U.S. President Barack Obama pushed for more investment in solar and wind energy, saying the country that can make renewable energy sources price-competitive with traditional fossil fuels will become the economic superpower of the future.

Obama, speaking at a townhall meeting in Elkhart, Indiana, said renewable energy companies needed tax breaks and loan guarantees to provide incentives for firms to manufacture and customers to purchase solar and wind energy.

Obama acknowledged that while the cost of producing electricity by wind and solar has declined, it is still cheaper to generate power from plants fueled by coal or natural gas.

However, Obama said he wanted the government to invest every year in new technologies to drive down renewable energy costs over the long term.

"The country that figures out how to make cheaper energy that's also clean, that country is going to win the economic competition of the future," he said.

The roughly $800 billion stimulus package pending in Congress to revive the American economy includes billions of dollars in tax breaks and other financial incentives to boost the use of renewable energy.

They are intended to ensure solar and wind energy companies have steady business.

Obama called on Congress to require U.S. utilities to generate a certain amount of their electricity supplies, such as 15 to 20 percent, from renewable energy sources.

He said that, once such a benchmark is set, then renewable energy companies can "count on a pretty solid market that they're going to be able to sell their energy to."

The Senate Energy and Natural Resources Committee held a hearing on draft legislation that would set a national renewable energy standard.

Under the bill, the amount of the U.S. electricity supply coming from renewable energy resources would gradually increase to 4 percent by 2012, 8 percent by 2015, 12 percent by 2018, 16 percent by 2020 and 20 percent by 2039.

Obama also pledged to double U.S. renewable energy production within the next three years.

Energy-hungry Europe to brighten profit at US solar equipment makers

European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.

 

Key Points

Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.

✅ Germany leads EU rooftop PV installations

✅ Enphase and SolarEdge see revenue growth

✅ High gas prices and policies spur adoption

 

Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.

The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.

Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.

The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.

As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.

About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.

Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.

SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.

In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.

Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.

Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.

Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.

Energy groups warn Trump and Perry are rushing major change to electricity pricing

DOE Grid Resilience Pricing Rule faces FERC review as energy groups challenge an expedited timeline to reward coal and nuclear for reliability in wholesale markets, impacting natural gas, renewables, baseload economics, and grid pricing.

 

Key Points

A DOE proposal directing FERC to compensate coal and nuclear plants for reliability attributes in wholesale markets.

✅ Industry coalition seeks normal FERC timeline and review

✅ Impacts wholesale pricing, baseload economics, reliability

✅ Request for 90-day comments and reply period

 

A coalition of 11 industry groups is pushing back on Energy Secretary Rick Perry's efforts to quickly implement a major change to the way electric power is priced in the United States.

The Energy Department on Friday proposed a rule that stands to bolster coal and nuclear power plants by forcing the regional markets that set electricity prices to compensate them for the reliability they provide. Perry asked the Federal Energy Regulatory Commission to consider and finalize the rule within 60 days, including a 45-day period during which stakeholders can issue comments.

On Monday, groups representing petroleum, natural gas, electric power and renewable energy interests including ACORE urged FERC to reject the expedited process, as well as the Department of Energy's request that the regulatory commission consider putting in place an interim rule.

They say the time frame is "aggressive" and the department didn't provide adequate justification for fast-tracking a process that could have huge impacts on wholesale electricity markets.

"This is one of the most significant proposed rules in decades related to the energy industry and, if finalized, would unquestionably have significant ramifications for wholesale markets under the Commission's jurisdiction," the groups said in the motion filed with FERC.

"The Energy Industry Associations urge the Commission to reject the proposed unreasonable timelines and instead proceed in a manner that would afford meaningful consideration of public comments and be consistent with the normal deliberative process that it typically affords such major undertakings," they said.

The groups are requesting a 90-day comment period, as well as another period for reply comments. FERC, which has authority to regulate interstate transmission and sale of electricity and natural gas, is not required to decide in favor of the rule but, amid a recent FERC decision that drew industry criticism, must consider it.

Expediting the process or imposing an interim rule is generally limited to emergencies, the groups said. The Energy Department's letter to FERC does not even attempt to establish that an immediate threat to U.S. electricity reliability exists, they allege.

 

  • A coalition of energy industry groups asked regulators to reject a rule proposed by the U.S. Department of Energy on Friday.
  • The rule would bolster coal-fired and nuclear power plants by requiring wholesale markets to compensate them for certain attributes.
  • The groups say the Energy Department proposed "unreasonable timelines" for stakeholders to offer feedback on a rule with "significant ramifications for wholesale markets."

 

The groups cite a recent Energy Department report on grid reliability that concluded: "reliability is adequate today despite the retirement of 11 percent of the generating capacity available in 2002, as significant additions from natural gas, wind, and solar have come online since then."

The Department of Energy did not return a request for comment.

The Energy Department's rule marks a flashpoint in the battle between natural gas-fired and renewable energy and so-called baseload power sources like coal and nuclear.

Separately, coal and business groups have supported the EPA in litigation over the Affordable Clean Energy rule, as documented in legal challenges brought during the rule's defense.

Gas, wind and solar power have eaten into coal and nuclear's share of U.S. electric power generation in recent years. That is thanks to a boom in U.S. gas production that has pushed down prices, the rapid adoption of subsidized renewable energy and President Barack Obama's efforts to mitigate emissions from power plants, which the Trump administration has sought to replace with a tune-up as policies shift.

Electric power is priced in deregulated, wholesale markets in many parts of the country. Utilities typically draw on the cheapest power sources first.

Some worry that the retirement of coal-fired and nuclear power plants undermines the nation's ability to reliably and affordably deliver electricity to households and businesses.

President Donald Trump has vowed to revive the ailing coal industry, declaring an end to the 'war on coal' in public remarks. Trump, Perry and other administration officials reject the consensus among climate scientists that carbon emissions from sources like coal-fired plants are the primary cause of global warming.

Why electric buses haven't taken over the world—yet

Electric Buses reduce urban emissions and noise, but require charging infrastructure, grid upgrades, and depot redesigns; they offer lower operating costs and simpler maintenance, with range limits influencing routes, schedules, and on-route fast charging.

 

Key Points

Battery-electric buses cut emissions and noise while lowering operating and maintenance costs for transit agencies.

✅ Lower emissions, noise; improved rider experience

✅ Requires charging, grid upgrades, depot redesigns

✅ Range limits affect routes; on-route fast charging helps

 

In lots of ways, the electric bus feels like a technology whose time has come. Transportation is responsible for about a quarter of global emissions, and those emissions are growing faster than in any other sector. While buses are just a small slice of the worldwide vehicle fleet, they have an outsize effect on the environment. That’s partly because they’re so dirty—one Bogotá bus fleet made up just 5 percent of the city’s total vehicles, but a quarter of its CO2, 40 percent of nitrogen oxide, and more than half of all its particulate matter vehicle emissions. And because buses operate exactly where the people are concentrated, we feel the effects that much more acutely.

Enter the electric bus. Depending on the “cleanliness” of the electric grid into which they’re plugged, e-buses are much better for the environment. They’re also just straight up nicer to be around: less vibration, less noise, zero exhaust. Plus, in the long term, e-buses have lower operating costs, and related efforts like US school bus electrification are gathering pace too.

So it makes sense that global e-bus sales increased by 32 percent last year, according to a report from Bloomberg New Energy Finance, as the age of electric cars accelerates across markets worldwide. “You look across the electrification of cars, trucks—it’s buses that are leading this revolution,” says David Warren, the director of sustainable transportation at bus manufacturer New Flyer.

Today, about 17 percent of the world’s buses are electric—425,000 in total. But 99 percent of them are in China, where a national mandate promotes all sorts of electric vehicles. In North America, a few cities have bought a few electric buses, or at least run limited pilots, to test the concept out, and early deployments like Edmonton's first e-bus offer useful lessons as systems ramp up. California has even mandated that by 2029 all buses purchased by its mass transit agencies be zero-emission.

But given all the benefits of e-buses, why aren’t there more? And why aren’t they everywhere?

“We want to be responsive, we want to be innovative, we want to pilot new technologies and we’re committed to doing so as an agency,” says Becky Collins, the manager of corporate initiative at the Southeastern Pennsylvania Transportation Authority, which is currently on its second e-bus pilot program. “But if the diesel bus was a first-generation car phone, we’re verging on smartphone territory right now. It’s not as simple as just flipping a switch.”

One reason is trepidation about the actual electric vehicle. Some of the major bus manufacturers are still getting over their skis, production-wise. During early tests in places like Belo Horizonte, Brazil, e-buses had trouble getting over steep hills with full passenger loads. Albuquerque, New Mexico, canceled a 15-bus deal with the Chinese manufacturer BYD after finding equipment problems during testing. (The city also sued). Today’s buses get around 225 miles per charge, depending on topography and weather conditions, which means they have to re-up about once a day on a shorter route in a dense city. That’s an issue in a lot of places.

If you want to buy an electric bus, you need to buy into an entire electric bus system. The vehicle is just the start.

The number one thing people seem to forget about electric buses is that they need to get charged, and emerging projects such as a bus depot charging hub illustrate how infrastructure can scale. “We talk to many different organizations that get so fixated on the vehicles,” says Camron Gorguinpour, the global senior manager for the electric vehicles at the World Resources Institute, a research organization, which last month released twin reports on electric bus adoption. “The actual charging stations get lost in the mix.”

But charging stations are expensive—about $50,000 for your standard depot-based one. On-route charging stations, an appealing option for longer bus routes, can be two or three times that. And that’s not even counting construction costs. Or the cost of new land: In densely packed urban centers, movements inside bus depots can be tightly orchestrated to accommodate parking and fueling. New electric bus infrastructure means rethinking limited space, and operators can look to Toronto's TTC e-bus fleet for practical lessons on depot design. And it’s a particular pain when agencies are transitioning between diesel and electric buses. “The big issue is just maintaining two sets of fueling infrastructure,” says Hanjiro Ambrose, a doctoral student at UC Davis who studies transportation technology and policy.

“We talk to many different organizations that get so fixated on the vehicles. The actual charging stations get lost in the mix as the American EV boom gathers pace across sectors.”

Then agencies also have to get the actual electricity to their charging stations. This involves lengthy conversations with utilities about grid upgrades, rethinking how systems are wired, occasionally building new substations, and, sometimes, cutting deals on electric output, since electric truck fleets will also strain power systems in parallel. Because an entirely electrified bus fleet? It’s a lot to charge. Warren, the New Flyer executive, estimates it could take 150 megawatt-hours of electricity to keep a 300-bus depot charged up throughout the day. Your typical American household, by contrast, consumes 7 percent of that—per year. “That’s a lot of work by the utility company,” says Warren.

For cities outside of China—many of them still testing out electric buses and figuring out how they fit into their larger fleets—learning about what it takes to run one is part of the process. This, of course, takes money. It also takes time. Optimists say e-buses are more of a question of when than if. Bloomberg New Energy Finance projects that just under 60 percent of all fleet buses will be electric by 2040, compared to under 40 percent of commercial vans and 30 percent of passenger vehicles.

Which means, of course, that the work has just started. “With new technology, it always feels great when it shows up,” says Ambrose. “You really hope that first mile is beautiful, because the shine will come off. That’s always true.”

EV Sales Still Behind Gas Cars

U.S. EV and Hybrid Sales 2024 show slower adoption versus gas-powered cars, as charging infrastructure gaps, range anxiety, higher upfront costs, and affordability concerns persist despite incentives, battery tech advances, and expanding fast-charging networks.

 

Key Points

They represent 10-15% of U.S. car sales, lagging gas models due to costs, charging gaps, range anxiety, and access.

✅ 10-15% of U.S. auto sales; gas cars dominate

✅ Barriers: upfront cost, limited charging, range anxiety

✅ Incentives, battery tech, and networks may boost adoption

 

Sales of hybrid and electric vehicles (EVs) in the U.S. are continuing to trail behind traditional gas-powered vehicles in 2024, despite significant advancements in automotive technology and growing public awareness of environmental concerns. While the electric vehicle market has seen steady growth and recent sales momentum over the past few years, the gap between EVs and gasoline-powered cars remains wide.

In 2024, hybrid and electric vehicles are projected to account for roughly 10-15% of total car sales in the U.S., a figure that, though significant, still lags far behind the sales of gas-powered vehicles and follows a Q1 2024 EV market share dip in the U.S., according to recent data. Analysts point to several factors contributing to this slower adoption rate, including higher upfront costs, limited charging infrastructure, and consumer concerns over range anxiety. Additionally, while EVs and hybrids offer lower lifetime operating costs, the initial price difference remains a hurdle for many prospective buyers.

One of the key challenges for EV sales continues to be the perception of cost, even as analyses show they can be better for the planet and often your budget over time. While federal and state incentives have made EVs more affordable, especially for lower-income buyers, the price tag for many electric models remains steep, particularly for higher-end vehicles. Even with government rebates, EVs can still be priced higher than their gasoline counterparts, making them less accessible for middle-class consumers. Many potential buyers are also hesitant to make the switch, unsure if the long-term savings will outweigh the initial investment.

Another critical factor is the limited charging infrastructure in many parts of the country. Though major cities have seen significant improvements in charging stations, rural areas and smaller towns still lack the necessary infrastructure to support widespread EV use. This uneven distribution of charging stations leads to concerns about being stranded in areas without access to fast-charging options. While automakers are working on expanding charging networks, the pace of this development is slow, and EVs won't go mainstream until key problems are fixed according to industry leaders.

Range anxiety is also a continuing issue, despite improvements in battery technology. Though newer electric vehicles can go further on a single charge than ever before, the range of many EVs still doesn't meet the expectations of some drivers, particularly those who regularly take long road trips or live in rural areas. The longer charging times and the necessity of planning routes around charging stations add to the hesitation, especially when gasoline-powered vehicles provide greater convenience and flexibility.

The shift toward EVs is further hindered by the continued dominance of gas-powered cars in the market. Gasoline vehicles benefit from decades of development, an extensive fueling infrastructure, and familiarity with the technology. For many consumers, the convenience, affordability, and ease of use of gas-powered vehicles still outweigh the benefits of switching to an electric alternative. Additionally, with fluctuating fuel prices, many drivers continue to find gas-powered cars relatively cost-effective in terms of daily commuting, especially when compared to the current costs of EV ownership.

Despite these challenges, there is hope for a future shift. The federal government’s push for stricter emissions regulations and tax incentives continues to fuel growth in the electric vehicle market. As automakers ramp up production and more affordable options become available, EV sales are expected to increase in the coming years. Companies like Tesla, Ford, whose hybrids are getting a boost, and General Motors are leading the charge, while new manufacturers like Rivian and Lucid Motors are offering alternatives to traditional gasoline vehicles.

Furthermore, the development of new technologies, such as solid-state batteries and faster charging systems, could help alleviate some of the current drawbacks of electric vehicles. If these advancements reach mass-market production in the next few years, they could help make EVs a more attractive and practical option for consumers, aligning with within-a-decade adoption forecasts from some industry observers.

In conclusion, while hybrid and electric vehicles are growing in popularity, gas-powered vehicles continue to dominate the U.S. car market in 2024. Challenges such as high upfront costs, limited charging infrastructure, and concerns about range persist, making it difficult for many consumers to make the switch to electric even as they ask if it's time to buy an EV in 2024. However, with continued investment in technology and infrastructure, the gap between EVs and gas-powered vehicles could narrow in the years to come.

Canada in top 10 for hydropower jobs, but doesn't rank on other renewables

Canada Renewable Energy Jobs rank top 10 in hydropower, says IRENA, but trail in solar PV, wind power, and liquid biofuels; clean tech growth, EV manufacturing, and Canada Infrastructure Bank funding signal broader carbon-neutral opportunities.

 

Key Points

Canada counts 61,130 clean energy roles, top 10 in hydropower, with potential in solar, wind, biofuels, and EV manufacturing.

✅ 61,130 clean energy jobs in Canada per IRENA

✅ Top 10 share in hydropower employment

✅ Growth expected in solar, wind, biofuels, and EVs

 

Canada has made the top 10 list of countries for the number of jobs in hydropower, but didn’t rank in three other key renewable energy technologies, according to new international figures.

Although Canada has only two per cent of the global workforce, it had one of the 10 largest slices of the world’s jobs in hydropower in 2019, says the Abu Dhabi-based International Renewable Energy Agency (IRENA)

Canada didn’t make IRENA’s other top-10 employment lists, for solar photovoltaic (PV) technology, where solar power lags by international standards, liquid biofuels or wind power, released Sept. 30. Figures from the agency show the whole sector represents 61,130 jobs across Canada, or 0.5 per cent of the world’s 11.5 million jobs in renewables.

The numbers show Canada needs to move faster to minimize the climate crisis, including by joining trade blocs that put tariffs on high-carbon goods, argued the Victoria-based BC Sustainable Energy Association after reviewing IRENA’s report. The Canadian Renewable Energy Association also said it showed the country has untapped job creation potential, even as growth projections were scaled back after Ontario scrapped a clean energy program.

But other clean tech advocates say there’s more to the story. When tallying clean energy jobs, it's worth a broader look, Clean Energy Canada argued, pointing to the recent Ford-Unifor deal that includes a $1.8-billion commitment to produce electric vehicles in Oakville, Ont.

Natural Resources Minister Seamus O'Regan’s office also pointed out the renewables employment figures from IRENA are proportional to global population. “While Canada's share of the global clean energy job market is in line with our population size, we produce almost 2.7 per cent of the world’s total primary renewable energy supply. As only 0.5 per cent of the global population, we punch above our weight,” said O'Regan's press secretary, Ian Cameron.

Canada joined IRENA in January 2019 and the country has been described by the association as an “important market” for renewables over the long term.

On Thursday, Prime Minister Justin Trudeau announced a new $10-billion “Growth Plan” to be run by the Canada Infrastructure Bank that would include “$2.5 billion for clean power to support renewable generation and storage and to transmit clean electricity between provinces, territories, and regions, including to northern and Indigenous communities.” The infrastructure bank's plan is expected to create 60,000 jobs, the government said, and in Alberta an Alberta renewables surge could power 4,500 jobs as projects scale up.

World ‘building the renewable energy revolution now’

A powerful renewables sector is not just about job creation. It is also imperative if we are to meet global climate objectives, according to the Intergovernmental Panel on Climate Change. Renewable energy sources have to make up at least a 63 per cent share of the global electricity market by mid-century to battle the more extreme effects of climate change, it said.

“The IRENA report shows that people all over of the world are building the renewable energy revolution now,” said Tom Hackney, policy adviser for the BC Sustainable Energy Association.

“Many people in Canada are doing so, too. But we need to move faster to minimize climate change. For example, at the level of trade policy, a great idea would be to develop low-carbon trading blocs that put tariffs on goods with high embodied carbon emissions.”

Canadian Renewable Energy Association president and CEO Robert Hornung said the IRENA jobs review highlights “significant job creation potential” in Canada. As governments explore how to stimulate economic recovery from the impact of the COVID-19 pandemic, said Hornung, it's important to “capitalize on Canada's untapped renewable energy resources.”

In Canada, 82 per cent of the electricity grid is already non-emitting, noted Sarah Petrevan, policy director for Clean Energy Canada.

With the federal government committing to a 90 per cent non-emitting grid by 2030, said Petrevan, more wind and solar deployment can be expected, even though solar demand has lagged in recent years, especially in the Prairies where renewables are needed to help with Canada’s coal-fired power plant phase out.

One example of renewables in the Prairies, where the provinces are poised to lead growth, is the Travers Solar project, which is expected to be constructed in Alberta through 2021, and is being touted as “Canada's largest solar farm.”

But renewables are only “one part of the broader clean energy sector,” said Petrevan. Clean Energy Canada has outlined how Canada could be electric and clean with the right choices, and has calculated clean tech supports around 300,000 jobs, projected to grow to half a million by 2030.

“We’re talking about a transition of our energy system in every sense — not just in the power we produce. So while the IRENA figures provide global context, they reflect only a portion of both our current reality and the opportunity for Canada,” she said.

The organization’s research has shown that manufacturing of electric vehicles would be one of the fastest-growing job creators over the next decade. Putting a punctuation mark on that is a recent $1.8-billion deal with Ford Motor Company of Canada to produce five models of electric vehicles in Oakville, Ont.

China ‘remains the clear leader’ in renewables jobs

With 4.3 million renewable energy jobs in 2019, or 38 per cent of all renewables jobs, China “remains the clear leader in renewable energy employment worldwide,” the IRENA report states. China has the world's largest population and the second-largest GDP.

The country is also by far the world’s largest emitter of carbon pollution, at 28 per cent of global greenhouse gas emissions, and has significant fossil fuel interests. Chinese President Xi Jinping called for a “green revolution” last month, and pledged to “achieve carbon neutrality before 2060.”

China holds the largest proportion of jobs in hydropower, with 29 per cent of all jobs, followed by India at 19 per cent, Brazil at 11 per cent and Pakistan at five per cent, said IRENA.

Canada, with 32,359 jobs in the industry, and Turkey and Colombia hold two per cent each of the world’s hydropower jobs, while Myanmar and Russia hold three per cent each and Vietnam has four per cent.

China also dominates the global solar PV workforce, with 59 per cent of all jobs, followed by Japan, the United States, India, Bangladesh, Vietnam, Malaysia, Brazil, Germany and the Philippines. There are 4,261 jobs in solar PV in Canada, IRENA calculated, and the country is set to hit a 5 GW solar milestone as capacity expands, out of a global workforce of 3.8 million jobs.

In wind power, China again leads, with 44 per cent of all jobs. Germany, the United States and India come after, with the United Kingdom, Denmark, Mexico, Spain, the Philippines and Brazil following suit. Canada has 6,527 jobs in wind power out of 1.17 million worldwide.

As for liquid biofuels, Brazil leads that industry, with 34 per cent of all jobs. Indonesia, the United States, Colombia, Thailand, Malaysia, China, Poland, Romania and the Philippines fill out the top 10. There are 17,691 jobs in Canada in liquid biofuels.

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.
