Solar Hot Spots and Clean Energy Potential Pinpointed in New Maps

Renewable Energy

How will Los Angeles County prepare for a warmer future? And what role could clean energy investments play?

A joint project of Environmental Defense Fund (EDF) and UCLA Luskin Center for InnovationLos Angeles Solar and Efficiency Report (LASER)—provides new data designed to help the public and policymakers prepare for the effects of climate change, from current environmental health risks to estimated temperature increases and climate change vulnerability throughout the region. It can also be used by communities to help identify opportunities to invest in projects that will create renewable energy jobs and cut electricity bills.

Source: UCLA Luskin Center, “Los Angeles County

Solar Atlas” (2011). UCLA used and modified data from the Los Angeles County Chief Information Office, the
Los Angeles County Solar Map. http://solarmap.lacounty.gov. Disadvantaged communities are outlined in grey lines and identified per California Environmental Protection Agency and the Office of Environmental Health Hazard Assessment, “California Communities Environmental Health Screening Tool Version 2.0” (2014). http://oehha.ca.gov/ej/ces2.html.

“The project is timely because with new state funding sources becoming available, LASER can help inform how the region invests resources to address pressing environmental challenges while providing job opportunities in its most impacted communities,” said Colleen Callahan, lead author of the study and deputy director of the UCLA Luskin Center for Innovation.

The data-driven mapping tool, by parcel-level analysis, illustrates the area’s renewable energy potential through rooftop solar energy generation and energy efficiency measures. L.A. County presently has about 98 percent of its solar capacity untapped. The tool points out that if the county achieved only 10 percent of its rooftop solar potential, it would generate 47,000 jobs and cut almost 2.5 million tons of CO2 emissions each year.

The release today of the newest version of LASER is part of UCLA's "Thriving in a Hotter Los Angeles" project, which sets a goal for the region to use solely renewable energy and local water by 2050, and a response to President Obama’s Climate Data Initiative, which calls for leveraging public data to stimulate collaboration and innovation in support of national climate change preparedness.

LASER was highlighted in a White House announcement emphasizing ongoing efforts to broadly advance the initiative. “Through his Climate Data Initiative, President Obama is calling for all hands on deck to unleash data and technology in ways that will make businesses and communities more resilient to climate change,” said John P. Holdren, President Obama’s science advisor. “The commitments being announced today answer that call.”

Millions of solar panels clustered together to form an island could convert carbon dioxide in seawater into methanol, which can fuel airplanes and trucks, according to new research from Norway and Switzerland and published in the Proceedings of the National Academy of Sciences journal, PNAS, as NBC News reported. The floating islands could drastically reduce greenhouse gas emissions and dependence on fossil fuels.

More than 40 percent of insects could go extinct globally in the next few decades. So why did the U.S. Environmental Protection Agency (EPA) last week ok the 'emergency' use of the bee-killing pesticide sulfoxaflor on 13.9 million acres?

EcoWatch teamed up with Center for Biological Diversity via EcoWatch Live on Facebook to find out why. Environmental Health Director and Senior Attorney Lori Ann Burd explained how there is a loophole in the The Federal Insecticide, Fungicide, and Rodenticide Act under section 18, "that allows for entities and states to request emergency exemptions to spraying pesticides where they otherwise wouldn't be allowed to spray."
