Head Start Towards 2020: California Reduces CO2 Emissions for Third Year in a Row

Comparison of California carbon emissions by sector from 2008-2011California’s CO2 emissions fell in 2011 for the third straight year, putting the state in a good position for meeting its target of reducing carbon emissions to 1990 levels by 2020, according to the California Air Resources Board (CARP) and as mandated by California AB32 (the Global Warming Solutions Act of 2006). Since businesses began reporting data in 2008, emissions have steadily declined from 133,4 million tons to 111million tons of carbon dioxide equivalent, shedding a full 22 percent in 2011.

Electricity production, once the leading sector for CO2 emissions in the state, made the biggest inroad towards reduction targets by cutting emissions 17.5 million ton between since 2008. Emissions from electricity generation was 34.9 million tons in 2011. Read More→

Wind Energy Production Hits New Record in California Last Week

Wind energy hits record peak in CaliforniaThe California Independent System Operator (Cal-ISO), the state’s grid operator, announced last Friday (Earth Day) that the state hit a record level of peak wind energy output last week of 2,432 megawatts, outpacing last year’s record of 1,915 MW. Peak refers to the amount of energy generation is available while demand is highest. Last week’s record peak comprised 5 percent of total demand.

The announcement came as part of Cal-ISO’s 2011 summer assignment. Due to what the report refers to as a “modest economic recovery,” summer peak demand is expected to increase 1.5 percent from last year’s 47,127 MW to 47,814MW.

The report credits the growth in wind energy generation to California’s Renewable Energy Portfolio Standard that mandates 33% total energy generation from renewables by 2020.

The state has approximately 7,300 MW of renewable energy currently online. After wind energy, geothermal is the primary source of renewable energy in California, followed by small hydro, biomass, solar, and biogas.

Most non-renewable energy generation (68 percent) comes from natural gas in California, with large hydro contributing 16 percent of total generation, and nuclear at 9 percent.
