The Maryland Department of the Environment (MDE) has extended a comment period for new combustion byproduct regulations to February 26.

MDE has proposed regulations to control the disposal of coal combustion byproducts (CCBs) and the use of CCBs in mine reclamation. No federal program exists to regulate the management of these materials. MDE is proceeding in the absence of federal requirements to protect public health and the environment.

CCBs include fly ash, bottom ash, scrubber sludge and other byproducts generated by coal combustion.

Coal combustion facilities in Maryland produce about 2 million tons of coal ash annually. This rate of generation is expected to continue, according to MDE. Scrubber sludge to be generated by flue gas desulphurization pollution control technology is expected to be produced at a rate of about 2.5 million tons annually.

The Environmental Protection Agency has been working on regulations to control the management of coal combustion byproducts since 2000.

Energy companies that burn coal to generate electricity generate CCBs. Also, one major manufacturer in Maryland operates its own power plant using coal to generate electricity for its own needs.

Biden's Announcement of a 100% Tariff on Chinese-Made Electric Vehicles

U.S. 100% Tariff on Chinese EVs aims to protect domestic manufacturing, counter subsidies, and reshape the EV market, but could raise prices, disrupt supply chains, invite retaliation, and complicate climate policy and trade relations.

 

Key Points

A 100% import duty on Chinese EVs to boost U.S. manufacturing, counter subsidies, and address supply chain risks.

✅ Protects domestic EV manufacturing and jobs

✅ Counters alleged subsidies and IP concerns

✅ May raise prices, limit choice, trigger retaliation

 

President Joe Biden's administration recently made headlines with its announcement of a 100% tariff on Chinese electric vehicles (EVs), marking a significant escalation in trade tensions between the two economic powerhouses. The decision, framed as a measure to protect American industries and promote domestic manufacturing, has sparked debates over its potential impact on the EV market, global supply chains, and bilateral relations between the United States and China.

The imposition of a 100% tariff on Chinese-made EVs reflects the Biden administration's broader efforts to revitalize the American automotive industry and promote the transition to electric vehicles as part of its climate agenda and tighter EPA emissions rules that could accelerate adoption. By imposing tariffs on imported EVs, particularly those from China, the administration aims to incentivize domestic production and create jobs in the growing green economy, and to secure critical EV metals through allied supply efforts. Additionally, the tariff is seen as a response to concerns about unfair trade practices, including intellectual property theft and market distortions, allegedly perpetuated by Chinese companies.

However, the announcement has triggered a range of reactions from various stakeholders, with both proponents and critics offering contrasting perspectives on the potential consequences of such a policy. Proponents argue that the tariff will help level the playing field for American automakers, who face stiff competition from Chinese companies benefiting from government subsidies and lower production costs. They contend that promoting domestic manufacturing of EVs will not only create high-quality jobs but also enhance national security by reducing dependence on foreign supply chains at a time when an EV inflection point is approaching.

On the other hand, critics warn that the 100% tariff on Chinese-made EVs could have unintended consequences, including higher prices for consumers, as seen in the UK EV prices and Brexit debate, disruptions to global supply chains, and retaliatory measures from China. Chinese EV manufacturers, such as NIO, BYD, and XPeng, have been gaining momentum in the global market, offering competitive products at relatively affordable prices. The tariff could limit consumer choice at a time when U.S. EV market share dipped in Q1 2024, potentially slowing the adoption of electric vehicles and undermining efforts to combat climate change and reduce greenhouse gas emissions.

Moreover, the tariff announcement comes at a sensitive time for U.S.-China relations, which have been strained by various issues, including trade disputes, human rights concerns, and geopolitical tensions. The imposition of tariffs on Chinese-made EVs could further exacerbate bilateral tensions, potentially leading to retaliatory measures from China and escalating trade frictions. As the world's two largest economies, the United States and China have significant economic interdependencies, and any escalation in trade tensions could have far-reaching implications for global trade and economic stability.

In response to the Biden administration's announcement, Chinese officials have expressed concerns and called for dialogue to resolve trade disputes through negotiation and mutual cooperation. China has also emphasized its commitment to fair trade practices and compliance with international rules and regulations governing trade.

Moving forward, the Biden administration faces the challenge of balancing its domestic priorities with the need to maintain constructive engagement with China and other trading partners, even as EV charging networks scale under its electrification push. While promoting domestic manufacturing and protecting American industries are legitimate policy goals, achieving them without disrupting global trade and undermining diplomatic relations requires careful deliberation and strategic foresight.

In conclusion, President Biden's announcement of a 100% tariff on Chinese-made electric vehicles reflects his administration's commitment to revitalizing American industries and promoting domestic manufacturing. However, the decision has raised concerns about its potential impact on the EV market, global supply chains, and U.S.-China relations. As policymakers navigate these complexities, finding a balance between protecting domestic interests and fostering international cooperation will be crucial to achieving sustainable economic growth and addressing global challenges such as climate change.

Solar + Wind = 10% of US Electricity Generation in 1st Half of 2018

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.

Jump into the numbers below and let us know if you have any more thoughts.

Texas Weighs Electricity Market Reforms To Avoid Blackouts

Texas PUC Electricity Market Reforms aim to boost grid reliability, support ERCOT resilience, pay standby generators, require capacity procurement, and mitigate blackout risk, though analysts warn higher consumer bills and winter reserve margin deficits.

 

Key Points

PUC proposals to bolster ERCOT reliability via standby capacity, capacity procurement, and measures to reduce blackout risk.

✅ Pays generators for standby capacity during grid stress

✅ Requires capacity procurement to meet forecast demand

✅ Could raise consumer bills despite reliability gains

 

The Public Utility Commission of Texas is discussing major reforms to the state’s electricity market with the purpose to avoid a repeat of the power failures and blackouts during the February 2021 winter storm, which led to the death of more than 100 people and left over 11 million residents without electricity for days.

The regulator is discussing at a meeting on Thursday around a dozen proposals to make the grid more stable and reliable in case of emergencies. Proposals include paying power generators that are on standby when the grid needs backup, and requiring companies to pre-emptively buy capacity to meet future demand.

It is not clear yet how many and which of the proposals for electricity market reforms PUC will endorse today, while Texans vote on funding to modernize electricity generation later this year.

Analysts and consumer protection bodies warn that the measures will raise the energy bills for consumers, as some electricity market bailout ideas shift costs to ratepayers as well.

“Customers will be paying for more, but will they be getting more reliability?” Michael Jewell, an attorney with Jewell & Associates PLLC who represents clients at PUC proceedings, told Bloomberg.

“This is going to take us further down a path that’s going to increase cost to consumers, we better be darn sure these are the right choices,” Tim Morstad, Associate State Director, AARP Texas, told FOX 4 NEWS.

Last month, a report by the North American Electric Reliability Corp warned that the Texas power grid remained vulnerable to blackouts in case of a repeat of this year’s February Freeze.

Beyond Texas, electricity blackout risks have been identified across the U.S., underscoring the stakes for grid planning.

According to the 2021-2022 Winter Reliability Assessment report, Texas risks a 37-percent reserve margin deficit in case of a harsh winter, with ERCOT moving to procure capacity to address winter concerns, NERC said.

A reserve margin is the reserve of power generation capacity comparative to demand. The expected reserve margin for Texas for this winter, according to NERC, is 41.9 percent. Yet if another cold spell hits the state, it would affect this spare capacity, pushing the margin deeply into negative territory.

The UK’s energy plan is all very well but it ignores the forecast rise in global sea-levels

UK Marine Energy and Climate Resilience can counter sea level rise and storm surge with tidal power, subsea turbines, heat pumps, and flood barriers, delivering renewable electricity, stability, and coastal protection for the United Kingdom.

 

Key Points

Integrated use of tidal power, barriers, and heat pumps to curb sea level rise, manage storms, and green the UK grid.

✅ Tidal bridges and subsea turbines enhance baseload renewables

✅ Integrated barriers cut storm surge and river flood risk

✅ Heat pumps and marine heat networks decarbonize coastal cities

 

IN concentrating on electrically driven cars, the UK’s new ten-point energy plans, and recent UK net zero policies, ignores the elephant in the room.

It fails to address the forecast six-metre sea level rise from global warming rapidly melting the Greenland ice sheet.

Rising sea levels and storm surge, combined with increasingly heavy rainfall swelling our rivers, threaten not only hundreds of coastal communities but also much unprotected strategic infrastructure, including electricity systems that need greater resilience.

New nuclear power stations proposed in this United Kingdom plan would produce radioactive waste requiring thousands of years to safely decay.

This is hardly the solution for the Green Energy future, or the broader global energy transition, that our overlooked marine energy resource could provide.

Sea defences and barrier design, built and integrated with subsea turbines and heat pumps, can deliver marine-driven heat and power to offset the costs, not only of new Thames Barriers, but also future Severn, Forth and other barrages, while reducing reliance on high-GWP gases such as SF6 in switchgear across the grid.

At the Pentland Firth, existing marine turbine power could be enhanced by turbines deployed from new tidal bridges to provide much of UK’s electricity needs, as nations chart an electricity future that replaces fossil fuels, from its estimated 60 gigawatt capability.

Energy from Bluemull Sound could likewise be harvested and exported or used to enhance development around UK’s new space station at Unst.

The 2021 Climate Change Summit gives Glasgow the platform to secure Scotland’s place in a true green, marine energy future and help build an electric planet for the long term.

We must not waste this opportunity.

THERE is no vaccine for climate change.

It is, of course, wonderful news that such progress is being made in the development of Covid-19 vaccines but there is a risk that, no matter how serious the Covid crisis is, it is distracting attention, political will and resources from the climate crisis, a much longer term and more devastating catastrophe.

They are intertwined. As climate and ecological systems change, vectors and pathogens migrate and disease spreads.

What lessons can be learned from one to apply to the other?

Prevention is better than cure. We need to urgently address the climate crisis, charting a path to net zero electricity by the middle of the century, to help prevent future pandemics.

We are only as safe as the most vulnerable. Covid immunisation will protect the most vulnerable; to protect against the effects of climate change we need to look far more deeply. Global challenges require systemic change.

Neither Covid or climate change respect national borders and, for both, we need to value and trust science and the scientific experts and separate them from political posturing.

US looks to decommission Alaskan military reactor

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

 

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

 

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

#google#

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."
