How to measure solar energy use in California’s state forests

California is the country’s biggest source of solar energy and its forests are the state’s most valuable asset, but the state also needs to cut greenhouse gas emissions and curb other pollutants, according to a report from the Center for Biological Diversity.

The report says California’s forests could become more expensive and vulnerable to fires and climate change if the state doesn’t address the issue.

The report, released Thursday, found that California’s total annual forest-energy production reached 523 gigawatts last year.

That is nearly 20 times the amount that power plants use.

In California, the number of trees fell by 9.2 million, and the average tree area fell by nearly half.

The state has about 1.3 million acres of forest, or 3.5 percent of the state.

But the report said the number could be even more if the number in the state is more sustainable.

The forests’ forests contain valuable nutrients and carbon that are key to human health, and they also have a significant role in maintaining water, food and energy production, said Matthew Kuczynski, director of the Center’s Beyond Carbon program.

The trees are also vital for maintaining ecosystems and the soil, which is essential for the production of crops, fish and trees, the report says.

The forests’ carbon footprint can be huge, the Center found, with nearly 1.5 million tons of carbon released each year.

It found that the carbon in a forest is equal to the carbon burned by a coal plant or oil and gas facility.

It’s the most significant carbon footprint of all of California’s natural resources.

The vast majority of that carbon is used for electricity generation, and in the future, many of the same carbon emissions will be used for new projects.

In the coming decades, the center estimates, the state will be importing more than 40 percent of its electricity from offshore wind and solar power.
