The Knoxville Convention Center is going green.

The downtown facility will be installing the first of two solar panel systems on its roof to generate renewable energy for the area. An inverter power pack and chiller for the 30 kilowatt solar panel system will be lowered by helicopter onto the roof.

Convention Center spokesman Jason Bourgoyne said the solar power system will be tied into the TVA-KUB power network and also will meet part of the Convention Center's electricity needs.

The building, which cost $93 million to construct, houses a 30,000-square-foot ballroom that can seat 1,900 people, 120,000 square feet of exhibit space, 13 meeting rooms and a 460-seat lecture hall. It opened in 2002.

Why Atomic Energy Is Heating Up Again

Nuclear Power Revival drives decarbonization, climate change mitigation, and energy security with SMRs, Generation IV designs, baseload reliability, and policy support, complementing renewables to meet net-zero targets and growing global electricity demand.

 

Key Points

A global shift back to nuclear energy, leveraging SMRs and advanced reactors to cut emissions and enhance energy security.

✅ SMRs offer safer, modular, and cost-effective deployment.

✅ Provides baseload power to complement intermittent renewables.

✅ Policy support and investments accelerate advanced designs.

 

In recent years, nuclear power has experienced a remarkable revival in public interest, policy discussions, and energy investment. Once overshadowed by controversies surrounding safety, waste management, and high costs, nuclear energy is now being reexamined as a vital component of the global energy transition, despite recurring questions such as whether it is in decline from some commentators. Here's why nuclear power is "so hot" right now:

1. Climate Change Urgency

One of the most compelling reasons for the renewed interest in nuclear energy is the urgent need to address climate change. Unlike fossil fuels, nuclear power generates electricity with zero greenhouse gas emissions during operation. As countries rush to meet net-zero carbon targets, evidence that net-zero may require nuclear is gaining traction, and nuclear offers a reliable, large-scale alternative to complement renewable energy sources like wind and solar.

2. Energy Security and Independence

Geopolitical tensions and supply chain disruptions have exposed vulnerabilities in relying on imported fossil fuels, and Europe's shrinking nuclear capacity has sharpened concerns over resilience. Nuclear power provides a domestic, stable energy source that can operate independently of volatile global markets. For many nations, this has become a strategic priority, reducing dependence on politically sensitive energy imports.

3. Advances in Technology

Modern innovations in nuclear technology are transforming the industry. Small Modular Reactors (SMRs) are leading the way as part of next-gen nuclear innovation, offering safer, more affordable, and flexible options for nuclear deployment. Unlike traditional large-scale reactors, SMRs can be built faster, scaled to specific energy needs, and deployed in remote or smaller markets.

Additionally, advances in reactor designs, such as Generation IV reactors and fusion research, promise to address longstanding concerns like waste management and safety. For example, some new designs can recycle spent fuel or run on alternative fuels, significantly reducing radioactive waste.

4. Public Perception Is Shifting

Public opinion on nuclear power is also changing. While the industry faced backlash after high-profile incidents like Chernobyl and Fukushima, increasing awareness of climate change and energy security is prompting many to reconsider, including renewed debates such as Germany's potential nuclear return in policy circles. A younger, climate-conscious generation views nuclear energy not as a relic of the past, but as an essential tool for a sustainable future.

5. Renewables Alone Are Not Enough

While renewable energy sources like solar and wind have grown exponentially, their intermittent nature remains a challenge. Energy storage technologies, such as batteries, have not yet matured enough to fully bridge the gap. Nuclear power, with its ability to provide constant, "baseload" energy, as France's fleet demonstrates in practice, serves as an ideal complement to variable renewables in a decarbonized energy mix.

6. Government Support and Investment

Policymakers are taking action to bolster the nuclear sector. Many countries are including nuclear energy in their clean energy plans, offering subsidies, grants, and streamlined regulations to accelerate its deployment. For instance, the United States has allocated billions of dollars to support advanced nuclear projects, the UK's green industrial revolution outlines support for upcoming reactor waves, while Europe has classified nuclear power as "sustainable" under its green taxonomy.

7. Global Energy Demand Is Growing

As populations and economies grow, so does the demand for electricity. Developing nations, in particular, are seeking energy solutions that can support industrialization while limiting environmental impact. Nuclear energy is being embraced as a way to meet these dual objectives, especially in regions with limited access to consistent renewable energy resources.

Challenges Ahead

Despite its potential, nuclear energy is not without its challenges. High upfront costs, lengthy construction timelines, and public concerns over safety and waste remain significant hurdles. The industry will need to address these issues while continuing to innovate and build public trust.

Nuclear power's resurgence is driven by its unique ability to tackle some of the most pressing challenges of our time: climate change, energy security, and the growing demand for electricity. With advances in technology, changing perceptions, and robust policy support, nuclear energy is poised to play a critical role in the global transition to a sustainable and secure energy future.

In a world increasingly shaped by the need for clean and reliable power, nuclear energy has once again become a hot topic—and for good reason.

840 million people have no electricity – World Bank must fund more energy projects

World Bank Energy Policy debates financing for coal, oil, gas, and renewables to fight energy poverty, expand grid reliability, ensure baseload power, and balance climate goals with development finance for affordable, reliable electricity access.

 

Key Points

It outlines the bank's stance on financing fossil fuels and renewables to expand affordable, reliable electricity.

✅ Focus on energy access, baseload reliability, and poverty alleviation

✅ Debate over coal, gas, and renewables in development finance

✅ Geopolitics: China and Russia fill funding gaps, raising risks

 

Why isn’t the World Bank using all available energy resources in its global efforts to fight poverty? That’s the question I’ve asked World Bank President David Malpass. Nearly two years ago, the multilateral development bank decided to stop supporting critical coal, oil and gas projects that help people in developing countries escape poverty.

Along with 11 other senators, and as a member who votes on whether to give U.S. taxpayer dollars to the World Bank, I am pressing the bank to lift these restrictions. Developing countries desperately need access to a steady supply of affordable, reliable clean electricity to support economic growth.

The World Bank has pulled funding for critical electricity projects in poor countries, including high-efficiency power stations that are fueled by coal, even as efforts to revitalize coal communities with clean energy have grown.

Despite Kosovo having the world’s fifth-largest reserves of coal, the bank announced it would only support new energy projects from renewable sources going forward. Kosovo’s Minister of Economic Development Valdrin Lluka responded: “We don’t have the luxury to do such experiments in a poor country such as Kosovo. … It is in our national security interest to secure base energy inside our country.”

The World Bank’s misguided move comes as 840 million people worldwide are living without electricity, including 70 percent of sub-Saharan Africa, and as the fall in global energy investment may lead to shortages.

Even more troubling, nearly 3 billion people in developing countries rely on fuels like wood and other biomass for cooking and home heating, resulting in serious health problems and premature deaths, and the pandemic saw widespread electricity shut-offs that deepened energy insecurity. In 2016, household smoke killed an estimated 2.6 million people.

The World Bank’s mission is to lift people out of poverty. The bank is now compromising that mission in favor of a political agenda targeting certain energy sources.

With the World Bank blocking financing to affordable and reliable energy projects, Russia and China are stepping up their investments in order to gain geopolitical leverage.

President Vladimir Putin is pursuing Russian oil and gas projects in Mozambique, Gabon, and Angola. China’s Belt and Road Initiative is supporting traditional energy resources, with 36 percent of its power projects from 2014 to 2017 involving coal. South Africa had to turn to the China Development Bank to fund its $1.5 billion coal-fired power plant.

There are real risks for countries partnering with China and Russia on these projects. Developing countries are facing what some are calling China’s “debt trap” diplomacy. These nations have also raised concerns over safety compliance, unfair business practices, and labor standards.

As the bank’s largest contributor, the United States has a duty to make sure U.S. taxpayer dollars are used wisely and effectively. Every U.S. dollar at the World Bank should make a difference for people in the developing world.

My colleagues and I have asked the bank to pursue an all-of-the-above energy strategy as it strives to achieve its mission to end extreme poverty and promote shared prosperity. We will take the bank’s response into account during the congressional appropriations process.

The United States is a top global energy producer. And yet Democrats running for president are pursuing anti-energy policies that would hurt not only the United States but the entire world, with implications for U.S. national security as well.

Utilizing our abundant energy resources has fueled an American energy renaissance and a booming U.S. economy, even as disruptions in coal and nuclear have strained the grid, with millions of new jobs and higher wages.

People who are struggling to survive and thrive in developing countries deserve the same opportunity to access affordable and reliable sources of power.

As Microsoft founder and global philanthropist Bill Gates has noted of renewables: "Many people experiencing energy poverty live in areas without access to the kind of grids that are needed to make those technologies cheap and reliable enough to replace fossil fuels."

Ultimately, there is a role for all sources of energy to help countries alleviate poverty and improve the education, health and wellbeing of their people.

The solution to ending energy poverty does not lie in limiting options, but in using all available options. The World Bank must recommit to ending extreme poverty by helping countries use all of the world’s abundant energy resources. Let’s end energy poverty now.

UK breaks coal free energy record again but renewables still need more support

UK Coal-Free Grid Streak highlights record hours without coal, as renewable energy, wind and solar boost electricity generation, cutting CO2 emissions, reducing fossil fuel reliance, and accelerating grid decarbonization amid volatile gas markets.

 

Key Points

It is the UKs longest coal-free power run, driven by renewables, signaling decarbonization and reduced gas reliance.

✅ Record-breaking hours of electricity with zero coal generation

✅ Enabled by wind, solar, and growing offshore wind capacity

✅ Highlights need to cut gas use and expand renewable investment

 

Today is the fourth the UK has entered with not a watt of electricity generated by coal.

It’s the longest such streak since the 1880s and comes only days after the last modern era coal-free power record of 55 hours was set.

That represents good news for those of us who have children and would rather like there to be a planet for them to live on when we’re gone.

Coal generated power is dirty power, and not just through the carbon that gets pumped into the atmosphere when it burns.

The fact that the UK is increasingly able to call upon cleaner alternatives for its requirements, to the extent that records are being regularly broken and coal's share has fallen to record lows, is a welcome development.

The trouble is one of those alternatives is gas, and while it is better than coal it still throws off CO2, among other pollutants. The UK’s use of it, for electricity generation and most of its heating, comes with the added disadvantage of leaving it in hock to volatile international markets and producers that aren’t always friendly.

It was only last month, with the country in the middle of a cold snap, that the Grid was issuing a deficit warning (its first in eight years).

As I wrote at the time, we need to burn less of the stuff as low-carbon progress stalled in 2019 shows, too.

As such, Greenpeace’s call for more investment in renewable energy technology and generation, including solar, onshore wind and offshore wind, which is making an increasing contribution as wind beat coal in 2016 demonstrated, was well made.

Those who complain about onshore wind farms, particularly when they are built in windy places that are pretty, seem willfully blind to the pollution caused by gas.

The need to be listened to less. So do those, like British Gas owner Centrica, that bellyache about green taxes.

It bears repeating that fossil fuels are subsidised still more. It’s just that the subsidies are typically hidden.

A report issued last year by a coalition of environmental organisations found the UK provided $972m (£695m) of annual financing for fossil fuels on average between 2013 and 2015, compared with $172m for renewable energy.

But while they come up with wildly varying amounts as a result of wildly varying approaches, the OECD, the IMF and the International Energy Agency have all quantified substantial subsidies for fossils fuels. Their annual estimates have ranged from $160bn to $5.3tn (yes you read that rate and the number was the IMF’s) globally.

So by all means celebrate coal free days, and a full week without coal power as milestones. But we need more of them more quickly and we need more renewable energy to pick up the slack. As such, the philosophy and approach of government needs to change.

Costa Rica hits record electricity generation from 99% renewable sources

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

 

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

 

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.

Shopping for electricity is getting cheaper in Texas

Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.

 

Key Points

Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.

✅ Deregulated areas saw 17.4% residential price declines since 2006

✅ Regulated zones experienced a 5.5% increase over the same period

✅ Competitive shopping narrowed the gap; Texas averaged below US

 

Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.

About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.

The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.

Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.

Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.

“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”

The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.

Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.

New Hampshire rejects Quebec-Massachusetts transmission proposal

Northern Pass Project faces rejection by New Hampshire regulators, halting Hydro-Quebec clean energy transmission lines to Massachusetts; Eversource vows appeal as the Site Evaluation Committee cites development concerns and alternative routes through Vermont and Maine.

 

Key Points

A project to transmit Hydro-Quebec power to Massachusetts via New Hampshire, recently rejected by state regulators.

✅ New Hampshire SEC denied the transmission application

✅ Up to 9.45 TWh yearly from Hydro-Quebec to Massachusetts

✅ Eversource plans appeal; alternative routes via Vermont, Maine

 

Regulators in the state of New Hampshire on Thursday rejected a major electricity project being piloted by Quebec’s hydro utility and its American partner, Eversource.

Members of New Hampshire’s Site Evaluation Committee unanimously denied an application for the Northern Pass project a week after the state of Massachusetts green-lit the proposal.

Both states had to accept the project, as the transmission lines were to bring up to 9.45 terawatt hours of electricity per year from Quebec’s hydroelectric plants to Massachusetts as part of Hydro-Quebec’s export bid to New England, through New Hampshire.

The 20-year proposal was to be the biggest export contract in Hydro-Quebec’s history, in a region where Connecticut is leading a market overhaul that could affect pricing, and would generate up to $500 million in annual revenues for the provincial utility.

Hydro-Quebec’s U.S. partner, Eversource, said in a new release it was “shocked and outraged” by the New Hampshire regulators’ decision and suggested it would appeal.

“This decision sends a chilling message to any energy project contemplating development in the Granite State,” said Eversource. “We will be seeking reconsideration of the SEC’s decision, as well as reviewing all options for moving this critical clean energy project forward, including lessons from electricity corridor construction in Maine.”

The New Hampshire Union Leader reported Thursday the seven members of the evaluation committee said the project’s promoters couldn’t demonstrate the proposed energy transport lines wouldn’t interfere with the region’s orderly development.

Hydro-Quebec spokesman Serge Abergel said the decision wasn’t great news but it didn’t put a end to the negotiations between the company and the state of Massachusetts.

The hydro utility had proposed alternatives routes through Vermont and Maine amid a 145-mile transmission line debate over the corridor should the original plan fall through.

“There is a provision included in the process in the advent of an impasse, which allows Massachusetts to go back and choose the next candidate on the list,” Abergel said in an interview. “There are still cards left on the table.”
