENIX - Several clean energy proposals are currently pending before the Arizona Corporation Commission. After several months, the Commission has received an independent analysis of at least two of these proposals: 100 percent zero-emission energy by 2050 and 80 percent clean energy by 2050.
