One State Generates Much, Much More Renewable Energy Than Any Other – and It’s Not California

At-a-Glance

A new batch of data about the country’s electricity generation shows the increasing dominance of one state as the clean energy leader. No, it’s not California. It’s Texas. For more, read One State Generates Much, Much More Renewable Energy Than Any Other – and It’s Not California.

Key Takeaways

  • Texas has produced more gigawatt-hours of electricity from renewable sources than any other state for several years running, thanks largely to wind energy.
  • In 2022, Texas generated 136,118 gigawatt-hours from wind and utility-scale solar, most of it from wind. The runner-up was California with 52,927 gigawatt-hours, most of it from utility-scale solar, according to the Energy Information Administration.
  • If we include all renewable energy – like hydropower, biomass, and others – then Texas is still the leader with 138,538 gigawatt-hours, followed by Washington, whose 91,148 gigawatt-hours mostly came from hydropower, and then California, which also has a lot of hydropower, with 89,473 gigawatt-hours.
  • If we include all carbon-free electricity sources, including renewables and nuclear, the leader is again Texas, with 180,145 gigawatt-hours, followed by Illinois with 124,055 gigawatt-hours, most of it from nuclear.
  • Another important part of the conversation is rooftop solar. Add small-scale solar to the state totals, Texas would still be ahead, but the lead wouldn’t be quite so big. California dominates in small-scale solar with 23,094 gigawatt-hours, which is about seven times the number from Texas.

Path to 100% Perspective

The latest data on electricity generation in the U.S., while encouraging, shows that there is much work to be done if the country is to achieve 100% renewable energy. Passage of the Inflation Reduction Act (IRA) in August 2022 could be the spark that is needed and act as a key driver in the energy transition. The most important element of the IRA is its tax credits, which have a history of being effective. Tax credits lower the upfront capital investment cost of clean power and incentivize renewable electricity production. This will encourage companies to invest increasingly in clean energy technologies and technologies accelerating the progress to the net-zero goal.

Uncovering the Hidden Value of Reciprocating Engines in Today’s Energy Markets

At-a-Glance

Electric utilities could be missing out on millions of dollars in value by using outdated grid modeling techniques. It is critical for a company to determine the optimum asset mix in order to remain competitive throughout the energy transition. Reuters, in collaboration with Wärtsilä, developed a report to outline the limitations of traditional grid modeling in the United States, explore how reciprocating engines capture value, and explain strategic pathways to a renewable energy transition. For more, read Uncovering the Hidden Value of Reciprocating Engines in Today’s Energy Markets.

Key Takeaways

  • A recent analysis by Ascend Analytics shows the use of hourly dispatch modeling for grid planning vastly underestimates the value of flexible grid resources such as batteries and utility-scale reciprocating internal combustion engines (RICE). This is due to the use of normalized weather inputs that fail to capture real-life grid conditions with significant levels of variable renewable energy and failing to drill down to the five-minute level where much of the variability occurs.
  • As variable generation sources increasingly dominate U.S. grids, flexible assets such as batteries and RICE units are better suited to compensate for the gaps in renewable output because they can operate only when necessary. However, since these flexible assets act on sub-hourly timeframes, the value they provide to the grid is not captured in traditional daily or hourly models.
  • According to the Ascend study, RICE units appeared to be the most expensive of three dispatchable gas technologies when using an hourly model. The use of five-minute modeling shows the opposite to be true: RICEs deliver greater value than competing technologies, providing ratepayers with a lower cost solution in a world of growing renewable generation and pricing volatility.
  • Due to the variable nature of renewable resources, sub-hourly pricing volatility is set to increase dramatically across U.S. electric grids. A move to more granular production models will assist regulators and network planners in selecting technologies, like RICE units, that are best suited to increasingly volatile pricing conditions.

Path to 100% Perspective

The research outlined in the white paper clearly demonstrates the need to update resource planning models to account for real-time, five-minute variability in high renewable systems. It shows that commonly used methodologies for grid planning in the United States may result in suboptimal outcomes for ratepayers.

Following passage of the 2022 Inflation Reduction Act, the United States is about to unleash new levels of variable renewable energy generation. Consequently, there is an urgent need for regulators to be made aware of the shortcomings of traditional hourly and weather-normalized modeling in forecasting current energy system dynamics. Without regulatory pressure to use more granular models, there will be little incentive for U.S. electric utilities to embrace sub-hourly models. This will lead to increasingly suboptimal results and rising costs for ratepayers, while electric utilities invest millions in assets that are poorly equipped to operate in a low-carbon energy world. Given the forecasted rate of increase in renewables on the grid, the shift to capture these fundamental dynamics is one that cannot wait.

DOE eyes AI, machine learning to accelerate long-duration energy storage research

At-a-Glance:

A proposed federal research program to accelerate research into the durability and performance of long-duration energy storage is a critical step to meeting the Biden administration’s decarbonization goals, speakers said Thursday at a Department of Energy (DOE) panel. DOE officials said long-duration energy storage technology must be commercially ready, at scale, by 2030, in order to increase the share of renewables on the grid and meet the administration’s 100% clean electricity by 2035 goal. To learn more, read, “DOE eyes AI, machine learning to accelerate long-duration energy storage research.”

Key Takeaways:

  • In July, DOE announced a moonshot goal to reduce the cost of utility-scale, long-duration storage by 90% within a decade, backed by federal research, large-scale demonstrations and domestic manufacturing incentives
  • Deputy Energy Secretary David Turk said bringing long-duration storage to the grid wouldn’t just make it possible to rely on more renewable energy, but also “increase resilience and lower energy burdens” for vulnerable communities.
  • Although there have been technical breakthroughs on long-duration technologies — notably Form Energy’s July announcement of a 100-hour iron-air battery — experts have cautioned about the limited window to test batteries in the real world.
    • ROVI, the proposed initiative from DOE’s national labs, seeks to close that information gap by using machine learning and artificial intelligence to model performance of different long-duration storage technologies, including predicting how the technology will lose performance or hold up physically over time.

Path to 100% Perspective:

Artificial Intelligence (AI) and Machine Learning (ML) will be key elements for the design of future energy systems, supporting the growth of smart grids and improving the efficiency of power generation, along with the interaction among electricity customers and utilities. Centralized power systems enable equal access to clean power at the lowest cost, reducing economic inequality. Regardless of whether the path forward is more or less centralized, AI brings value to all parties. The more AI is used in the dispatch of power plants, the more it will be needed in the design and creation process for new power plants or aggregations of power generation equipment. AI and equipment expertise are needed to enhance the safety, reliability, and efficiency of power equipment and systems. AI and machine learning will play increasingly important roles in future power generation, especially as more communities and organizations come to rely on smart grids and renewable fuels for their electricity needs.

Wärtsilä & Schneider Electric develop power system reference design for lithium mines lacking grid access

At-a-Glance:

Technology group Wärtsilä and Schneider Electric say they have together developed a “unique, end-to-end power system reference design.” It is aimed specifically at lithium mine operations where there is no access to a grid supply of electricity. To learn more, read “Wärtsilä & Schneider Electric develop power system reference design for lithium mines lacking grid access.” 

Key Takeaways:

  • Wärtsilä and Schneider Electric signed the framework cooperation agreement for the development of the design for mining energy solutions in March 2020.
  • Their design provides for an economically viable total expenditure that covers the complete process, including consulting, project design, the power infrastructure, equipment delivery, installation and commissioning.
  • Their solution contributes to sustainable lithium production by optimising the efficient delivery and use of energy, and by leveraging microgrids and enabling renewable energy sources.
  • The overall objective of this collaborative development is to provide high efficiency power solutions with a minimal environmental footprint for the mining industry.

Path to 100% Perspective:

Increasing global demand for lithium that is used in battery storage applications is putting pressure on mining operations to be as efficient and cost-effective as possible. How mines source and use power is a key element in this process. By using microgrids and renewable energy sources to meet their power needs, mine operators will reduce environmental impact and take the necessary steps toward decarbonization.

Texas must increase ties to the national grid and DER to avoid another power catastrophe, analysts say

At-a-Glance:

Texans were left in the cold and dark this February, following extreme cold weather that had the Texas competitive energy market unable to prevent deadly power failures. Leaving behind its historic commitment to power system independence and joining the larger U.S. grid can relieve some of the consequences of extreme weather events Texas is likely to see again, many energy analysts in and out of Texas said. To learn more, read “Texas must increase ties to the national grid and DER to avoid another power catastrophe, analysts say.”

Key Takeaways:

  • “We designed this system for Ozzie and Harriet weather and we now have Mad Max,” said Texas energy consultant Alison Silverstein.
  • Some customers discovered variable bill plans can come with price spikes.
  • “The theory is that a high price will bring investments, but people don’t invest in things that might only make money sometime in the future unless they are required to,” said Jussi Heikkinen, North America Director of Growth and Development for global power plant developer Wärtsilä.

Path to 100% Perspective:

Texas does not have firm rules on power plant engineering for ambient temp ranges. Recommendations from ERCOT were published after the 2011 blackouts, but they are not mandatory, like they are in the eastern part of the country The Texas blackouts are an urgent indication that recommendations should be turned into common-sense regulation that leads to grid reliability and ratepayer protection.

McKinsey: Low Cost Renewables Will Outcompete Fossil Assets By 2030

At-a-Glance:

The energy transition is accelerating. In 2020, renewables outpaced fossil fuels in Europe for the first time. According to the latest research from McKinsey, demand for fossil fuels will never return to pre-pandemic levels. To learn more, read “McKinsey: Low Cost Renewables Will Outcompete Fossil Assets By 2030.” Reading this article may require a subscription.

 

Key Takeaways:

  • McKinsey’s 2021 Global Energy Perspective Report predicts that fossil fuel demand is set to peak globally by 2029 and that by 2036, half of the global power supply will be generated by intermittent renewable energy sources.
  • While an earlier peak in hydrocarbon demand means a substantial reduction in forecasted carbon emissions, the world remains significantly off the 1.5°C pathway and will run out of its carbon budget for 2100 in the early 2030s.
  • Many pandemic related recovery packages are providing significant support to the hydrocarbon industry. The 2020 Climate Transparency Report said that by mid-October 2020, G20 countries had spent nearly $400 billion on support for the energy sector – with 53.5% going to the fossil fuel sector.
  • McKinsey’s Christer Tryggestad concludes: “According to our estimates, annual emissions would need to be around 50 percent lower in 2030 and about 85 percent lower by 2050 than current trends predict to limit the global temperature increase to 1.5°C.”

 

Path to 100% Perspective:

The shift toward renewable energy sources over fossil fuels appears to be the way forward. Governments around the world will need to use this shift as motivation to put policies in place that encourage greater investment in renewable energy. There is a tremendous opportunity in this moment for G20 countries, which are responsible for around 75% of global emissions, to rethink their energy investments and bank on low-cost renewables to meet net-zero targets and pave the way for a 100% renewable energy future.

The 10 Ways Renewable Energy’s Boom Year Will Shape 2021

At-a-Glance:

With the uncertainty of 2020 behind us, the new year kicked off with surging growth for renewable energy. Growth will likely continue into 2021, fueled in part by last year’s major turning points. Some analysts have started predicting that the U.S. power sector is approaching peak natural gas. That would leave room for solar-panel installations to build on the ongoing boom. To learn more, read “The 10 Ways Renewable Energy’s Boom Year Will Shape 2021.” Reading this article may require a subscription. 

Key Takeaways:

  • Although U.S. residential solar installations dropped nearly 20% in the second quarter of 2020 from the first, by the end of the year, the sector bounced back and the country added 19 gigawatts of total solar power.
  • New battery capacity in the U.S. more than doubled in the third quarter of 2020 from the second, according to Wood Mackenzie and the U.S. Energy Storage Association. Projects in California were a key reason for the surge.
  • Electricity from Spain’s solar farms was up over 60% in 2020 compared to 2019, generating over 15,000 gigawatt hours of power, according to data from the country’s grid manager Red Electrica.
  • Renewable power beat out fossil fuels in the European Union for the first time, with approximately 40% of electricity in the first half of 2020 coming from renewable sources compared with 34% from plants burning fossil fuels.

Path to 100% Perspective:

Despite the upheaval caused by COVID-19 in 2020, the demand for renewable energy has not slowed and the path to 100% is becoming clearer as countries around the world commit to carbon-free sources of electricity. Developments such as China’s commitment to reaching carbon neutrality by 2060 and the European Union’s shift to renewables as the dominant power source provide further evidence that the tide is turning toward decarbonization. Ambitious goals, a commitment to research and development, and ongoing collaboration will continue to pave the path to a renewable energy future.

Q&A Series: Joseph Kopser Offers His Strategic View to Energy Innovations

Kopser is a technology entrepreneur and expert in transportation, smart cities, urban mobility, energy, national security issues as well as an Army combat veteran.

 

Question: Could you please describe you and your work?

Joseph: I am a serial entrepreneur and expert in energy and national security issues. Currently, I serve as an Executive-in-Residence at the McCombs School of Business at the University of Texas. In addition, I am President of Grayline after co-founding and serving as CEO of RideScout before it was acquired by Mercedes. I served in the U.S. Army for 20 years earning the Combat Action Badge, Army Ranger Tab and Bronze Star. I am a graduate of West Point with a BS in Aerospace Engineering and also received a Masters from the Harvard Kennedy School. In 2013, I was recognized as a White House Champion of Change for my efforts in Energy and Transportation. In 2014, RideScout won the U.S. DOT Data Innovation Award and I co-authored the book, Catalyst. I am the Chairman of the Board of Advisors for the CleanTX Foundation, an economic development and professional association for cleantech.

Q: What made you want to join the Path to 100%? 

Joseph: I want to partner with any and all parties that are moving towards a more sustainable energy economy. Some might find it ironic that I was born in a coal state (Kentucky), moved to an oil and gas state (Texas) and now I advocate for a cleaner energy economy. For me, it’s about the triple bottom line– people, profits, and the planet. And the good news is that with an appropriate balance between public and private sector policy goals, we can achieve success for all three elements of the triple bottom line. I see the Path to 100% as just one of the many ways to get there.

Q: Describe your passion for renewable energy and how you have put that to work in the United States.

Joseph: My interest in renewable energy started during my time serving in the military, where I was able to see first hand ways that our lack of a clear energy security policy was threatening our national security. I participated in missions in Iraq that were little more than delivering diesel fuel out to remote military sites with out of date and inefficient generators and motors that were guzzling the fuel. Every time a Soldier went on the road for a delivery, they were at risk from the enemy. It didn’t make sense for the greatest nation in the world (that put a man on the moon in the 1960s) to still be using generators that were made before the Soldiers were even born.

Since that time, I’ve become a clean energy warrior in and out of uniform. My first company, RideScout, set out to reduce our carbon footprint by making transportation more energy efficient. I was co-founder of the DefenseEnergy.com Summit and the National Security Technology Accelerator where both entities were in search of clean energy technologies to benefit the warfight at all aspects of energy production, storage and distribution.

Finally, I chair the board of advisors for CleanTX.org. CleanTX is a clean energy consortium dedicated to accelerate and promote the growth of renewable energy.

Q: How would you like to see your work implemented on a global scale? 

Joseph: First, the US has to be a leader. In the short term, some may perceive it as a cost, but we have to measure the fully burdened costs of our decisions long term. We have to be more willing to take risks, experiment with pilot projects and most importantly learn from our failures of what does and does not work. Finally, we have to align incentives and remind people that you always get what you pay for. Currently, the costs are disproportionately spread across everyone in the economy as opposed to certain producers or consumers that are actually generating the negative externalities. Being serious about some kind of carbon pricing will allow the marketplace to better align to a set of goals that work for people, profits and the planet

Q: What do you believe are the greatest areas of opportunity for your the U.S.’s renewable energy sector?

Joseph: Creating jobs for the 21st century energy economy. Lots of them. Bringing renewable jobs closer to home would allow us to decrease our dependence on foreign fossil fuels. All too often, people fight change when they see it as a threat. It is understandable that people seek economic security for their family and their kids long-term. Therefore, I see the greatest opportunity to bring people along better by demonstrating (not just talking about) how they benefit from clean water, fresher air, and most importantly, higher paying jobs.

Q: Now, what do you see as the primary barriers or challenges the U.S. faces on its path to clean, affordable energy?

Joseph: Fear of losing your job or your livelihood. The way I see it, innovation in the private sector is not enough to successfully reinvent the American energy economy. Partnership with the government that creates the conditions for innovation is essential, both from a funding and regulatory perspective.

The social, economic, and political environment in which we all operate is changing faster than ever, and the pace of change is accelerating. Robotics, autonomous vehicles, smart cities, renewables, 3D printing, and other emerging technologies are colliding with socioeconomic forces such as urbanization, wealth concentration, aging populations, and widespread workforce displacement. At the same time, socio-economic segregation is on the rise in the U.S. and our educational system needs serious changes to meet the challenges of the 21st Century.

You cannot talk about a path to cleaner, more affordable energy without balancing all aspects of change in society that weigh a family down at the kitchen table. All too often, advocates in our industry are only looking at the issue from an environmental standpoint. I recommend they stand back and take a more holistic view.

Q: Finally, how can the U.S. lead in the path to 100 percent renewables? And what progress do you envision for the region over the next few years?

Joseph: We wrote a Constitution that despite its shortcomings has stood the time of time. We overcame the existential threat of the Civil War. We came together to pull ourselves out of the Great Depression. We won World War II and created the first middle class in human history. Thanks to American innovation, rule of law and protection of intellectual property, we have created the conditions with our economy to lift more people out of poverty world-wide than any other invention in human history.

I am confident that if we take all of our best collective talents, and point it in the right direction, there is nothing we cannot accomplish. In building a cleaner energy economy, we will create jobs, educate more people world-wide and leave a much better world for our kids tomorrow.
