Black Hills to build 350 MW plant soon

US Electricity Generation H1 2018 saw wind and solar gains but hydro declines, as natural gas led the grid mix and coal fell; renewables' share, GWh, emissions, and capacity additions shaped the power sector.

Key Points

It is the H1 2018 US power mix, where natural gas led, coal declined, and wind and solar grew while hydro fell.

✅ Natural gas reached 32% of generation, highest share

✅ Coal fell; renewables roughly tied nuclear at ~20%

✅ Wind and solar up; hydro output down vs 2017

To complement our revival of US electricity capacity reports, here’s a revival of our reports on US electricity generation.

As with the fresh new capacity report, things are not looking too bright when it comes to electricity generation. There’s still a lot of grey — in the bar charts below, in the skies near fossil fuel power plants, and in the human and planetary outlook based on how slowly we are cutting fossil fuel electricity generation.

As you can see in the charts above, wind and solar energy generation increased notably from the first half of 2017 to the first half of 2018, and the EIA expected larger summer solar and wind generation in subsequent months, reinforcing that momentum.

A large positive when it comes to the environment and human health is that coal generation dropped a great deal year over year — by even more than renewables increased, though the EIA later noted an increase in coal-fired generation in a subsequent year, complicating the trend. However, on the down side, natural gas soared as it became the #1 source of electricity generation in the United States (32% of US electricity). Furthermore, coal was still solidly in the #2 position (27% of US electricity). Renewables and nuclear were essentially in a tie at 19.8% of generation, with renewables just a tad above nuclear.

Actually, combined with an increase in nuclear power generation, natural gas electricity production increased so much that the renewable energy share of electricity generation actually dropped in the first half of 2018 versus the first half of 2017, even amid declining electricity use in some periods. It was 19.8% this year and 20% last year.

Again, solar and wind saw a significant growth in its market share, from 9% to 9.9%, but hydro brought the whole category down due to a decrease from 9% to 8%.

The visuals above are probably the best way to examine it all. The H1 2018 chart was still dominated by fossil fuels, which together accounted for approximately 60% of electricity generation, even though by 2021 non-fossil sources supplied about 40% of U.S. electricity, highlighting the longer-term shift. In H1 2017, the figure was 59.7%. Furthermore, if you switch to the “Change H1 2018 vs H1 2017 (GWh)” chart, you can watch a giant grey bar representing natural gas take over the top of the chart. It almost looks like it’s part of the border of the chart. The biggest glimmer of positivity in that chart is seeing the decline in coal at the bottom.

What will the second half of the year bring? Well, the gigantic US electricity generation market shifts slowly, even as monthly figures can swing, as January generation jumped 9.3% year over year according to the EIA, reminding us about volatility. There is so much base capacity, and power plants last so long, that it takes a special kind of magic to create a rapid transition to renewable energy. As you know from reading this quarter’s US renewable energy capacity report, only 43% of new US power capacity in the first half of the year was from renewables. The majority of it was from natural gas. Along with other portions of the calculation, that means that electricity generation from natural gas is likely to increase more than electricity generation from renewables.

Washington-Led Lawsuit Against Energy Emergency challenges President Trump's executive order, citing state rights, environmental reviews, permitting, and federal overreach; coalition argues record energy output undermines emergency claims in Seattle federal court.

Key Points

Multistate suit to void Trump's energy emergency, alleging federal overreach and weakened environmental safeguards.

? Challenges executive order's legal basis and scope

? Claims expedited permitting skirts environmental reviews

? Seeks to halt emergency permits for non-emergencies

In a significant legal move, Washington State Attorney General Nick Brown has spearheaded a coalition of 15 states in filing a lawsuit against President Donald Trump's executive order declaring a national energy emergency. The lawsuit, filed in federal court in Seattle on May 9, 2025, challenges the legality of the emergency declaration, which aims to expedite permitting processes for fossil fuel projects in pursuit of an energy dominance vision by bypassing key environmental reviews.

Background of the Energy Emergency Declaration

President Trump's executive order, issued on January 20, 2025, asserts that the United States faces an inadequate and unreliable energy grid, particularly affecting the Northeast and West Coast regions. The order directs federal agencies, including the Army Corps of Engineers and the Department of the Interior, to utilize "any lawful emergency authorities" to facilitate the development of domestic energy resources, with a focus on oil, gas, and coal projects. This includes expediting reviews under the Clean Water Act, Endangered Species Act, the National Environmental Policy Act, and the National Historic Preservation Act, potentially reducing public input and environmental oversight.

Legal Grounds for the Lawsuit

The coalition of states, led by Washington and California, argues that the emergency declaration is an overreach of presidential authority, echoing disputes over the Affordable Clean Energy rule in federal courts. They contend that U.S. energy production is already at record levels, and the declaration undermines state rights and environmental protections. The lawsuit seeks to have the executive order declared unlawful and to halt the issuance of emergency permits for non-emergency projects. 

Implications for Environmental Protections

Critics of the energy emergency declaration express concern that it could lead to significant environmental degradation. By expediting permitting processes, including geothermal permitting, and reducing public participation, the order may allow projects to proceed without adequate consideration of their impact on water quality, wildlife habitats, and cultural resources. Environmental advocates argue that such actions could set a dangerous precedent, enabling future administrations to bypass essential environmental safeguards under the guise of national emergencies, even as the EPA advances new pollution limits for coal and gas plants to address the climate crisis.

Political and Legal Reactions

The Trump administration defends the executive order, asserting that the president has the authority to declare national emergencies and that the energy emergency is necessary to address perceived deficiencies in the nation's energy infrastructure and potential electricity pricing changes debated by industry groups. However, legal experts suggest that the broad application of emergency powers in this context may face challenges in court. The outcome of the lawsuit could have significant implications for the balance of power between state and federal authorities, as well as the future of environmental regulations in the United States.

The legal challenge led by Washington State Attorney General Nick Brown represents a critical juncture in the ongoing debate over energy policy and environmental protection. As the lawsuit progresses through the courts, it will likely serve as a bellwether for future conflicts between state and federal governments regarding the scope of executive authority and the preservation of environmental standards, amid ongoing efforts to expand uranium and nuclear energy programs nationwide. The outcome may set a precedent for how national emergencies are declared and managed, particularly concerning their impact on state governance and environmental laws.

Mexico Energy Reform Defeat underscores opposition unity as CFE-first rules, state regulators, and lithium nationalization falter amid USMCA concerns, investment risks, and clean energy transition impacts in Congress over power generation policy.

Key Points

The failed push to expand CFE control, flagged for USMCA risks, higher costs, regulator shifts, and slower clean energy transition.

✅ Bill to mandate 54% CFE generation and priority dispatch failed.

✅ Opposition cited USMCA breaches, higher prices, slower clean energy.

✅ Lithium nationalization to return via separate legislation.

Mexican President Andres Manuel Lopez Obrador's plan to increase state control of power generation was defeated in parliament on Sunday, as opposition parties united in the face of a bill they said would hurt investment and breach international obligations, concerns mirrored by rulings such as the Florida court on electricity monopolies that scrutinize market concentration.

His National Regeneration Movement (MORENA) and its allies fell nearly 60 votes short of the two-thirds majority needed in the 500-seat lower house of Congress, mustering just 275 votes after a raucous session that lasted more than 12 hours.

Seeking to roll back previous constitutional reforms that liberalized the electricity market, Lopez Obrador's proposed changes would have done away with a requirement that state-owned Comision Federal de Electricidad (CFE) sell the cheapest electricity first, a move reminiscent of debates when energy groups warned on pricing changes under federal proposals, allowing it to sell its own electricity ahead of other power companies.

Under the bill, the CFE would also have been set to generate a minimum of 54% of the country's total electricity, and energy regulation would have been shifted from independent bodies to state regulators, paralleling concerns raised when a Calgary retailer opposed a market overhaul over regulatory impacts.

The contentious proposals faced much criticism from business groups and the United States, Mexico's top trade partner as well as other allies who argued it would violate the regional trade deal, the United States-Mexico-Canada Agreement (USMCA), even as the USA looks to Canada for green power to deepen cross-border energy ties.

Lopez Obrador had argued the bill would have protected consumers and made the country more energy independent, echoing how Texas weighs market reforms to avoid blackouts to bolster reliability, saying the legislation was vital to his plans to "transform" Mexico.

Although the odds were against his party, he came into the vote seeking to leverage his victory in last weekend's referendum on his leadership.

Speaking ahead of the vote, Jorge Alvarez Maynez, a lawmaker from the opposition Citizens' Movement party, said the proposals, if enacted, would damage Mexico, pointing to experiences like the Texas electricity market bailout after a severe winter storm as cautionary examples.

"There isn't a specialist, academic, environmentalist or activist with a smidgen of doubt - this bill would increase electricity prices, slow the transition to (clean) energy in our country and violate international agreements," he added.

Supporters of clean-energy goals noted that subnational shifts, such as the New Mexico 100% clean electricity bill can illustrate alternative pathways to reform.

The bill also contained a provision to nationalize lithium resources.

Lopez Obrador said this week that if the bill was defeated, he would send another bill to Congress on Monday aiming to have at least the lithium portion of the proposed legislation passed.

✅ Cuts methane and greenhouse gas emissions significantly

In a significant environmental initiative, the Southeastern Chester County Refuse Authority (SECCRA) has partnered with French energy company Waga Energy to convert methane emissions from its landfill into renewable natural gas (RNG). This collaboration aims to reduce greenhouse gas emissions and provide sustainable energy to the local community, echoing energy efficiency projects in Quebec seen elsewhere.

Understanding the Issue

Landfills are a substantial source of methane emissions, accounting for over 14% of human-induced methane emissions, according to the U.S. Environmental Protection Agency. Methane is a potent greenhouse gas, and issues like SF6 in power equipment further boost warming, trapping more heat in the atmosphere than carbon dioxide, making its reduction crucial in the fight against climate change.

The SECCRA-Waga Energy Partnership

SECCRA, serving approximately 105,000 residents in Chester County, processes between 450 to 500 tons of waste daily. To mitigate methane emissions from its landfill, SECCRA has partnered with Waga Energy to install a WAGABOX unit—a technology designed to capture and convert landfill methane into RNG, while related efforts like electrified LNG in B.C. illustrate sector-wide decarbonization.

How the WAGABOX Technology Works

The WAGABOX system utilizes a proprietary process to extract methane from landfill gas, purify it, and inject it into the natural gas grid. This process not only reduces harmful emissions, as emerging carbon dioxide electricity generation concepts also aim to do, but also produces a renewable energy source that can be used to heat homes and power businesses.

Environmental and Community Benefits

By converting methane into RNG, the project significantly lowers greenhouse gas emissions, supported by DOE funding for carbon capture initiatives, contributing to climate change mitigation. Additionally, the RNG produced is expected to supply energy to heat over 4,000 homes, providing a sustainable energy source for the local community.

Broader Implications

This initiative aligns with international clean energy cooperation to reduce methane emissions from landfills. Similar projects have been implemented worldwide, demonstrating the effectiveness of converting landfill methane into renewable energy. For instance, Waga Energy has successfully deployed WAGABOX units at various landfills, showcasing the scalability and impact of this technology.

The collaboration between SECCRA and Waga Energy represents a proactive step toward environmental sustainability and energy innovation. By transforming landfill methane into renewable natural gas, the project not only addresses a significant source of greenhouse gas emissions as new EPA power plant rules on carbon capture advance parallel strategies, but also provides a clean energy alternative for the Chester County community.
