  • Renewable Tracking Progress Appendix
    California Energy Commission – Tracking Progress Renewable Energy Advancing the use and availability of renewable energy is critical to achieving California’s ambitious climate goals. With this in mind, California has pursued a suite of policies and programs aimed at advancing renewable energy and ensuring all Californians, including low- income and disadvantaged communities, benefit from this transition. This report presents the state’s progress in meeting its renewable energy goals and provides an updated analysis through 2018 of renewable energy generation, installed renewable capacity, and a discussion of the trends, opportunities, and challenges associated with the renewable energy transition. More detailed figures and tables are included in the appendix.1 Renewable Energy Serving California Consumers Annual Renewable Percentage: Renewables Portfolio Standard Progress An increasing percentage of energy consumed by Californians comes from renewable sources. A key mandate advancing the use of renewable energy has been the Renewables Portfolio Standard (RPS), which requires California load-serving entities2 (LSEs) to increase their procurement of eligible renewable energy resources (solar, wind, geothermal, biomass, and small hydroelectric) to 33 percent of retail sales by 2020 and 60 percent of retail sales by 2030. Based on reported electric generation from RPS-eligible sources divided by forecasted electricity retail sales for 2019, the California Energy Commission (CEC) estimates that 36 percent of California’s 2019 retail electricity sales was served by RPS-eligible renewable resources as shown in Figure 1. Although this number is not a final RPS determination, it is an important indicator of progress in achieving California’s RPS goals. Figure 1: Estimated Current Renewables Portfolio Standard Progress Source: CEC staff analysis, December 2019 The annual renewable percentage estimated by the CEC has continued to increase in recent years, often ahead of the timelines envisioned by prior legislation.

  • Wind Energy Is Not the Answer
    WIND ENERGY IS NOT THE ANSWER by Bradley S. Tupii Abstract. Wind energy is not the answer to climate change concerns and cannot do the heavy lifting required by the modern American economy. It would take hundreds of thousands of wind turbines to make a substantial contribution to America’s energy needs. Building so many turbines inevitably causes conflicts with human and animal habitats. Wind turbine noise is a serious problem for those who live in the vicinity of so-called wind farms. * * * Introduction. Wind energy is not a modern phenomenon. Man harnessed the wind with sailboats and windmills hundreds of years ago. Charles Brush developed a wind-powered electric generator in 1888.2 Small, wind-powered generators such as the Jacobs Wind-Electric Machine became popular in the Midwest in the early 20th Century.3 These windmills became obsolete when Depression-era programs brought more reliable electric power to rural areas.4 Wind energy began a slow resurgence during the Carter administration when the Public Utility Regulatory Policies Act of 19785 fostered state tax incentives for wind power development and allowed non-utility energy producers to sell electricity to utilities.6 Currently, wind power is hailed by some as a key weapon in the battle against global warming and as an important contributor to American energy independence. This paper will argue that wind energy is neither. Wind power cannot generate enough reliable electricity to replace conventional energy sources, including those that generate greenhouse gases. Assuming for the sake of argument that carbon dioxide is contributing to global climate change, wind power will not materially reduce CO2 emissions.

    April 23, 2018 Mary Nichols, Chair California Air Resources Board 1001 I Street Sacramento, CA 95814 Subject: Comments to the Proposed 2018 Amendments to the Low Carbon Fuel Standard Chair Nichols and Members of the Air Resources Board: I am writing on behalf of Tesla to provide recommendations to the California Air Resources Board (CARB) as a part of the stakeholder comment process for the 2018 Amendments to the Low Carbon Fuel Standard (LCFS). The LCFS regulation is an important tool to reduce carbon emissions in the state’s transportation sector and to promote sustainable technology deployment. Within the LCFS, the electricity pathway has great potential to dramatically impact the adoption of Electric Vehicles (EVs) and encourage the use of solar energy. To realize this potential, we recommend CARB consider several modifications to the regulation in this rulemaking. Tesla has five key recommendations for CARB to consider in this rulemaking: 1. Data-Backed Credit Generation: permit EV manufacturers to utilize fleet-wide, aggregated charging data from vehicle telematics to earn additional residential LCFS credits if real-world charging exceeds CARB’s estimated charging for the manufacturer’s fleet. 2. Use of Residential Charging Funds: allow EV manufacturers to opt in and earn base residential charging credits in lieu of utilities for their fleets, as automakers are best- positioned to utilize this value to administer consumer-facing incentives to accelerate zero-emission vehicle deployment in the state. 3. Renewable Energy Matching: approve staff’s proposal, with modifications, to allow book-and-claim accounting for renewable electricity supplied as a transportation fuel and allow automakers to generate these credits by matching solar production data with fleet-wide, aggregated charging data from vehicle telematics.

  • Modeling the Future California Electricity Grid and Renewable Energy Integration with Electric Vehicles
    energies Article Modeling the Future California Electricity Grid and Renewable Energy Integration with Electric Vehicles Florian van Triel 1,2,3,* and Timothy E. Lipman 2 1 Department of Vehicle Mechatronics, Technical University of Dresden, 01069 Dresden, Germany 2 Transportation Sustainability Research Center, University of California-Berkeley, Berkeley, CA 94704, USA; [email protected] 3 BMW AG, Petuelring 130, 80788 Munich, Germany * Correspondence: [email protected] Received: 22 July 2020; Accepted: 30 September 2020; Published: 12 October 2020 Abstract: This study focuses on determining the impacts and potential value of unmanaged and managed uni-directional and bi-directional charging of plug-in electric vehicles (PEVs) to integrate intermittent renewable resources in California in the year 2030. The research methodology incorporates the utilization of multiple simulation tools including V2G-SIM, SWITCH, and GridSim. SWITCH is used to predict a cost-effective generation portfolio to meet the renewable electricity goals of 60% in California by 2030. PEV charging demand is predicted by incorporating mobility behavior studies and assumptions charging infrastructure and vehicle technology improvements. Finally, the production cost model GridSim is used to quantify the impacts of managed and unmanaged vehicle-charging demand to electricity grid operations. The temporal optimization of charging sessions shows that PEVs can mitigate renewable oversupply and ramping needs substantially. The results show that 3.3 million PEVs can mitigate over-generation by ~4 terawatt hours in California—potentially saving the state up to about USD 20 billion of capital investment costs in stationary storage technologies.
