100% Renewable Energy Transition unites solar, wind, hydropower, geothermal, and bioenergy with storage, smart grids, and sector coupling, delivering decarbonization, energy security, and lower LCOE amid post-Fukushima policy shifts and climate resilience goals.

Key Points

It is a pathway using all renewables plus storage and grids to fully decarbonize power, heat, transport, and industry.

✅ Integrates solar, wind, hydro, geothermal, and bioenergy

✅ Uses storage, smart grids, and sector coupling for reliability

✅ Requires enabling policies, finance, and rapid deployment

Renewable energy organizations representing different spheres of the renewable energy community have gathered on the occasion of the tenth anniversary of the Great East Japan Earthquake and Fukushima nuclear accident to emphasize that renewable energies are not only available in abundance, with global renewable power on course to shatter more records, but ready to deliver a renewable world.

The combination of all renewable technologies, be it bioenergy, geothermal energy, hydropower, ocean energy, solar energy or wind power, in particular in combination with storage options, can satisfy all energy needs of mankind, be it for power, heating/cooling, transportation, or industrial processes.

Renewables have seen tremendous growth rates and cost reduction over the past two decades, but there are still many barriers that need to be addressed for a faster renewable energy deployment to eventually achieve global 100% renewable energy, as outlined in an on the road to 100% renewables initiative that charts the path. It is up to political decision-makers to create the legislative and regulatory conditions so that the renewable energy community can act as fast as needed.

Such rapid switch towards renewables is not only a must in light of nuclear risks and the growing threats of climate change, but also the necessary response to the current pandemic situation. And it will allow those hundreds of millions of humans in unserved areas to get for the first time ever access to modern energy services, as noted by a new IRENA report that details how renewables can decarbonise the energy sector and improve lives.

Speakers from the renewable energy community presented today in a joint webinar that a renewable future is a realistic vision, representing:

Energy Watch Group, Global100RE Platform, Global100RE Strategy Group, International Geothermal Association, ISEP Japan, REN Alliance, World Bioenergy Association, World Wind Energy Association.

Dr. Tetsunari Iida, Director of the Institute for Sustainable Energy Policies ISEP Japan:

Ten years ago, on 11 March 2021, the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant accident occurred. It is a "coincidence of global history" that it now coincides with the starting point of the 100% renewable energy initiative that is accelerating around the world.

The world has changed dramatically since 311. Germany, Italy, Switzerland, Taiwan, South Korea, China and many other countries were all shocked by 311 and shifted their focus from nuclear power to renewable energy, and in the U.S. clean energy industries are setting sights on market majority to accelerate this trend. The next ten years will be the decade in which this perception will rapidly become the "new reality". 311 was the "starting point" for a structural energy shift in world history.

Hans-Josef Fell, former MP, President of the Energy Watch Group and co-initiator of the Global100RE Strategy Group:

The disasters of Fukushima and Chernobyl are urging the entire world to quickly end the use of atomic energy, and many call for a fossil fuel lockdown to catalyze a climate revolution alongside the transition. Contrary to what is often claimed, nuclear energy cannot make a contribution to climate protection, but only creates immense problems with toxic radioactivity emissions, nuclear waste, atomic bomb material and the dangers of a nuclear catastrophe. In contrast, 100% renewable energies until 2030 can help achieve climate protection and a simultaneous nuclear phase-out, according to a recently published statement by a world-leading group of energy researchers from the USA, EU and Australia.

Their research suggests that a 100% renewable energy supply, including storage systems, can provide full energy security for all of mankind by 2030 and will even be cheaper than the existing nuclear and fossil energy supply, and with over 30% of global electricity already from renewables, momentum is strong. The only requirement for implementation is the right decisions taken by decision makers both in governments and industry. All technical and economic prerequisites for a disruptive conversion of the global energy supply to 100% renewable energies are already in place.

Hon. Peter Rae AO, President of WWEA and Honorary Chairman of the REN Alliance:

40 years ago, the idea of developing nuclear power appealed to me as a non-polluting method of generating electricity. So I studied it. How to deal with waste and how to ensure it would not create a danger to life. Along came Chernobyl and other accidents. Storage of waste was leaving dangerous hiding places while some waste was alleged to be dumped at sea. I became more and more concerned. There were demonstrations that the existing methods were dangerous and required very strict construction and operational tolerances - up went the cost. Long delays and huge cost increases. I had visited nuclear power stations and talked to expert proponents in UK, France, US, Taiwan and Australia, and debates such as New Zealand's electricity future reflect similar concerns. The more I did the more certain I became that it was not the way to go. Then Fukushima put the dangers and cost beyond doubt.

Let's get on with the rollover to renewables.

Dr. Marit Brommer, Executive Director of the International Geothermal Association IGA:

The IGA is proud to work with all renewable energy associations to continuously provide a unified voice to a cleaner energy future. The Geothermal sector is proven to be a partner of choice for many locations in the world serving baseload power and clean heat to customers. We are particularly interested in the increased attention system integration gets, which underpins the importance of all renewables coming together at events such as the webinar organised by the WWEA.

Christian Rakos, President of the World Bioenergy Association:

The IPCC has emphasized the important role of sustainable bioenergy for climate protection. Recent advances in technology allow us to use feedstock from forestry, wood processing and agricultural production in an efficient and clean way. Today, bioenergy already contributes 12 - 13% to global final energy demand. Importantly, contribution from bioenergy is more than 5 times as much as nuclear energy worldwide. Together with other renewable energy technologies such as solar, wind, geothermal and hydropower, bioenergy can increase the contribution in a substantial way to meet the energy demands of all end use sectors and meet the international energy and climate goals.

Stefan Gsanger, Secretary General of the World Wind Energy Association and Co-chair of the Global100RE Platform:

The switch to a renewable energy future requires new political and economic thinking: from centralised structures with few large actors towards decentralised, participatory models with millions of communities and citizens playing an active role, not only as consumers but also as producers of energy. To make this new paradigm the predominant energy paradigm is the true challenge of the energy transformation which we as the world community are facing. If we manage this shift well and on time, billions of people across the globe, in industrialised and developing countries alike, will benefit and will face a bright future.

DOE LNG Export Approvals expand flexibility for Cheniere's Sabine Pass and Corpus Christi to ship to non-FTA countries, boosting U.S. supply to Europe while advancing methane emissions reductions and strengthening global energy security.

Key Points

DOE LNG export approvals authorize Sabine Pass and Corpus Christi to sell full-capacity LNG to non-FTA markets.

✅ Exports allowed to any non-FTA country, including Europe

✅ Capacity covers Sabine Pass and Corpus Christi terminals

✅ DOE targets methane reductions across oil and gas

The U.S. Department of Energy (DOE) today issued two long-term orders authorizing liquefied natural gas (LNG) exports from two current operating LNG export projects, Cheniere Energy Inc.’s Sabine Pass in Louisiana and Corpus Christi in Texas, following a recent deep freeze that slammed the American energy sector.

The two orders allow Sabine Pass and Corpus Christi additional flexibility to export the equivalent of 0.72 billion cubic feet per day of natural gas as LNG to any country with which the U.S. does not have a free trade agreement, including all of Europe, such as the UK natural gas market as well.

While U.S. exporters are already exporting at or near their maximum capacity, with today's issuances, every operating U.S. LNG export project has approval from DOE to export its full capacity to any country where not prohibited by U.S. law or policy constraints in place.

The U.S. is now the top global exporter of LNG and exports are set to grow an additional 20% beyond current levels by the end of this year as additional capacity comes online, even as a domestic energy crisis influences electricity and gas markets.  In January 2022, U.S. LNG supplied more than half of the LNG imports into Europe for the month.

With the expected rise in LNG exports, DOE is particularly focused on driving down methane emissions in the oil and gas sector both domestically and abroad, leveraging the deep technical expertise of the Department, and supporting nuclear innovation as well.

U.S. LNG remains an important component to global energy security worldwide and DOE remains committed to finding ways to help our allies and trading partners, including support to Ukraine and others with the energy supplies they need while continuing to work to mitigate the impact of climate change.

US Renewable Energy Transition is the shift from fossil fuels to wind, solar, and nuclear, targeting net-zero emissions via grid modernization, battery storage, and new transmission to replace legacy plants and meet rising electrification.

Key Points

The move to decarbonize electricity by scaling wind, solar, and nuclear with storage and transmission upgrades.

✅ Falling LCOE makes wind and solar competitive with gas and coal.

✅ 4-hour lithium-ion storage shifts solar to evening peak demand.

✅ New high-voltage transmission links resource-rich regions to load.

Generating electricity to power homes and businesses is a significant contributor to climate change. In the United States, one quarter of greenhouse gas emissions come from electricity production, according to the Environmental Protection Agency.

Solar panels and wind farms can generate electricity without releasing any greenhouse gas emissions, and recent research suggests wind and solar could meet about 80% of U.S. demand with supportive infrastructure. Nuclear power plants can too, although today’s plants generate long-lasting radioactive waste, which has no permanent storage repository.

But the U.S. electrical sector is still dependent on fossil fuels. In 2021, 61 percent of electricity generation came from burning coal, natural gas, or petroleum. Only 20 percent of the electricity in the U.S. came from renewables, mostly wind energy, hydropower and solar energy, according to the U.S. Energy Information Administration, and in 2022 renewable electricity surpassed coal nationwide as portfolios shifted. Another 19 percent came from nuclear power.

The contribution from renewables has been increasing steadily since the 1990s, and the rate of increase has accelerated, with renewables projected to reach one-fourth of U.S. generation in the near term. For example, wind power provided only 2.8 billion kilowatt-hours of electricity in 1990, doubling to 5.6 billion in 2000. But from there, it skyrocketed, growing to 94.6 billion in 2010 and 379.8 billion in 2021.

That’s progress, as the U.S. moves toward 30% electricity from wind and solar this decade, but it’s not happening fast enough to eliminate the worst effects of climate change for our descendants.

“We need to eliminate global emissions of greenhouse gases by 2050,” philanthropist and technologist Bill Gates wrote in his 2023 annual letter. “Extreme weather is already causing more suffering, and if we don’t get to net-zero emissions, our grandchildren will grow up in a world that is dramatically worse off.”

And the problem is actually bigger than it looks, even as pathways to zero-emissions electricity by 2035 are being developed.

“We need not just to create as much electricity as we have now, but three times as much,” says Saul Griffith, an entrepreneur who’s sold companies to Google and Autodesk and has written books on mass electrification. To get to zero emissions, all the cars and heating systems and stoves will have to be powered with electricity, said Griffith. Electricity is not necessarily clean, but at least it it can be, unlike gas-powered stoves or gasoline-powered cars.

The technology to generate electricity with wind and solar has existed for decades. So why isn’t the electric grid already 100% powered by renewables? And what will it take to get there?

First of all, renewables have only recently become cost-competitive with fossil fuels for generating electricity. Even then, prices depend on the location, Paul Denholm of the National Renewable Energy Laboratory told CNBC.

In California and Arizona, where there is a lot of sun, solar energy is often the cheapest option, whereas in places like Maine, solar is just on the edge of being the cheapest energy source, Denholm said. In places with lots of wind like North Dakota, wind power is cost-competitive with fossil fuels, but in the Southeast, it’s still a close call.

Then there’s the cost of transitioning the current power generation infrastructure, which was built around burning fossil fuels, and policymakers are weighing ways to meet U.S. decarbonization goals as they plan grid investments.

“You’ve got an existing power plant, it’s paid off. Now you need renewables to be cheaper than running that plant to actually retire an old plant,” Denholm explained. “You need new renewables to be cheaper just in the variable costs, or the operating cost of that power plant.”

There are some places where that is true, but it’s not universally so.

“Primarily, it just takes a long time to turn over the capital stock of a multitrillion-dollar industry,” Denholm said. “We just have a huge amount of legacy equipment out there. And it just takes awhile for that all to be turned over.”

Intermittency and transmission
One of the biggest barriers to a 100% renewable grid is the intermittency of many renewable power sources, the dirty secret of clean energy that planners must manage. The wind doesn’t always blow and the sun doesn’t always shine — and the windiest and sunniest places are not close to all the country’s major population centers.

Wind resources in the United States, according to the the National Renewable Energy Laboratory, a national laboratory of the U.S. Department of Energy.
Wind resources in the United States, according to the the National Renewable Energy Laboratory, a national laboratory of the U.S. Department of Energy.

The solution is a combination of batteries to store excess power for times when generation is low, and transmission lines to take the power where it is needed.

Long-duration batteries are under development, but Denholm said a lot of progress can be made simply with utility-scale batteries that store energy for a few hours.

“One of the biggest problems right now is shifting a little bit of solar energy, for instance, from say, 11 a.m. and noon to the peak demand at 6 p.m. or 7 p.m. So you really only need a few hours of batteries,” Denholm told CNBC. “You can actually meet that with conventional lithium ion batteries. This is very close to the type of batteries that are being put in cars today. You can go really far with that.”

So far, battery usage has been low because wind and solar are primarily used to buffer the grid when energy sources are low, rather than as a primary source. For the first 20% to 40% of the electricity in a region to come from wind and solar, battery storage is not needed, Denholm said. When renewable penetration starts reaching closer to 50%, then battery storage becomes necessary. And building and deploying all those batteries will take time and money.

SEA Electric school bus conversions bring EV electrification to Type A and Type C fleets, adding V2G, smart charging, battery packs, and zero-emissions performance while extending service life with cost-effective retrofits across US school districts.

Key Points

Retrofit EV drivetrains for Type A and C buses, adding V2G and smart charging to cut emissions and costs.

✅ Converts 10,000 Type A and C school buses over five years

✅ Adds V2G, smart charging, and fleet battery management

✅ Cuts diesel fumes, maintenance, and total cost of ownership

Converting a Porsche 356C to electric power is a challenge. There’s precious little room for batteries, converters, and such. But converting a school bus? That’s as easy as falling off a log, even if adoption challenges persist in the sector today. A bus has acres of space for batteries and the electronics need to power an electric motor.

One of the dumbest ideas human beings ever came up with was sealing school children inside a diesel powered bus for the trip to and from school. Check out our recent article on the impact of fossil fuel pollution on the human body. Among other things, fine particulates in the exhaust gases of an internal combustion engine have been shown to lower cognitive function. Whose bright idea was it to make school kids walk through a cloud of diesel fumes twice a day when those same fumes make it harder for them to learn?

Help may be on the way, as lessons from the largest e-bus fleet offer guidance for scaling. SEA Electric, a provider of electric commercial vehicles originally from Australia and now based in Los Angeles has stuck a deal with Midwest Transit Equipment to convert 10,000 existing school buses to electric vehicles over the next five years. Midwest will provide the buses to be converted to the SEA Drive propulsion system. SEA Electric will complete the conversions using its “extensive network of up-fitting partners,” Nick Casas, vice president of sales and marketing for SEA Electric, says in a press release.

After the conversions are completed, the electric buses will have vehicle to grid (V2G) capability that will allow them to help balance the local electrical grid, where state power grids face new demands, and “smart charge” when electricity prices are lowest. The school buses to be converted are of the US school bus class Type A  or Type C. Type A is the smallest US school bus with a length of 6 to 7.5 metres and is based on a van chassis. The traditional Type C school buses are built on truck architectures.

SEA Electric says that the conversion will extend the life of the buses by more than ten years, with early deployments like B.C. electric school buses demonstrating real-world performance, and that two to three converted buses can be had for the price of one new electric bus. Mike Menyhart, chief strategy officer at SEA Electric says, “The secondary use of school buses fitted with all-electric drivetrains makes a lot of sense. It keeps costs down, opens up considerable availability, creates green jobs right here in the US, all while making a difference in the environment and the health of the communities we serve.”

According to John McKinney, CEO of Midwest Transport Equipment, the partnership with SEA Electric will ensure that it can respond more quickly to customers’ needs as policies like California's 2035 school-bus mandate accelerate demand in key markets. “As the industry moves towards zero emissions we are positioned well with our SEA Electric partnership to be a leader of the electrification movement.”

According to Nick Casas, SEA Electric will plans to expand it operations to the UK soon, and intends to do business in six countries in Europe, including Germany, in the years to come. SEA says it will have delivered more than 500 electric commercial vehicles in 2021 and plans to put more than 15,000 electric vehicles on the road by the end of 2023. Just a few weeks ago, SEA Electric announced an order for 1,150 electric trucks based on the Toyota Hino cargo van for the GATR company of California, highlighting truck fleet power needs that utilities must plan for today.

Electric school buses make so much sense. No fumes to fog young brains, lower maintenance costs, and lower fuel costs are all pluses, especially as bus depot charging hubs scale across markets, adding resilience. Extending the service life of an existing bus by a decade will obviously pay big dividends for school bus fleet operators like MTE. It’s a win/win/win situation for all concerned, with the possible exception of diesel mechanics. But the upside there is they can be retrained in how to maintain electric vehicles, a skill that will be in increasing demand as the EV revolution picks up speed.

Nature-friendly offshore wind energy supports climate neutrality by reducing greenhouse gases while safeguarding marine biodiversity through EU marine spatial planning, ecosystem-based approaches, cross-border coordination, and zero-use zones for resilient seas.

Key Points

An approach to offshore wind that cuts emissions while respecting ecological limits and protecting marine biodiversity.

✅ Aligns buildout with ecological limits and marine spatial plans

✅ Minimizes noise, collision, and habitat loss for sensitive species

✅ Coordinates EU-wide monitoring, data, and cross-border siting

Offshore wind power can help reduce greenhouse gas emissions, but it poses risks for the seas. Germany will hold the EU Council Presidency and the North Sea Energy Cooperation Presidency in 2020. What must be done to contain the climate and species crises, as it were?

Offshore wind power is an important regenerative energy source with a $1 trillion market outlook in the coming decades. However, the construction, operation and maintenance of the systems put marine mammals, birds and fish at considerable risk. Photo: Siemens AG

In order to achieve the German and EU climate and energy goals by 2030 and climate neutrality by 2050, we need a nature-friendly energy transition. At present, the European energy system is largely based on fossil fuels. This is changing, as renewables surge across Europe for end consumers and industry and the large-scale electrification of the energy consumption sectors. Offshore wind energy is an element for future power generation.

A nature-friendly energy transition is only possible if energy consumption is reduced and energy efficiency is maximized in all applications and sectors. Emissions reductions through offshore wind energy In 2019, Europe had an installed offshore wind energy capacity of around 22 gigawatts from 5,047 grid-connected wind turbines in twelve countries. In Germany, the nominal output of the offshore wind turbines feeding into the German power grid was around 7.5 gigawatts, with clean energy accounting for about 50% of electricity nationwide. The wind blows much stronger and more steadily at sea than on land.

The power capacity of the turbines has also almost doubled in the last five years, which has led to a higher energy yield. Offshore wind energy is a building block for replacing fossil fuels, and markets like the U.S. offshore sector are about to soar as well. Wind turbines at sea provide electricity almost every hour of the year and have operating hours that are as high as conventional power plants. They can contribute to significant reductions in CO2 emissions and to mitigate the climate crisis.

It must be ensured that offshore wind turbines and parks as well as the grid infrastructure make a positive contribution to climate protection through their expansion and that the overall condition of marine ecosystems improves. The expansion of offshore wind energy is necessary from the point of view of climate science and must take place within the framework of the ecological load limits and under nature conservation aspects.

Seas and marine ecosystems suffer from years of overfishing, pollution and industrial use. The conservation status of sea birds, marine mammals and fish stocks is poor. Ecosystem services and productivity of the oceans are decreasing as a result of massive species extinction and unfavorable habitats. Changes in sea temperature, oxygen levels and acidification of the oceans reduce their resilience to the climate crisis.

The latest reports from the European Environment Agency show in black and white that the good environmental status and other goals of the Marine Strategy Framework Directive are not being achieved. The primary goal must therefore be to meet the obligations of the Marine Strategy Framework Directive and the EU nature conservation directives.

With the expansion of offshore wind energy, the pressure on the already polluted marine ecosystems is increasing. Offshore wind turbines also harbor risks for marine ecosystems, especially if they are built in unfavorable locations. Studies show harmful effects on marine mammals, birds, fish and the ocean floor. In Europe, where wind power investments hit $29.4 billion last year, a regulatory framework must be created for the expansion of offshore wind energy within the ecological limits and taking into account zero-use zones. The European Union urgently needs to take coherent measures for healthy and resilient seas.

New strategy of the European Commission The EU Commission plans to present a strategy for the expansion of renewable energies at sea on November 18, 2020.

The strategy will address the opportunities and challenges associated with the expansion of renewable energies at sea, such as effects on energy networks and markets, management of the maritime space, the technological transfer of research projects, regional and international cooperation and industrial policy dimensions, as well as political headwinds in some countries that can affect project pipelines. NABU welcomes the strategy, but worries about insufficient consideration of marine protection, ecological load-bearing capacity and the marine spatial planning that regulates interests in the use of the sea. All EU member states have to submit their marine spatial planning plans by March 2021.

Conclusions of the European Council Shortly before the end of 2020, the European Council plans to adopt conclusions for cooperation among European member states on the subject of offshore wind energy and other renewable energy sources at sea. It is important that the planning and development of offshore wind energy is coordinated across national borders, including alignment with the UK's offshore wind growth, also to protect marine ecosystems.

However, the ecosystem approach must not be left out. It must be ensured that the Council conclusions focus on the implementation of EU marine and nature conservation directives for the expansion of offshore wind energy within the load limits. EU-wide monitoring systems can help protect marine species and ecosystems. Germany holds the EU Council Presidency and the North Sea Energy Cooperation Presidency for 2020 and can make a decisive contribution.

NABU demands on offshore wind energy in Europe Expansion targets for offshore wind energy across Europe should be based on the ecological load limits of the seas. Development of concrete concepts for the ecological upgrading of areas in marine spatial planning and operationalization of the ecosystem-based approach.

For the nature-friendly expansion of offshore – Wind energy systems must take into account avoidance distances from seabirds to turbines, habitat loss, collision risks and cumulative effects. Implementation / obligation to sensitivity analyzes – they allow targeted conclusions about the best possible locations for offshore wind energy without conflicts with marine protection.

Targeted keeping of areas free for species and their Habitats of anthropogenic use – this increases planning security and can lower investment thresholds for EU funding programs. Ensuring regional cooperation between the European member states for nature Protection and with the involvement of nature conservation authorities – after all, the marine ecosystem does not stop at borders.

Adjustment of priorities: If offshore wind energy is prioritized over other renewable energy sources across Europe, other industrial forms of use of the seas must be given a lower priority.

California 100% Clean Energy by 2030 proposes accelerating SB 100 with solar, wind, offshore wind, and battery storage to decarbonize the grid, enhance reliability, and reduce blackouts, leveraging transmission upgrades and long-duration storage solutions.

Key Points

Proposal to accelerate SB 100 to 2030, delivering a carbon-free grid via renewables, storage, and new transmission.

✅ Accelerates SB 100 to a 2030 carbon-free electricity target

✅ Scales solar, wind, offshore wind, and battery storage capacity

✅ Requires transmission build-out and demand response for reliability

Amid a spate of wildfires that have covered large portions of California with unhealthy air, an environmental group that frequently lobbies the Legislature in Sacramento is calling on the state to accelerate by 15 years California's commitment to derive 100 percent of its electricity from carbon-free sources.

But skeptics point to last month's pair of rolling blackouts and say moving up the mandate would be too risky.

"Once again, California is experiencing some of the worst that climate change has to offer, whether it's horrendous air quality, whether it's wildfires, whether it's scorching heat," said Dan Jacobson, state director of Environment California. "This should not be the new normal and we shouldn't allow this to become normal."

Signed by then-Gov. Jerry Brown in 2018, Senate Bill 100 commits California by 2045 to use only sources of energy that produce no greenhouse gas emissions to power the electric grid, a target that echoes Minnesota's 2050 carbon-free plan now under consideration.

Implemented through the state's Renewable Portfolio Standard, SB 100 mandates 60 percent of the state's power will come from renewable sources such as solar and wind within the next 10 years. By 2045, the remaining 40 percent can come from other zero-carbon sources, such as large hydroelectric dams, a strategy aligned with Canada's electricity decarbonization efforts toward climate pledges.

SB 100 also requires three state agencies _ the California Energy Commission, the California Public Utilities Commission and the California Air Resources Board _ to send a report to the Legislature reviewing various aspects of the legislation.

The topics include scenarios in which SB 100's requirements can be accelerated. Following an Energy Commission workshop earlier this month, Environment California sent a six-page note to all three agencies urging a 100 percent clean energy standard by 2030.

The group pointed to comments by Gov. Gavin Newsom after he toured the devastation in Butte County caused by the North Complex fire.

"Across the entire spectrum, our (state) goals are inadequate to the reality we are experiencing," Newsom said Sept. 11 at the Oroville State Recreation Area.

Newsom "wants to look at his climate policies and see what he can accelerate," Jacobson said. "And we want to encourage him to take a look at going to 100 percent by 2030."

Jacobson said Newsom cam change the policy by issuing an executive order but "it would probably take some legislative action" to codify it.

However, Assemblyman Jim Cooper, a Democrat from the Sacramento suburb of Elk Grove, is not on board.

"I think someday we're going to be there but we can't move to all renewable sources right now," Cooper said. "It doesn't work. We've got all these burned-out areas that depend upon electricity. How is that working out? They don't have it."

In mid-August, California experienced statewide rolling blackouts for the first time since 2001.

The California Independent System Operator _ which manages the electric grid for about 80 percent of the state _ ordered utilities to ratchet back power, fearing the grid did not have enough supply to match a surge in demand as people cranked up their air conditioners during a stubborn heat wave that lingered over the West.

The outages affected about 400,000 California homes and businesses for more than an hour on Aug. 14 and 200,000 customers for about 20 minutes on Aug. 15.

The grid operator, known as the CAISO for short, avoided two additional days of blackouts in August and two more in September thanks to household utility customers and large energy users scaling back demand.

CAISO Chief Executive Officer Steve Berberich said the outages were not due to renewable energy sources in California's power mix. "This was a matter of running out of capacity to serve load" across all hours, Berberich told the Los Angeles Times.

California has plenty of renewable resources _ especially solar power _ during the day. The challenge comes when solar production rapidly declines as the sun goes down, especially between 7 p.m. and 8 p.m. in what grid operators call the "net load peak."

The loss of those megawatts of generation has to be replaced by other sources. And in an electric grid, system operators have to balance supply and demand instantaneously, generating every kilowatt that is demanded by customers who expect their lighting/heating/air conditioning to come on the moment they flip a switch.

Two weeks after the rotating outages, the State Water Resources Control Board voted to extend the lives of four natural gas plants in the Los Angeles area. Natural gas accounts for the largest single source of California's power mix _ 34.23 percent. But natural gas is a fossil fuel, not a carbon-free resource.

Jacobson said moving the mandate to 2030 can be achieved by more rapid deployment of renewable sources across the state.

The Public Utilities Commission has already directed power companies to ramp up capacity for energy storage, such as lithium-ion batteries that can be used when solar production falls off.

Long-term storage is another option. That includes pumped hydro projects in which hydroelectric facilities pump water from one reservoir up to another and then release it. The ensuing rush of water generates electricity when the grid needs it.

Environment California also pointed to offshore wind projects along the coast of Central and Northern California that it estimates could generate as much as 3 gigawatts of power by 2030 and 10 gigawatts by 2040. Offshore wind supporters say its potential is much greater than land-based wind farms because ocean breezes are stronger and steadier.

Gary Ackerman, a utilities and energy consultant with more than four decades of experience in power issues affecting states in the West, said the 2045 mandate was "an unwise policy to begin with" and to accommodate a "swift transition (to 2030), you're going to put the entire grid and everybody in it at risk."

But Ackerman's larger concern is whether enough transmission lines can be constructed in California to bring the electricity where it needs to go.

"I believe Californians consider transmission lines in their backyard about the same way they think about low-income housing _ it's great to have, but not in my backyard," Ackerman said. "The state is not prepared to build the infrastructure that will allow this grandiose build-out."

Cooper said he worries about how much it will cost the average utility customer, especially low and middle-income households. The average retail price for electricity in California is 16.58 cents per kilowatt-hour, compared to 10.53 nationally, according to the U.S. Energy Information Administration.

"What's sad is, we've had 110-degree days and there are people up here in the Central Valley that never turned their air conditioners on because they can't afford that bill," Cooper said.

Jacobson said the utilities commission can intervene if costs get too high. He also pointed to a recent study from the Goldman School of Public Policy at UC Berkeley that predicted the U.S. can deliver 90 percent clean, carbon-free electric grid by 2035 that is reliable and at no extra cost in consumers' bills.

"Every time we wait and say, 'Oh, what about the cost? Is it going to be too expensive?' we're just making the cost unbearable for our kids and grandkids," Jacobson said. "They're the ones who are going to pay the billions of dollars for all the remediation that has to happen ... What's it going to cost if we do nothing, or don't go fast enough?"

The joint agency report on SB 100 from the Energy Commission, the Public Utilities Commission and the Air Resources Board is due at the beginning of next year.
