San Francisco solar startup GreenVolts announced an agreement to build a demonstration solar power plant for Pacific Northwest utility Avista. GreenVolts was one of the companies featured in Green Wombat's Big Solar story that appeared in the June issue of Business 2.0.

Avista (AVA), based in Spokane, Washington, will also make a "strategic investment" in GreenVolts. The terms of the deal were not disclosed. GreenVolts has developed a high concentration photovoltaic technology that features microdishes that track the sun and focus its rays on small but highly efficient solar cells. Rotating platforms hold 176 of the dishes.

GreenVolts 1-to-20-megawatt power plants are designed to be placed near cities or utility substations to provide electricity during peak demand without the need for new transmissions lines or other infrastructure that often must be built for large-scale solar power plants located in the desert. In other words, GreenVolts offers a plug-in power plant designed to save utilities from having to crank up fossil-fueled power stations to provide electricity when demand soars in the afternoon.

GreenVolts is Exhibit A in how renewable energy mandates are creating opportunities for startups to break into the Big Power business. Founded in 2005 by Internet marketing veteran Bob Cart, GreenVolts is located in downtown San Francisco's "green grid" - it's a short stroll from the GreenVolts office to companies like utility PG&E (PCG) and solar financier MMA Renewable Ventures (MMA).

GreenVolts got its first big boost when it was named a winner of the California Clean Tech Open startup contest, scoring a $120,000 package that included office space from PG&E. That opened doors in Silicon Valley and allowed Cart to raise $1.5 million in seed financing as well as attract John Woolard, CEO of utility-scale solar power company BrightSource Energy, to his board.

When Green Wombat first interviewed Cart, GreenVolts had just moved into its new offices and the bare-bones decor was pure startup. "We plug in directly to distribution system rather than being far away from the loads using the transmission grid," says Cart, 42. "And that means we donÂ’t have to pay the cost of transmission and donÂ’t have the losses and environmental impact of desert-sited systems."

Of course, GreenVolts will only score contracts with utilities if its plug-in power plants can produce electricity at competitive - or near competitive - rates. The key to doing that is the company's technology, according to Cart. He disappears and returns carrying a prototype of the GreenVolts microdish. It's about the size of an overhead projector - remember those? - and features a curved mirror that faces a module holding a tiny solar cell about the size a cameraphone lens.

GreenVolts licensed the mirror technology from Lawrence Livermore Laboratories.

"It gives us a mirror that is low-cost to produce, is highly reflective and highly durable," says Cart. The design allows the sun to be intensely concentrated on the solar cell, which is made by Boeing's (BA) Spectrolab subsidiary and is the world's most efficient at converting photons into electrons. The dish contains an automated pressure washing system, which keeps mirror clean and thus its efficiency high while reducing maintenance costs. The off-axis design prevents shade from falling on the dish when the sun is directly overhead.

Cart tapped the expertise of a cadre of engineers to help design the GreenVolts system, paying them in stock. GreenVolts' manufacturing VP is the CEO of Spokane fabrication company Ecolite, which is performing the mechanical design and assembly of the dishes and platform, which GreenVolts calls a CarouSol.

The company is negotiating a second power plant deal with a large utility Cart declined to identify. He says GreenVolts already has signed a lease for farmland that will be the site of a power plant and plans to be in production by June 2008. That gives Cart less than a year to perform all the testing and validation to ensure his technology delivers on its promise.

"ItÂ’s answering the question of how do you prove this will work for 20 years in a year," he says. "With a yearÂ’s worth of testing how do you tell itÂ’s going to last for 20. ThatÂ’s a challenge. We think we have good answers for that. We think we have the right idea, we think we have a way to get this off the ground and we think the demand for it is going to be phenomenal."

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%.

Heating and Electricity Costs in Germany Set to Rise

Germany 2025 Energy Costs forecast electricity and heating price trends amid gas volatility, renewables expansion, grid upgrades, and policy subsidies, highlighting impacts on households, industries, efficiency measures, and the Energiewende transition dynamics.

 

Key Points

Electricity stabilizes, gas-driven heating stays high; renewables, subsidies, and efficiency measures moderate costs.

✅ Power prices stabilize above pre-crisis levels

✅ Gas volatility keeps heating bills elevated

✅ Subsidies and efficiency upgrades offset some costs

 

As Germany moves into 2025, the country is facing significant shifts in heating and electricity costs. With a variety of factors influencing energy prices, including geopolitical tensions, government policies, and the ongoing transition to renewable energy sources, consumers and businesses alike are bracing for potential changes in their energy bills. In this article, we will explore how heating and electricity costs are expected to evolve in Germany in the coming year and what that means for households and industries.

Energy Price Trends in Germany

In recent years, energy prices in Germany have experienced notable fluctuations, particularly due to the aftermath of the global energy crisis, which was exacerbated by the Russian invasion of Ukraine. This geopolitical shift disrupted gas supplies, which in turn affected electricity prices and strained local utilities across the country. Although the German government introduced measures to mitigate some of the price increases, many households have still felt the strain of higher energy costs.

For 2024, experts predict that electricity prices will likely stabilize but remain higher than pre-crisis levels. While electricity prices nearly doubled in 2022, they have gradually started to decline, and the market has adjusted to the new realities of energy supply and demand. Despite this, the cost of electricity is expected to stay elevated as Germany continues to phase out coal and nuclear energy while ramping up the use of renewable sources, which often require significant infrastructure investments.

Heating Costs: A Mixed Outlook

Heating costs in Germany are heavily influenced by natural gas prices, which have been volatile since the onset of the energy crisis. Gas prices, although lower than the peak levels seen in 2022, are still considerably higher than in the years before. This means that households relying on gas heating can expect to pay more for warmth in 2024 compared to previous years.

The government has implemented measures to cushion the impact of these increased costs, such as subsidies for vulnerable households and efforts to support energy efficiency upgrades. Despite these efforts, consumers will still feel the pinch, particularly in homes that use older, less efficient heating systems. The transition to more sustainable heating solutions, such as heat pumps, remains a key goal for the German government. However, the upfront cost of such systems can be a barrier for many households.

The Role of Renewable Energy and the Green Transition

Germany has set ambitious goals for its energy transition, known as the "Energiewende," which aims to reduce reliance on fossil fuels and increase the share of renewable energy sources in the national grid. In 2024, Germany is expected to see further increases in renewable energy generation, particularly from wind and solar power. While this transition is essential for reducing carbon emissions and improving long-term energy security, the shift comes with its own challenges already documented in EU electricity market trends reports.

One of the main factors influencing electricity costs in the short term is the intermittency of renewable energy sources. Wind and solar power are not always available when demand peaks, requiring backup power generation from fossil fuels or stored energy. Additionally, the infrastructure needed to accommodate a higher share of renewables, including grid upgrades and energy storage solutions, is costly and will likely contribute to rising electricity prices in the near term.

On a positive note, Germany's growing investment in renewable energy is expected to make the country less reliant on imported fossil fuels, particularly natural gas, which has been a major source of price volatility. Over time, as the share of renewables in the energy mix grows, the energy system should become more stable and less susceptible to geopolitical shocks, which could lead to more predictable and potentially lower energy costs in the long run.

Government Interventions and Subsidies

To help ease the burden on consumers, the German government has continued to implement various measures to support households and businesses. One of the key programs is the reduction in VAT (Value Added Tax) on electricity, which has been extended in some regions. This measure is designed to make electricity more affordable for all households, particularly those on fixed incomes facing EU energy inflation pressures that have hit the poorest hardest.

Moreover, the government has been providing financial incentives for households and businesses to invest in energy-efficient technologies, such as insulation and energy-saving heating systems, complementing the earlier 200 billion euro energy shield announced to buffer surging prices. These incentives are intended to reduce overall energy consumption, which could offset some of the rising costs.

The outlook for heating and electricity costs in Germany for 2024 is mixed, even as energy demand hit a historic low amid economic stagnation. While some relief from the extreme price spikes of 2022 may be felt, energy costs will still be higher than they were in previous years. Households relying on gas heating will likely see continued elevated costs, although those who invest in energy-efficient solutions or renewable heating technologies may be able to offset some of the increases. Similarly, electricity prices are expected to stabilize but remain high due to the country’s ongoing transition to renewable energy sources.

While the green transition is crucial for long-term sustainability, consumers must be prepared for potentially higher energy costs in the short term. Government subsidies and incentives will help alleviate some of the financial pressure, but households should consider strategies to reduce energy consumption, such as investing in more efficient heating systems or adopting renewable energy solutions like solar panels.

As Germany navigates these changes, the country’s energy future will undoubtedly be shaped by a delicate balance between environmental goals and the economic realities of transitioning to a greener energy system.

Energy prices trigger EU inflation, poor worst hit

EU Energy Price Surge is driving up electricity and gas costs, inflation, and cost of living across the EU, prompting tax cuts, price caps, subsidies, and household support measures in France, Italy, Spain, and Germany.

 

Key Points

A surge in EU gas and electricity costs driving inflation and prompting government subsidies, tax cuts, and price caps.

✅ Low-income EU households now spend 50-70 percent more on energy.

✅ Governments deploy tax cuts, price caps, and direct subsidies.

✅ Gas-dependent power markets drive electricity price spikes.

 

Higher energy prices, including for natural gas, are pushing up electricity prices and the cost of living for households across the EU, prompting governments to cut taxes and provide financial support to the tune of several billion euros.

In the United Kingdom, households are bracing for high winter energy bills this season.

A series of reports published by Cambridge Econometrics in October and November 2022 found that households in EU countries are spending much more on energy than in 2020 and that governments are spending billions of euros to help consumers pay bills and cut taxes.

In France, for example, the poorest households now spend roughly one-third more on energy than in 2020. Between August 2020 and August 2022, household energy prices increased by 37 percent, while overall inflation increased by 9.2 percent.

“We estimate that the increase in household energy prices make an average French household €410 worse off in 2022 compared to 2020, mostly due to higher gas prices,” said the report.

In response to rising energy prices, the French government has adopted price caps and support measures forecast to cost over €71 billion, equivalent to 2.9 percent of French GDP, according to the U.K.-based consultancy.

In Italy, fossil fuels alone were responsible for roughly 30 percent of the country’s annual rate of inflation during spring 2022, according to Cambridge Econometrics. Unlike in other European countries, retail electricity prices have outpaced other energy prices in Italy and were 112 percent higher in July 2022 than in August 2020, the report found. Over the same time period, retail petrol prices were up 14 percent, diesel up 22 percent, and natural gas up 42 percent.

We estimate that households in the lowest-income quintile now spend about 50 percent more on energy than in 2020.

“We estimate that before government support, an average Italian household will be spending around €1,400 more on energy and fuel bills this year than in 2020,” the report said. “Low-income households are worse affected by the increasing energy prices: we estimate that households in the lowest-income quintile now spend about 50 percent more on energy than in 2020.”

Electricity production in Italy is dominated by natural gas, which has also led to a spike in wholesale electricity prices. In 2010, natural gas accounted for 50 percent of all electricity production. The share of natural gas fell to 33 percent in 2014, but then rose again, reaching 48 percent in 2021, and 56 percent in the first half of 2022, according to the report, as gas filled the gap of record low hydro power production in 2022.

In Spain, where electricity prices have seen extreme spikes, low-income households are now spending an estimated 70% more on energy than in 2020, according to Cambridge Econometrics.


Low-income squeeze
In Spain, low-income households are now spending an estimated 70% more on energy than in 2020, according to Cambridge Econometrics. It noted that the Spanish government has intervened heavily in energy markets by cutting taxes, introducing cash transfers for households, and capping the price of natural gas for power generators. The latter has led to lower electricity prices than in many other EU countries.

These support measures are forecast to cost the Spanish government over €35 billion, equivalent to nearly 3 percent of Spain’s GDP. Yet consumers will still feel the burden of higher costs of living, and rolling back electricity prices may prove difficult in the near term.

In March, electricity prices alone were responsible for 45 percent of year-on-year inflation in Spain but prices have since fallen as a result of government intervention, Cambridge Econometrics said. Between May and July, fossil fuels prices accounted for 19-25 percent of the overall inflation rate, and electricity prices for 16 percent.


Support measures
Rising inflation is also a real challenge in Germany, Europe’s largest economy, where German power prices have surged this year, adding pressure. Also there, higher gas prices are to blame.

“We estimate that the increase in energy prices currently make an average household €735 worse off in 2022 compared to 2020, mostly due to higher gas prices,” Cambridge Econometrics said, in a report focused on Germany.

The German government has introduced a number of support measures in order to help households, businesses and industry to pay energy bills, amid rising heating and electricity costs for consumers, including price caps that are expected to take effect in March next year. Moreover, households’ energy bills for December this year will be paid by the state. According to the report, these interventions will mitigate the impact of higher prices “to some extent”, but the aid measures are forecast to cost the government nearly 5 percent of GDP.


Fossil-fuel effect
In addition to gas, higher coal prices have also pushed up inflation in some countries, and U.S. electricity prices have reached multi-decade highs as inflation endures.

In Poland, which is heavily dependent on coal for electricity generation, fossil fuels accounted for roughly 40 percent of Poland’s overall year-on-year inflation rate in June 2022, which stood at over 14 percent, the consultancy said.

The price of household coal, which is widely used in heating Polish homes, increased by 157 percent between August 2021 and August 2022.

Higher energy prices in Poland are partly due to Polish and EU sanctions against Russian gas and coal. Other drivers are the weakening of the Polish zloty against the U.S. dollar and the euro, and the uptick in global demand after COVID-19 lockdowns, said Cambridge Econometrics.

Electricity prices have risen at a much slower pace than energy for transport and heating, with an annualized increase of 5.1 percent.

U.S Bans Russian Uranium to Bolster Domestic Industry

U.S. Russian Uranium Import Ban reshapes nuclear fuel supply, bolstering energy security, domestic enrichment, and sanctions policy while diversifying reactor-grade uranium sources and supply chains through allies, waivers, and funding to sustain utilities and reliability.

 

Key Points

A U.S. law halting Russian uranium imports to boost energy security diversify nuclear fuel and revive U.S. enrichment.

✅ Cuts Russian revenue; reduces geopolitical risk.

✅ Funds U.S. enrichment; supports reactor fuel supply.

✅ Enables waivers to prevent utility shutdowns.

 

In a move aimed at reducing reliance on Russia and fostering domestic energy security for the long term, the United States has banned imports of Russian uranium, a critical component of nuclear fuel. This decision, signed into law by President Biden in May 2024, marks a significant shift in the U.S. nuclear fuel supply chain and has far-reaching economic and geopolitical implications.

For decades, Russia has been a major supplier of enriched uranium, a processed form of uranium used to power nuclear reactors. The U.S. relies on Russia for roughly a quarter of its enriched uranium needs, feeding the nation's network of 94 nuclear reactors operated by utilities which generate nearly 20% of the country's electricity. This dependence has come under scrutiny in recent years, particularly following Russia's invasion of Ukraine.

The ban on Russian uranium is a multifaceted response. First and foremost, it aims to cripple a key revenue stream for the Russian government. Uranium exports are a significant source of income for Russia, and by severing this economic tie, the U.S. hopes to weaken Russia's financial capacity to wage war.

Second, the ban serves as a national energy security measure. Relying on a potentially hostile nation for such a critical resource creates vulnerabilities. The possibility of Russia disrupting uranium supplies, either through political pressure or in the event of a wider conflict, is a major concern. Diversifying the U.S. nuclear fuel supply chain mitigates this risk.

Third, the ban is intended to revitalize the domestic uranium mining and enrichment industry, building on earlier initiatives such as Trump's uranium order announced previously. The U.S. has historically been a major uranium producer, but environmental concerns and competition from cheaper foreign sources led to a decline in domestic production. The ban, coupled with $2.7 billion in federal funding allocated to expand domestic uranium enrichment capacity, aims to reverse this trend.

The transition away from Russian uranium won't be immediate. The law includes a grace period until mid-August 2024, and waivers can be granted to utilities facing potential shutdowns if alternative suppliers aren't readily available. Finding new sources of enriched uranium will require forging partnerships with other uranium-producing nations like Kazakhstan, Canada on minerals cooperation, and Australia.

The long-term success of this strategy hinges on several factors. First, successfully ramping up domestic uranium production will require overcoming regulatory hurdles and addressing environmental concerns, alongside nuclear innovation to modernize the fuel cycle. Second, securing reliable alternative suppliers at competitive prices is crucial, and supportive policy frameworks such as the Nuclear Innovation Act now in law can help. Finally, ensuring the continued safe and efficient operation of existing nuclear reactors is paramount.

The ban on Russian uranium is a bold move with significant economic and geopolitical implications. While challenges lie ahead, the potential benefits of a more secure and domestically sourced nuclear fuel supply chain are undeniable. The success of this initiative will be closely watched not only by the U.S. but also by other nations seeking to lessen their dependence on Russia for critical resources.

This Floating Hotel Will Generate Electricity By Rotating All Day

Floating Rotating Eco Hotel harnesses renewable energy via VAWTAU, recycles rainwater for greywater, and follows zero-waste principles. This mobile, off-grid, Qatar-based resort generates electricity by slow 360-degree rotation while offering luxury amenities.

 

Key Points

A mobile, off-grid hotel that rotates to generate power, uses VAWTAU, recycles greywater, and targets zero-waste.

✅ Rotates 360 deg in 24 hours to produce electricity

✅ VAWTAU system: vertical-axis turbine and sun umbrella

✅ Rain capture and greywater recycling minimize waste

 

A new eco-friendly, floating hotel plans to generate its own electricity by rotating while guests relax on board, echoing developments like the solar Marriott hotel in sustainable hospitality.

Led by Hayri Atak Architectural Design Studio (HAADS), the structure will be completely mobile, meaning it can float from place to place, never sitting in a permanent position. Building began in March 2020 and the architects aim for it to be up and running by 2025.

It will be based in Qatar, but has the potential to be located in different areas due to its mobility, and it sits within a region advancing projects such as solar hydrogen production that signal a broader clean-energy shift.

The design includes minimum energy loss and a zero waste principle at its core, aligning with progress in wave energy research that aims to power a clean future. As it will rotate around all day long, this will generate electrical energy to power the whole hotel.

But guests won’t feel too dizzy, as it takes 24 hours for the hotel to spin 360 degrees.

The floating hotel will stay within areas with continuous currents, to ensure that it is always rotating, drawing on ideas from ocean and river power systems that exploit natural flows. This type of green energy production is called ‘vawtau’ (vertical axis wind turbine and umbrella) which works like a wind turbine on the vertical axis, while alternative approaches like kite-based wind energy target stronger, high-altitude currents as well, and functions as a sun umbrella on the coastal band.

Beyond marine-current concepts such as underwater kites, the structure will also make use of rainwater to create power. A cover on the top of the hotel will collect rain to be used for greywater recycling. This is when wastewater is plumbed straight back into toilets, washing machines or outside taps to maximise efficiency.

The whole surface area is around 35,000 m², comparable in scale to emerging floating solar plants that demonstrate modular, water-based infrastructure, and there are a total of 152 rooms. It will have three different entrances so that there is access to the land at any time of the day, thanks to the 140-degree pier that surrounds it.

There will also be indoor and outdoor swimming pools, a sauna, spa, gym, mini golf course and other activity areas.
