A solar-powered house built by a group of Texas students offers a blueprint for recession-hit U.S. families to reduce their carbon dioxide emissions and their electricity bills without busting their budget.

The Zerow House, built by students at Rice University in Houston, will compete against other solar homes in Washington D.C. in October as part of the Solar Decathlon sponsored by the U.S. Energy Department.

But unlike some of its competitors, which are integrating high-concept, high-price features like tricked-out home entertainment systems and moving solar arrays that track the sun, the Rice team's aim is affordability.

A quest for low-emission energy sources and looming first-ever U.S. regulations on carbon dioxide emissions have sparked renewed interest in solar power, which until recent years has been in an extended infancy in the United States since it was invented in 1954 by Bell Labs.

"This competition is for showing the public that solar energy is here now and applicable to housing," said Roque Sanchez, a Rice graduate student. "We're taking a house that any family could live in and any family could afford and adding solar to it."

In fact, Rice plans to donate the home to a low-income Houston family after the competition.

The house, about the size of a New York-style efficiency apartment, is a case study in frugality, and could easily be built in Houston for about $100,000, Sanchez said.

Its exterior has a no-nonsense, low-maintenance metal skin meant to bear up against the Gulf Coast region's hurricane-force winds, and a lattice of vines hangs off the front to shield it from the brutal Texas sun.

Inside, it sports off-the-shelf, affordable appliances and cabinetry from stores like Ikea and Home Depot.

Thanks to strong government incentives, Germany is the world's biggest solar market and is expected to remain so until 2013, when the United States will become its equal. China will be slightly behind, according to research firm Lux Research.

The growing market will be a boon for companies like Suntech Power Holdings Co Ltd and SunPower Corp, that make solar panels. The U.S. solar market could triple in 2010 from about 350 megawatts this year, Suntech said.

Rice's entry is in contrast to other entries, like Team Germany from Technische Universitat Darmstadt whose aim is to "push the envelope with as many new technologies as possible," according to the contest's website.

Team Germany, which won top honors in the last contest in 2007, is fielding a modernistic, two-story cube covered with solar cells that can generate 11.1 kilowatts of power — nearly three times the capacity of the Rice house.

But Sanchez said such high-tech houses miss the goal of making solar technology affordable to Main Street because they cost roughly five times as much as the Rice design.

"We've seen teams with half a million-euro houses," he said. "For something that's 500 square feet that's absolutely ridiculous."

That's not to say that Rice's home is low-tech.

Its interior is lit by light-emitting diode strips that collectively use less energy than two standard 100-watt bulbs, and its "smart meter" technology enables residents to sell spare energy from its solar cells back to the local utility, and monitor their energy usage on the Internet.

UK homes can become virtual power plants to avoid outages

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

 

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

 

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.

Vehicle-to-grid could be ‘capacity on wheels’ for electricity networks

Vehicle-to-Grid (V2G) enables EV batteries to provide grid balancing, flexibility, and demand response, integrating renewables with bidirectional charging, reducing peaker plant reliance, and unlocking distributed energy storage from millions of connected electric vehicles.

 

Key Points

Vehicle-to-Grid (V2G) lets EVs export power via bidirectional charging to balance grids and support renewables.

✅ Turns parked EVs into distributed energy storage assets

✅ Delivers balancing services and demand response to the grid

✅ Cuts peaker plant use and supports renewable integration

 

“There are already many Gigawatt-hours of batteries on wheels”, which could be used to provide balance and flexibility to electrical grids, if the “ultimate potential” of vehicle-to-grid (V2G) technology could be harnessed.

That’s according to a panel of experts and stakeholders convened by our sister site Current±, which covers the business models and technologies inherent to the low carbon transition to decentralised and clean energy. Focusing mainly on the UK grid but opening up the conversation to other territories and the technologies themselves, representatives including distribution network operator (DNO) Northern Powergrid’s policy and markets director and Nissan Europe’s director of energy services debated the challenges, benefits and that aforementioned ultimate potential.

Decarbonisation of energy systems and of transport go hand-in-hand amid grid challenges from rising EV uptake, with vehicle fuel currently responsible for more emissions than electricity used for energy elsewhere, as Ian Cameron, head of innovation at DNO UK Power Networks says in the Q&A article.

“Furthermore, V2G technology will further help decarbonisation by replacing polluting power plants that back up the electrical grid,” Marc Trahand from EV software company Nuvve Corporation added, pointing to California grid stability initiatives as a leading example.

While the panel states that there will still be a place for standalone utility-scale energy storage systems, various speakers highlighted that there are over 20GWh of so-called ‘batteries on wheels’ in the US, capable of powering buildings as needed, and up to 10 million EVs forecast for Britain’s roads by 2030.

“…it therefore doesn’t make sense to keep building expensive standalone battery farms when you have all this capacity on wheels that just needs to be plugged into bidirectional chargers,” Trahand said.

Lawmakers question FERC licensing process for dams in West Virginia

FERC Hydropower Licensing Dispute centers on FERC authority, Clean Water Act compliance, state water quality certifications, Federal Power Act timelines, and Army Corps dams on West Virginia's Monongahela River licenses.

 

Key Points

An inquiry into FERC's licensing process and state water quality authority for hydropower at Monongahela River dams.

✅ Questions on omitted state water quality conditions

✅ Debate over starting Clean Water Act certification timelines

✅ Potential impacts on states' rights and licensing schedules

 

As federal lawmakers, including Democrats pressing FERC, plan to consider a bill that would expand Federal Energy Regulatory Commission (FERC) licensing authority, questions emerged on Tuesday about the process used by FERC to issue two hydropower licenses for existing dams in West Virginia.

In a letter to FERC Chairman Neil Chatterjee, Democratic leaders of the House Energy and Commerce Committee, as electricity pricing changes were being debated, raised questions about hydropower licenses issued for two dams operated by the U.S. Army Corps of Engineers on the Monongahela River in West Virginia.

U.S. Reps. Frank Pallone Jr. (D-NJ), the ranking member of the Subcommittee on Energy, Bobby Rush (D-IL), the ranking member of the Subcommittee on Environment, and John Sarbanes (D-MD), amid Maryland clean energy enforcement concerns, questioned why FERC did not incorporate all conditions outlined in a West Virginia Department of Environmental Protection water quality certificate into plans for the projects.

“By denying the state its allotted time to review this application and submit requirements on these licenses, FERC is undermining the state’s authority under the Clean Water Act and Federal Power Act to impose conditions that will ensure water quality standards are met,” the letter stated.

The House of Representatives was slated to consider the Hydropower Policy Modernization Act of 2017, H.R. 3043, later in the week. The measure would expand FERC authority over licensing processes, a theme mirrored in Maine's transmission line debate over interstate energy projects. Opponents of the bill argue that the changes would make it more difficult for states to protect their clean water interests.

West Virginia has announced plans to challenge FERC hydropower licenses for the dams on the Monongahela River, echoing Northern Pass opposition seen in New Hampshire.

New England Emergency fuel stock to cost millions

Inventoried Energy Program pays ISO-NE generators for fuel security to boost winter reliability, with FERC approval, covering fossil, nuclear, hydropower, and batteries, complementing capacity markets to enhance grid resilience during severe cold snaps.

 

Key Points

ISO-NE program paying generators to hold fuel or energy reserves for emergencies, boosting winter reliability.

✅ FERC-approved stopgap for 2023 and 2024 winter seasons

✅ Pays for on-site fuel or stored energy during cold-trigger events

✅ Open to fossil, nuclear, hydro, batteries; limited gas participation

 

Electricity ratepayers in New England will pay tens of millions of dollars to fossil fuel and nuclear power plants later this decade under a program that proponents say is needed to keep the lights on during severe winters but which critics call a subsidy with little benefit to consumers or the grid, even as Connecticut is pushing a market overhaul across the region.

Last week the Federal Energy Regulatory Commission said ISO-New England, which runs the six-state power grid, can create what it calls the Inventoried Energy Program or IEP. This basically will pay certain power plants to stockpile of fuel for use in emergencies during two upcoming winters as longer-term solutions are developed.

The federal commission called it a reasonable short-term solution to avoid brownouts which doesn’t favor any given technology.

Not all agree, however, including FERC Commissioner Richard Glick, who wrote a fiery dissent to the other three commissioners.

“The program will hand out tens of millions of dollars to nuclear, coal and hydropower generators without any indication that those payments will cause the slightest change in those generators’ behavior,” Glick wrote. “Handing out money for nothing is a windfall, not a just and reasonable rate.”

The program is the latest reaction by ISO-NE to the winter of 2013-14 when New England almost saw brownouts because of a shortage of natural gas to create electricity during a pair of week-long deep freezes.

ISO-New England says the situation is more critical now because of the possible retirement of the gas-fired Mystic Generating Station in Massachusetts. As with closed nuclear plants such as Vermont Yankee and Pilgrim in Massachusetts, power plant owners say lower electricity prices, partly due to cheap renewables and partly to stagnant demand, means they can’t be profitable just by selling power.

Programs like the IEP are meant to subsidize such plants – “incentivize” is the industry term – even though some argue there is no need to subsidize nuclear in deregulated markets so they’ll stay open if they are needed.

The IEP approved last week will be applied to the winters of 2023 and 2024, after a different subsidy program expires. It sets prices, despite warnings about rushing pricing changes from industry groups, for stocking certain amounts of fuel and payments during any “trigger” event, defined as a day when the average of high and low temperatures at Bradley International Airport in Connecticut is no more than 17 degrees Fahrenheit.

These payments will be made on top of a complex system of grid auctions used to decide how much various plants get paid for generating electricity at which times.

ISO-NE estimates the new program will cost between $102 million and $148 million each winter, depending on weather and market conditions.

It says the payments are open to plants that burn oil, coal, nuclear fuel, wood chips or trash; utility-scale battery storage facilities; and hydropower dams “that store water in a pond or reservoir.” Natural gas plants can participate if they guarantee to have fuel available, but that seems less likely because of winter heating contracts.

A major complaint and groups that filed petitions opposing the project is that ISO-NE presented little supporting evidence of how prices, amount and overall cost were determined. ISO-NE argued that there wasn’t time for such analysis before the Mystic shutdown, and FERC agreed.

“The proposal is a step in the right direction … while ISO-NE finishes developing a long-term market solution,” the commission said in its ruling.

The program is the latest example of complexities facing the nation’s electricity system evolves in the face of solar and wind power, which produce electricity so cheaply that they can render traditional power uneconomic but which can’t always produce power on demand, prompting discussions of Texas grid improvements among policymakers. Another major factor is climate change, which has increased the pressure to support renewable alternatives to plants that burn fossil fuels, as well as stagnant electricity demand caused by increased efficiency.

Opponents, including many environmental groups, say electricity utilities and regulators are too quick to prop up existing systems, as the 145-mile Maine transmission line debate shows, built when electricity was sent one way from a few big plants to many customers. They argue that to combat climate change as well as limit cost, the emphasis must be on developing “non-wire alternatives” such as smart systems for controlling demand, in order to take advantage of the current system in which electricity goes two ways, such as from rooftop solar back into the grid.

U.S. Senate Looks to Modernize Renewable Energy on Public Land

PLREDA 2019 advances solar, wind, and geothermal on public lands, guiding DOI siting, improving transmission access, streamlining permitting, sharing revenues, and funding conservation to meet climate goals while protecting wildlife and recreation.

 

Key Points

A bipartisan bill to expand renewables on public lands fund conservation, speed permitting and advance U.S. climate aims.

✅ Targets 25 GW of public-land renewables by 2025

✅ Establishes wildlife conservation and recreation access funds

✅ Streamlines siting, transmission, and equitable revenue sharing

 

The Senate unveiled its version of a bill the House introduced in July to help the U.S. realize the extraordinary renewable energy potential of our shared public lands.

Senator Martha McSally (R-AZ) and a bipartisan coalition of western Senators introduced a Senate version of draft legislation that will help the Department of the Interior tap the renewable energy potential of our shared public lands. The western Senators represent Arizona, New Mexico, Colorado, Montana, and Idaho.

Elsewhere in the West, lawmakers have moved to modernize Oregon hydropower to streamline licensing, signaling broad regional momentum.

The Public Land Renewable Energy Development Act of 2019 (PLREDA) facilitates siting of solar, wind, and geothermal energy projects on public lands, boosts funding for conservation, and promotes ambitious renewable energy targets that will help the U.S. take action on the climate crisis.

Like the House version, the Senate bill enjoys strong bi-partisan support and industry endorsement. The Senate version makes few notable changes to the bill introduced in July by Representatives Mike Levin (D-CA) and Paul Gosar (R-AZ). It includes:

  • A commitment to enhance natural resource conservation and stewardship via the establishment of a fish and wildlife conservation fund that would support conservation and restoration work and other important stewardship activities.
  • An ambitious renewable energy production goal for the Department of the Interior to permit a total of 25 gigawatts of renewable energy on public lands by 2025—nearly double the current generating capacity of projects currently on our public lands.
  • Establishment of criteria for identifying appropriate areas for renewable energy development using the 2012 Western Solar Plan as a model. Key criteria to be considered include access to transmission lines and likelihood of avoiding or minimizing conflict with wildlife habitat, cultural resources, and other resources and values.
  • Improved public access to Federal lands for recreational uses via funds made available for preserving and improving access, including enhancing public access to places that are currently inaccessible or restricted.
  • Sharing of revenues raised from renewable energy development on public lands in an equitable manner that benefits local communities near new renewable energy projects and supports the efficient administration of permitting requirements.
  • Creating incentives for renewable energy development by giving Interior the authority to reduce rental rates and capacity fees to ensure new renewable energy development remains competitive in the marketplace.

NRDC strongly supports this legislation, and we will do our utmost to facilitate its passage into law. There is no question that in our era of runaway climate change, legislation that balances energy production with environmental conservation and stewardship of our public lands is critical.

PLREDA takes a balanced approach to using our public lands to help lead the U.S. toward a low-carbon future, as states pursue 100% renewable electricity goals nationwide. The bill outlines a commonsense approach for federal agencies to play a meaningful role in combatting climate change.

Groups clash over NH hydropower project

Northern Pass Hydropower Project Rehearing faces review by New Hampshire's Site Evaluation Committee as Eversource seeks approval for a 192-mile transmission line, citing energy cost relief, while Massachusetts eyes Central Maine Power as an alternative.

 

Key Points

A review of Eversource's halted NH transmission plan, weighing impacts, costs, and alternatives.

✅ SEC denied project, Eversource seeks rehearing

✅ 192-mile line to bring Canadian hydropower to NE

✅ Alternative bids include Central Maine Power corridor

 

Groups supporting and opposing the Northern Pass hydropower project in New Hampshire filed statements Friday in advance of a state committee’s meeting next week on whether it should rehear the project.

The Site Evaluation Committee rejected the transmission proposal last month over concerns about potential negative impacts. It is scheduled to deliberate Monday on Eversource’s request for a rehearing.

The $1.6 billion project would deliver hydropower from Canada, including Hydro-Quebec exports, to customers in southern New England through a 192-mile transmission line in New Hampshire.

If the Northern Pass project fails to ultimately win New Hampshire approval, the Massachusetts Department of Energy Resources has announced it will begin negotiating with a team led by Central Maine Power Co. for a $950 million project through a 145-mile Maine transmission line as an alternative.

Separately, construction later began on the disputed $1 billion electricity corridor despite ongoing legal and political challenges.

The Business and Industry Association voted last month to endorse the project after remaining neutral on it since it was first proposed in 2010. A letter sent to the committee Friday urges it to resume deliberations. The association said it is concerned about the severe impact the committee’s decision could have on New Hampshire’s economic future, even as Connecticut overhauls electricity market structure across New England.

“The BIA believes this decision was premature and puts New Hampshire’s economy at risk,” organization President Jim Roche wrote. “New Hampshire’s electrical energy prices are consistently 50-60 percent higher than the national average. This has forced employers to explore options outside New Hampshire and new England to obtain lower electricity prices. Businesses from outside New Hampshire and others now here are reversing plans to grow in New Hampshire due to the Site Evaluation Committee’s decision.”

The International Brotherhood of Electrical Workers and the Coos County Business and Employers Group also filed a statement in support of rehearing the project.

The Society to Protect New Hampshire Forests, which is opposed to the project, said Eversource’s request is premature because the committee hasn’t issued a final written decision yet. It also said Eversource hasn’t proven committee members “made an unlawful or unreasonable decision or mistakenly overlooked matters it should have considered.”

As part of its request for reconsideration, Eversource said it is offering up to $300 million in reductions to low-income and business customers in the state.

It also is offering to allocate $95 million from a previously announced $200 million community fund — $25 million to compensate for declining property values, $25 million for economic development and $25 million to promote tourism in affected areas. Another $20 million would fund energy efficiency programs.
