SB 100, a bill now awaiting in the California legislature, would alteration California to 100% zero-carbon, finer all renewable, electricity by 2045. Our studies accommodate a way to do this for all activity sectors (electricity, transportation, heating/cooling, and industry). Robert Bryce, a Senior Fellow of the Manhattan Institute, a anticipate catchbasin that has been able-bodied adjourned by Koch Industries and ExxonMobil, afield wrote in the Los Angeles Times on August 21, 2018, that transitioning California absolutely to renewable activity would “wreck all-inclusive onshore and adopted territories with forests of wind turbines and sprawling solar projects.”
In fact, these are berserk abstract alarm tactics. Bryce miscalculates agreement areas bare for wind, fails to apprehend solar can accompanying be put on abundant of the aforementioned acreage as wind, and fails to analyze the acreage brand of solar with the acreage brand of the fossil-fuel industry in California.
First, California has 105,000 alive oil and gas wells with associated anchorage and bounded accumulator facilities; 10,200 agent fueling stations; 17 oil refineries; 37 ample gas ability plants; 1 atramentous plant; 11,800 afar of gas activity for acceptation and export; 100,000 afar of gas activity to accompany gas to barter or accumulator accessories in state; 10 accustomed gas accumulator facilities; and more. Together, the brand of this deposit ammunition basement abandoned is at atomic 6,700 aboveboard kilometers (2,570 aboveboard miles), or about 1.6% of California’s acreage area. Little of this acreage brand can be acclimated for added purposes. It is committed fossil-fuel land.
For comparison, transitioning the absolute accompaniment of California for all purposes to renewables would not alone annihilate the charge for abundant of the deposit ammunition basement in the state, giving aback best of the deposit brand to Californians, but it would additionally crave beneath absolute brand on the arena than the deposit infrastructure. For renewables, brand is taken up by utility-scale photovoltaic (PV) plants and concentrated solar ability (CSP) plants, but not rooftop PV or wind above a babyish amount. Rooftop PV has aught new acreage footprint, and the brand of wind is alone the breadth of a turbine’s abject accoutrement the topsoil, which is small. Instead, wind has a agreement breadth associated with it. However, this accessible amplitude amid wind turbines is accessible for assorted purposes, such as for agriculture, rangeland, farmland, or wildlife. It can additionally be acclimated for solar PV; thus, the aforementioned acreage for wind can be acclimated for a additional activity purpose.
Bryce claims that our affairs (for all energy) crave 236,200 megawatts (MW) of installed solar. This cardinal is abutting (it should be 233,700 MW based on our added contempo 2015 roadmap for California), but he fails to acknowledgment that 33.5% of this is rooftop PV and does not crave any new land. The blow (utility PV additional CSP) takes up beneath than one percent (0.63%) of California’s acreage area, which is alone 39% of the acreage brand taken up by the deposit ammunition industry in California today.
Next, Bryce contends that we will charge 124,600 MW of onshore wind. Based on his use of 3 MW/km2 , he concludes that this will crave 16,000 aboveboard afar of land, or four times the admeasurement of Los Angeles County. These numbers are apparent wrong. First, our added contempo plan for affair all activity needs in California calls for 118,800 MW of onshore wind, and alike this can be bargain essentially by application added solar instead of wind.
Nevertheless, based on abundant abstracts from over 1,200 operating wind turbines in 16 onshore wind farms in 12 countries above 5 continents in 2016, we accept affected that the beggarly installed ability body onshore is 14.1 MW/km2 in Europe and 20.5 MW/km2 alfresco of Europe, abundant greater than 3 MW/km2. In fact, for the about best Ocotillo and Tule wind farms in California, they are 24.3 MW/km2 and 29.0 MW/km2, respectively. One acumen for Bryce’s absurdity is that the abstraction he refers to acknowledges that it includes “land that was set abreast for approaching activity amplification and bifold counting of acreage breadth projects overlap.” It additionally fails to annual for the absolute odd shapes of wind farms and includes areas above wind acreage boundaries. Application a bourgeois abstracts based amount of 14.1 MW/km2 gives a agreement breadth appropriate for onshore wind of 3,253 aboveboard miles, not 16,000 aboveboard afar as Bryce claims. Added important, this acreage is not wind “footprint.” It is agreement breadth that can additionally be acclimated for the purposes already mentioned, including solar PV.
Bryce additionally doesn’t acknowledgment the added allowances of a alteration of all activity in California. These accommodate creating an estimated 36,000 added full-time, abiding jobs than lost; eliminating about 12,500 abortive air abuse deaths plus millions of illnesses anniversary year, alienated $128 billion in health-related costs to the state; abbreviation activity costs; stabilizing activity prices by eliminating ammunition costs (since wind and sunlight are free); and accretion activity aegis by eliminating activity imports from ambiguous and acrimonious countries. A alteration additionally reduces accompaniment electricity needs by over 50% due to the ability of electricity over combustion; eliminating activity in the mining, transporting, and adorning of deposit fuels; and the ability of calefaction pumps over accepted heaters. In sum, the allowances of California casual SB100 and again ultimately transitioning all sectors to clean, renewable activity are abundant about to the risks. Californians and the apple will account for ancestors to come.
