Some consumers are starting to switch their regular household halogen or incandescent light bulbs to LED (light-emitting diode) technology. Up until now, LEDs have typically been used more in professional applications, but they are beginning to increase in popularity as a household lighting solution.

Homeowners can enjoy many benefits by using LEDs. The light bulbs are long-lasting and provide consistent, high-quality light output. Also, the bulbs use considerably less electricity than other types of bulbs so a home can be lit tastefully for a fraction of the cost.

"Consumers have told us that they've been disappointed with many LED bulbs to date, because of the poor quality," says Yong Cai, product manager for Philips Lighting Canada. Philips on the other hand, only offers the highest quality LED bulbs, exceeding consumer's expectations because they are so easy to use and last so long.

It can be difficult to know how to choose the right replacement LED bulb. Right now, one very popular use is to replace a 35 watt halogen light bulb in a lamp or overhead pot light fixture with a 6 watt LED bulb, like the AmbientGU10 from Philips. Your lighting retailer will be able to give you additional options for the replacement of other bulbs in your home.

Frustration Mounts as Houston's Power Outage Extends

Houston Power Outage Heatwave intensifies a prolonged blackout, straining the grid and infrastructure resilience; emergency response, cooling centers, and power restoration efforts race to protect vulnerable residents amid extreme temperatures and climate risks.

 

Key Points

A multi-day blackout and heatwave straining Houston's grid, limiting cooling, and prompting emergency response.

✅ Fourth day without power amid dangerous heat

✅ Grid failures expose infrastructure vulnerabilities

✅ Cooling centers, aid groups support vulnerable residents

 

Houston is enduring significant frustration and hardship as a power outage stretches into its fourth day amid a sweltering heatwave. The extended blackout has exacerbated the challenges faced by residents in one of the nation’s largest and most dynamic cities, underscoring the critical need for reliable infrastructure and effective emergency response systems.

The power outage began early in the week, coinciding with a severe heatwave that has driven temperatures to dangerous levels. With the city experiencing some of the highest temperatures of the year, the lack of electricity has left residents without essential cooling, contributing to widespread discomfort and health risks. The heatwave has placed an added strain on Houston's already overburdened power grid, which has struggled to cope with the soaring demand for air conditioning and cooling.

The prolonged outage has led to escalating frustration among residents. Many households are grappling with sweltering indoor temperatures, leading to uncomfortable living conditions and concerns about the impact on vulnerable populations, including the elderly, young children, and individuals with pre-existing health conditions. The lack of power has also disrupted daily routines, as morning routine disruptions in London demonstrate, including access to refrigeration for food, which has led to spoilage and further complications.

Emergency services and utility companies have been working around the clock to restore power, but progress has been slow, echoing how Texas utilities struggled to restore power during Hurricane Harvey, as crews contended with access constraints. The complexity of the situation, combined with the high demand for repairs and the challenging weather conditions, has made it difficult to address the widespread outages efficiently. As the days pass, the situation has become increasingly dire, with residents growing more impatient and anxious about when they might see a resolution.

Local officials and utility providers have been actively communicating with the public, providing updates on the status of repairs and efforts to restore power. However, the communication has not always been timely or clear, leading to further frustration among those affected. The sense of uncertainty and lack of reliable information has compounded the difficulties faced by residents, who are left to manage the impacts of the outage with limited guidance.

The situation has also raised questions about the resilience of Houston’s power infrastructure. The outage has highlighted vulnerabilities in the city's energy grid, similar to how a recent windstorm caused significant outages elsewhere, which has faced previous challenges but has not experienced an extended failure of this magnitude in recent years. The inability of the grid to withstand the extreme heat and maintain service during a critical time underscores the need for infrastructure improvements and upgrades to better handle similar situations in the future.

In response to the crisis, community organizations and local businesses have stepped up to provide support to those in need, much like Toronto's cleanup after severe flooding mobilized volunteers and services, in order to aid affected residents. Cooling centers have been established to offer relief from the heat, providing a respite for individuals who are struggling to stay cool at home. Additionally, local food banks and charitable organizations are distributing essential supplies to those affected by food spoilage and other challenges caused by the power outage.

The power outage and heatwave have also sparked broader discussions about climate resilience and preparedness. Extreme weather events and prolonged heatwaves are becoming increasingly common due to climate change, as strong winds knocked out power across the Miami Valley recently, raising concerns about how cities and infrastructure systems can adapt to these new realities. The current situation in Houston serves as a stark reminder of the importance of investing in resilient infrastructure and developing comprehensive emergency response plans to mitigate the impacts of such events.

As the outage continues, there is a growing call for improved strategies to manage power grid failures, with examples like the North Seattle outage affecting 13,000 underscoring the need, and better support for residents during crises. Advocates are urging for a reevaluation of emergency response protocols, increased investment in infrastructure upgrades, and enhanced communication systems to ensure that the public receives timely and accurate information during emergencies.

In summary, Houston's power outage, now extending into its fourth day amid extreme heat, has caused significant frustration and hardship for residents. The prolonged disruption has underscored the need for more resilient energy infrastructure, as seen when power outages persisted for hundreds in Toronto, and effective emergency response measures. With temperatures soaring and the situation continuing to unfold, the city faces a critical challenge in restoring power, managing the impacts on its residents, and preparing for future emergencies. The crisis highlights broader issues related to infrastructure resilience and climate adaptation, emphasizing the need for comprehensive strategies to address and mitigate the effects of extreme weather events.

UK's Energy Transition Stalled by Supply Delays

UK Clean Energy Supply Chain Delays are slowing decarbonization as transformer lead times, grid infrastructure bottlenecks, and battery storage contractors raise costs and risk 2030 targets despite manufacturing expansions by Siemens Energy and GE Vernova.

 

Key Points

Labor and equipment bottlenecks delay transformers and grid upgrades, risking the UK's 2030 clean power target.

✅ Transformer lead times doubled or tripled, raising project costs

✅ Grid infrastructure and battery storage contractors in short supply

✅ Firms expand capacity cautiously amid uncertain demand signals

 

The United Kingdom's ambitious plans to transition to clean energy are encountering significant obstacles due to prolonged delays in obtaining essential equipment such as transformers and other electrical components. These supply chain challenges are impeding the nation's progress toward decarbonizing its power sector by 2030, even as wind leads the power mix in key periods.

Supply Chain Challenges

The global surge in demand for renewable energy infrastructure, including large-scale storage solutions, has led to extended lead times for critical components. For example, Statera Energy's storage plant in Thurrock experienced a 16-month delay for transformers from Siemens Energy. Such delays threaten the UK's goal to decarbonize power supplies by 2030.

Economic Implications

These supply chain constraints have doubled or tripled lead times over the past decade, resulting in increased costs and straining the energy transition as wind became the main source of UK electricity in a recent milestone. Despite efforts to expand manufacturing capacity by companies like GE Vernova, Hitachi Energy, and Siemens Energy, the sector remains cautious about overinvesting without predictable demand, and setbacks at Hinkley Point C have reinforced concerns about delivery risks.

Workforce and Manufacturing Capacity

Additionally, there is a limited number of companies capable of constructing and maintaining battery sites, adding to the challenges. These issues underscore the necessity for new factories and a trained workforce to support the electrification plans and meet the 2030 targets.

Government Initiatives

In response to these challenges, the UK government is exploring various strategies to bolster domestic manufacturing capabilities and streamline supply chains while supporting grid reform efforts underway to improve system resilience. Investments in infrastructure and workforce development are being considered to mitigate the impact of global supply chain disruptions and advance the UK's green industrial revolution for next-generation reactors.

The UK's energy transition is at a critical juncture, with supply chain delays posing substantial risks to achieving decarbonization goals, including the planned end of coal power after 142 years for the UK. Addressing these challenges will require coordinated efforts between the government, industry stakeholders, and international partners to ensure a sustainable and timely shift to clean energy.

Power bill cut for 22m Thailand houses

Thailand Covid-19 Electricity Bill Relief offers energy subsidies, tariff cuts, and free power for small meters, helping work-from-home users as authorities waive charges and discount kWh rates via EGAT, MEA, PEA for three months.

 

Key Points

Program waiving or cutting household electricity bills for 22 million homes in March-May, easing work-from-home costs.

? Free power for meters <= 5 amps; up to 10M homes

? Up to 800 kWh: pay February rate; above, 50% discount

? >3,000 kWh: 30% discount; program valid March-May

 

The Thailand cabinet has formally approved energy authorities' decision to either waive or cut electricity charges, similar to B.C. electricity relief measures, for 22 million households where people are working at home because of the coronavirus disease.

Energy Minister Sontirat Sontijirawong said after the cabinet meeting on Tuesday that the ministers acknowledged the step taken by from the Energy Regulatory Commission, the Electricity Generating Authority of Thailand, the Metropolitan Electricity Authority and the Provincial Electricity Authority and noted parallels with Ontario's COVID-19 hydro plan rolled out to support ratepayers.

The measure would be valid for three months, from March to May, and cover 22 million households. It would cost the state 23.68 billion baht in lost revenue, he said, a pattern also seen with Ontario rate reductions affecting provincial revenues.


"The measure reduces the electricity charges burden on households. It is the cost of living of the people who are working from home to support the government's control of Covid-19," Mr Sontirat said.

The business sector also wants similar assistance, echoing sentiments from Ontario manufacturers during recent price reduction efforts. He said their requests were being considered.

Free electricity is extended to households with a power meter of no more than 5 amps. Up to 10 million households are expected to benefit, although issues like electricity payment challenges in India highlight different market contexts.

For households with a power meter over 5 amps, if their consumption does not exceed 800 units (kilowat hours), they will pay as much as they did in their February bill. The amount over 800 units will be subject to a 50 per cent discount, while elsewhere B.C. commercial consumption has fallen sharply.

Large houses that consume more than 3,000 units will get a 30 per cent discount, at a time when BC Hydro demand is down 10%.

Energy storage poised to tackle grid challenges from rising EVs as mobile chargers bring new flexibility

EV Charging Grid Readiness addresses how rising EV adoption, larger batteries, and fast charging affect electric utilities, using vehicle-to-grid, energy storage, mobile and temporary chargers, and smart charging to mitigate distribution stress.

 

Key Points

Planning and tech to manage EV load growth with V2G, storage and smart charging to avoid overloads on distribution grids.

✅ Lithium-ion costs may drop 60%, enabling new charger models

✅ Mobile and temporary chargers buffer local distribution peaks

✅ Smart charging and V2G defer transformer and feeder upgrades

 

The impacts of COVID-19 likely mean flat electric vehicle (EV) sales this year, but a trio of new reports say the long-term outlook is for strong growth — which means the electric grid and especially state power grids will need to respond.

As EV adoption grows, newer vehicles will put greater stress on the electric grid due to their larger batteries and capacity for faster charging, according to Rhombus Energy Solutions, while a DOE lab finds US electricity demand could rise 38% as EV adoption scales. A new white paper from the company predicts the cost of lithium-ion batteries will drop by 60% over the next decade, helping enable a new set of charging solutions.

Meanwhile, mobile and temporary EV charging will grow from 0.5% to 2% of the charging market by 2030, according to new Guidehouse research. The overall charging market is expected to reach reach almost $16 billion in revenues in 2020 and more than $60 billion by 2030. ​A third report finds long-range EVs are growing their share of the market as well, and charging them could cause stress to electric distribution systems. 

"One can expect that the number of EVs in fleets will grow very rapidly over the next ten years," according to Rhombus' report. But that means many fleet staging areas will have trouble securing sufficient charging capacity as electric truck fleets scale up.

"Given the amount of time it takes to add new megawatt-level power feeds in most cities (think years), fleet EVs will run into a significant 'power crisis' by 2030," according to Rhombus.

"Grid power availability will become a significant problem for fleets as they increase the number of electric vehicles they operate," Rhombus CEO Rick Sander said in a statement. "Integrating energy storage with vehicle-to-grid capable chargers and smart [energy management system] solutions as seen in California grid stability efforts is a quick and effective mitigation strategy for this issue."

Along with energy storage, Guidehouse says a new, more flexible approach to charger deployment enabled by grid coordination strategies will help meet demand. That means chargers deployed by a van or other mobile stations, and "temporary" chargers that can help fleets expand capacity. 

According to Guidehouse, the temporary units "are well positioned to de-risk large investments in stationary charging infrastructure" while also providing charge point networks and service providers "with new capabilities to flexibly supply predictable changes in EV transportation behaviors and demand surges."

"Mobile charging is a bit of a new area in the EV charging scene. It primarily leverages batteries to make chargers mobile, but it doesn't necessarily have to," Guidehouse Senior Research Analyst Scott Shepard told Utility Dive. 

"The biggest opportunity is with the temporary charging format," said Shepard. "The bigger units are meant to be located at a certain site for a period of time. Those units are interesting because they create a little more scale-ability for sites and a little risk mitigation when it comes to investing in a site."

"Utilities could use temporary chargers as a way to provide more resilient service, using these chargers in line with on-site generation," Shepard said.

Increasing rates of EV adoption, combined with advances in battery size and charging rates, "will impact electric utility distribution infrastructure at a higher rate than previously projected," according to new analysis from FleetCarma.

The charging company conducted a study of over 3,900 EVs, illustrating the rapid change in vehicle capabilities in just the last five years. According to FleetCarma, today's EVs use twice as much energy and draw it at twice the power level. The long-range EV has increased as a proportion of new electric vehicle sales from 14% in 2014 to 66% in 2019 in the United States, it found.

Long-range EVs "are very different from older electric vehicles: they are driven more, they consume more energy, they draw power at a higher level and they are less predictable," according to FleetCarma.

Guidehouse analysts say grid modernization efforts and energy storage can help smooth the impacts of charging larger vehicles. 

Mobile and temporary charging solutions can act as a "buffer" to the distribution grid, according to Guidehouse's report, allowing utilities to avoid or defer some transmission and distribution upgrade costs that could be required due to stress on the grid from newer vehicles.

"At a high level, there's enough power and energy to supply EVs with proper management in place," said Shepard. "And in a lot of different locations, those charging deployments will be built in a way that protects the grid. Public fast charging, large commercial sites, they're going to have the right infrastructure embedded."

"But for certain areas of the grid where there is low visibility, there is the potential for grid disruption and questions about whether the UK grid can cope with EV demand," said Shepard. "This has been on the mind of utilities but never realized: overwhelming residential transformers."

As EVs with higher charging and energy capacities are connected to the grid, Shepard said, "you are going to start to see some of those residential systems come under pressure, and probably see increased incidences of having to upgrade transformers." Some residential upgrades can be deferred through smarter charging programs, he added.

In Europe, A Push For Electricity To Solve The Climate Dilemma

EU Electrification Strategy 2050 outlines shifting transport, buildings, and industry to clean power, accelerating EV adoption, heat pumps, and direct electrification to meet targets, reduce emissions, and replace fossil fuels with renewables and low-carbon grids.

 

Key Points

EU plan to cut emissions 95% by 2050 by electrifying transport, buildings and industry with clean power.

✅ 60% of final energy from electricity by 2050

✅ EVs dominate transport; up to 63% electric share

✅ Heat pumps electrify buildings; industry to 50% direct

 

The European Union has one of the most ambitious carbon emission reduction goals under the global Paris Agreement on climate change – a 95% reduction by 2050.

It seems that everyone has an idea for how to get there. Some are pushing nuclear energy. Others are pushing for a complete phase-out of fossil fuels and a switch to renewables.

Today the European electricity industry came out with their own plan, amid expectations of greater electricity price volatility in Europe in the coming years. A study published today by Eurelectric, the trade body of the European power sector, concludes that the 2050 goal will not be possible without a major shift to electricity in transport, buildings and industry.

The study finds that for the EU to reach its 95% emissions reduction target, electricity needs to cover at least 60 percent of final energy consumption by 2050. This would require a 1.5 percent year-on-year growth of EU electricity use, with evidence that EVs could raise electricity demand significantly in other markets, while at the same time reducing the EU’s overall energy consumption by 1.3 percent per year.

Transport is one of the areas where electrification can deliver the most benefit, because an electric car causes far less carbon emissions than a conventional vehicle, with e-mobility emerging as a key driver of electricity demand even if that electricity is generated in a fossil fuel power plant.

In the most ambitious scenario presented by the study, up to 63 percent of total final energy consumption in transport will be electric by 2050, and some analyses suggest that mass adoption of electric cars could occur much sooner, further accelerating progress.

Building have big potential as well, according to the study, with 45 to 63 percent of buildings energy consumption could be electric in 2050 by converting to electric heat pumps. Industrial processes could technically be electrified with up to 50 percent direct electrification in 2050, according to the study. The relative competitiveness of electricity against other carbon-neutral fuels will be the critical driver for this shift, but grid carbon intensity differs across markets, such as where fossil fuels still supply a notable share of generation.

Disruptions in the U.S. coal, nuclear power industries strain the economy and invite brownouts

Electric power market crisis highlights grid reliability risks as coal and nuclear retire amid subsidies, mandates, and cheap natural gas; intermittent wind and solar raise blackout concerns, resilience costs, and pricing distortions across regulated markets.

 

Key Points

Reliability and cost risks as coal and nuclear retire; subsidies distort prices; intermittent renewables strain grid.

✅ Coal and nuclear retirements reduce baseload capacity

✅ Subsidies and mandates distort market pricing signals

✅ Intermittent renewables increase blackout and grid risk

 

Is anyone paying any attention to the crisis that is going on in our electric power markets?

Over the past six months at least four major nuclear power plants have been slated for shutdown, including the last one in operation in California. Meanwhile, dozens of coal plants have been shuttered as well — despite low prices and cleaner coal. Some of our major coal companies may go into bankruptcy.

This is a dangerous game we are playing here with our most valuable resource — outside of clean air and water. Traditionally, we've received almost half our electric power nationwide from coal and nuclear power, and for good reason. They are cheap sources of power and they are highly resilient and reliable.

The disruption to coal and nuclear power wouldn't be disturbing if this were happening as a result of market forces. That's only partially the case.

#google#

The amazing shale oil and gas revolution is providing Americans with cheap gas for home heating and power generation. Hooray. The price of natural gas has fallen by nearly two-thirds over the last decade and this has put enormous price pressure on other forms of power generation.

But this is not a free-market story of Schumpeterian creative destruction. If it were, then wind and solar power would have been shutdown years ago. They can't possibly compete on a level playing field with $3 natural gas.

In most markets solar and wind power survive purely because the states mandate that as much as 30 percent of residential and commercial power come from these sources. The utilities have to buy it regardless of price, even as electricity demand is flat in many regions. What a sweet deal. The California state legislature just mandated that every new home spend $10,000 on solar panels on the roof.

Well over $100 billion of subsidies to big wind and big solar were doled out over the last decade, and even with the avalanche of taxpayer subsidies and bailout funds many of these companies like Solyndra (which received $500 million in handouts) failed, underscoring why a green revolution hasn't materialized as promised.

These industries are not anywhere close to self sufficiency. In 2017 amid utility trends to watch the wind industry admitted that without a continuation of a multi-billion tax credit, the wind turbines would stop turning.

This combines with the left's war on coal through regulations that have destroyed coal plants in many areas. (Thank goodness for the exports of coal or the industry would be in much bigger trouble.)

Bottom line: Our power market is a Soviet central planner's dream come true and it is extinguishing our coal and nuclear industries.

 

Why should anyone care?

First, because government subsidies, regulations and mandates make electric power more expensive. Natural gas prices have fallen by two-thirds, but electric power costs have still risen in most areas — thanks to the renewable mandates.

More importantly, the electric power market isn't accurately pricing in the value of resilience and reliability. What is the value of making sure the lights don't go off? What is the cost to the economy and human health if we have rolling brownouts and blackouts because the aging U.S. grid doesn't have enough juice during peak demand.

Politicians, utilities and federal regulators are shortsightedly killing our coal and nuclear capacities without considering the risk of future energy shortages and power disruptions. Once a nuclear plant is shutdown, you can't just fire it back up again when you need it.

Wind and solar are notoriously unreliable. Most places where wind power is used, coal plants are needed to back up the system during peak energy use and when the wind isn't blowing.

The first choice to fix energy markets is to finally end the tangled web of layers and layers of taxpayer subsidies and mandates and let the market choose. Alas, that's nearly impossible given the political clout of big wind and solar.

The second best solution is for the regulators and utilities to take into account the grid reliability and safety of our energy. Would people be willing to pay a little more for their power to ensure against brownouts? I sure would. The cost of having too little energy far exceeds the cost of having too much.

A glass of water costs pennies, but if you're in a desert dying of thirst, that water may be worth thousands of dollars.

I'll admit I'm not sure what the best solution is to the power plant closures. But if we have major towns and cities in the country without electric power for stretches of time because of green energy fixation, Americans are going to be mighty angry and our economy will take a major hit.

When our manufacturers, schools, hospitals, the internet and iPhones shut down, we're not going to think wind and solar power are so chic.

If the lights start to go out five or 10 years from now, we will look back at what is happening today and wonder how we could have been so darn stupid.
