Building an environmentally friendly, energy efficient, occupant friendly, affordable house is an art of compromises.

The most environmentally friendly house is no house at all, since if it doesnÂ’t exist, it doesnÂ’t use any energy or materials, and it doesnÂ’t impact the land, but it isnÂ’t very occupant friendly, since people generally want some form of shelter. You can also build a home that doesnÂ’t use any fossil fuels and generates all its own power, but it will be more expensive than most people can afford.

The goal is to create a house that makes a balance between the needs of the occupants, the needs of the environment and the budget of the owner.

Almost all houses can be made more efficient, and with the more money you have available, the more efficient it can be made. For those on a very limited budget, there are design methods that give a very high return for virtually no cost. An example of this is passive solar design which can be done for free, just by proper orientation of the house and the placement of windows.

For only slightly more cost, the use of larger, energy efficient, south facing windows and the placement of thermal mass, the heating costs of the house can be lowered by at least one quarter.

Further upgrades can be items such as more insulation in the walls and ceiling, which will further reduce the heating and cooling costs of the building. For increasing the insulation alternative building techniques, such as strawbale, double stud wall, Structured Insulated Panels (SIPs) and Insulated Concrete Forms (ICFs) are some common examples. These techniques can be used to either increase the amount of insulation in the walls, or to reduce the amount of air infiltration through the walls.

If the budget is larger, or as savings accumulate from energy savings, other systems can be added to reduce the enviromental footprint. An example would be adding a solar hot water heater to the home to generate hot water.

A solar hot water heater can supply up to 100% of the hot water for a home, particularly in the summer, and even in winter it can still significantly reduce the energy use. For those with a bigger budget, you can add a solar electric panels to the home to generate a portion, or even all the electricity used in the home.

With newer equipment, the solar panels can be connected directly to the power grid, and effectively store the excess energy generated during the day for use at night. In some areas, the electric utility will even pay the homeowner a premium for the excess solar power. If the site is suitable, electricity can also be generated using the wind or flowing water.

Even those with an existing home and no budget can reduce their energy usage by using conservation techniques, such as turning off lights when leaving a room and turning down the thermostat. So there is no excuse for anyone to not reduce their energy usage.

Opinion: With deregulated electricity, no need to subsidize nuclear power

Pennsylvania Electricity Market Deregulation has driven competitive pricing, leveraged low-cost natural gas, and spurred private investment, jobs, and efficient power plants, while nuclear subsidies threaten wholesale market signals and long-term consumer savings.

 

Key Points

Policy that opens generation to competition, leverages cheap gas, lowers rates, and resists subsidies for nuclear plants.

✅ Competitive wholesale pricing benefits consumers statewide

✅ Gas-driven plants add efficient, flexible capacity and jobs

✅ Nuclear subsidies distort market signals and raise costs

 

For decades, the government regulation of Pennsylvania's electricity markets dictated all aspects of power generation resources in the state, thus restricting market-driven prices for consumers and hindering new power plant development and investment.

Deregulation has enabled competitive markets to drive energy prices downward, as recent grid auction payouts fell 64% indicate, which has transformed Pennsylvania from a higher-electricity-cost state to one with prices below the national average.

Recently, the economic advantage of abundant low-cost natural gas has spurred an influx of billions of dollars of private capital investment and thousands of jobs to construct environmentally responsible natural gas power generation facilities throughout the commonwealth — including our three power generation facilities in operation and one presently under construction.

Calpine is an independent power provider with a national portfolio of 80 highly efficient power plants in operation or under construction with an electric generating capacity of approximately 26,000 megawatts. Collectively, these resources can provide sufficient power for more than 30 million residential homes. We are not a regulated utility receiving a guaranteed rate of return on investment. Rather, Calpine competes to sell wholesale power into the electric markets, and the economics of supply and demand are fundamental to the success of our business.

Pennsylvania's deregulated electricity market is working. Consumers are benefiting from low-cost natural gas, as broader evidence shows competition benefits consumers and the environment across markets, and companies such as Calpine are investing billions of dollars and creating thousands of jobs to build advanced, energy efficient, environmentally responsible and flexible power generating facilities.

There are presently seven electric generating projects under construction in the commonwealth, representing about a $7 billion capital investment that will produce about 7,000 megawatts of efficient electrical power, with additional facilities being planned.

Looking back 20 years following the enactment of the Pennsylvania Electricity Generation Customer Choice and Competition Act, Pennsylvania's regulators and policymakers must conclude that the results of a free and fair market-driven structure have delivered indisputable benefits to the consumer, even amid potential winter rate spikes for residents, and the Pennsylvania economy.

While consumers are now reaping the benefits of open and competitive electricity markets, we see challenges on the horizon that could threaten the foundation of those markets. Due to pressure from nuclear power generators, state policymakers throughout the nation have been increasing efforts to impact the generation mix in their respective states by offering ratepayer funded subsidies to existing nuclear generation resources or by considering a market structure overhaul in New England.

Subsidizing one power generation type over others is having a significant, negative impact on wholesale electric markets, competitive retails markets and ultimately the cost the consumer will have to pay, and can exacerbate disruptions in coal and nuclear industries that strain the economy and risk brownouts.

In Pennsylvania, these subsidies would follow nearly $9 billion already paid by ratepayers to help the commonwealth's nuclear industry transition from regulated to competitive energy markets.

The deregulation of Pennsylvania's electricity markets in the late 1990s allowed the nuclear industry to receive billions of dollars from ratepayers to recover "stranded costs" related to investments in the commonwealth's nuclear plants. These costs were negotiated amounts based on settlements with Pennsylvania's Public Utility Commission to allow the nuclear industry to prepare and transition to competitive electricity markets.

Enough is enough. Regulatory or governmental interference in well functioning markets does not lead to better outcomes. Pennsylvania's state Legislature should not pick winners and losers by enacting legislation that would create an uneven playing field that subsidizes nuclear generating resources in the commonwealth.

William Ferguson is regional vice president for Calpine Corp.

Florida Court Blocks Push to Break Electricity Monopolies

Florida Electricity Deregulation Ruling highlights the Florida Supreme Court decision blocking a ballot measure on retail choice, preserving utility monopolies for NextEra and Duke Energy, while similar deregulation efforts arise in Virginia and Arizona.

 

Key Points

A high court decision removing a retail choice ballot measure, keeping Florida utility monopolies intact for incumbents.

✅ Petition language deemed misleading for 2020 ballot

✅ Preserves NextEra and Duke Energy market dominance

✅ Similar retail choice pushes in VA and AZ

 

Florida’s top court ruled against a proposed constitutional amendment that would have allowed customers to pick their electricity provider, even as Florida solar incentives face rejection by state leaders, threatening monopolies held by utilities such as NextEra Energy Inc. and Duke Energy Corp.

In a ruling Thursday, the court said the petition’s language is “misleading” and doesn’t comply with requirements to be included on the 2020 ballot, reflecting debates over electricity pricing changes at the federal level. The measure’s sponsor, Citizens for Energy Choice, said the move ends the initiative, even as electricity future advocacy continues nationwide.

“While we were confident in our plan to gather the remaining signatures required, we cannot overcome this last obstacle,” the group’s chair, Alex Patton, noting ongoing energy freedom in the South efforts, said in a statement.

The proposed measure was one of several efforts underway to deregulate U.S. electricity markets, including New York’s review of retail energy markets this year. Earlier this week, two Virginia state lawmakers unveiled a bill to allow residents and businesses to pick their electricity provider, threatening Dominion Energy Inc.’s longstanding local monopoly. And in Arizona, where Arizona Public Service Co. has long reigned, regulators are considering a similar move, while in New England Hydro-Quebec’s export bid has been energized by a court decision.

Huge offshore wind turbine that can power 18,000 homes

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

 

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

 

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

Ontario introduces new fixed COVID-19 hydro rate

Ontario Electricity COVID-19 Recovery Rate sets a fixed price of 12.8 cents/kWh, replacing time-of-use billing and aligning costs across off-peak, mid-peak, and on-peak periods per Ontario Energy Board guidance through Oct. 31.

 

Key Points

A flat 12.8 cents/kWh electricity price in Ontario that temporarily replaces time-of-use rates from June 1 to Oct. 31.

✅ Fixed 12.8 cents/kWh, all hours, June 1 to Oct. 31

✅ Higher than off-peak 10.1, lower than mid/on-peak

✅ Based on Ontario Energy Board average cost

 

Ontario residents will now have to pay a fixed electricity price that is higher than the off-peak hydro rate many in the province have been allowed to pay so far due to the pandemic. 

The announcement, which was made in a news release on Saturday, comes after the Ontario government suspended the normal “time-of-use” billing system on March 24 and as electricity rates are about to change across Ontario. 

The government moved all customers onto the lowest winter rate in response to the pandemic as emergency measures meant more people would be at home during the middle of the day when electricity costs are the highest. 

Now, the government has introduced a new “COVID-19 recovery rate” of 12.8 cents per kilowatt hour at all times of the day. The fixed price will be in place from June 1 to Oct. 31. 

The fixed price is higher than the winter off-peak price, which stood at 10.1 per kilowatt hour. However, it is lower than the mid-peak rate of 14.4 per kilowatt hour and the high-peak rate of 20.8 per kilowatt hour, even though typical bills may rise as fixed pricing ends for many households. 

“Since March 24, 2020, we have invested just over $175 million to deliver emergency rate relief to residential, farm and small business electricity consumers by suspending time-of-use electricity pricing,” Greg Rickford, the minister of energy, northern development and mines, said in a news release. 

“This investment was made to protect the people of Ontario from a marked increase in electricity rates as they did their part by staying home to prevent the further spread of the virus.”

Rickford said that the COVID-19 recovery rate is based on the average cost of electricity set by the Ontario Energy Board. 

“This fixed rate will continue to suspend time-of-use prices in a fiscally responsible manner,” he said. "Consumers will have greater flexibility to use electricity when they need it without paying on-peak and mid-peak prices, and some may benefit from ultra-low electricity rates under new time-of-use options."

How Energy Use Has Evolved Throughout U.S. History

U.S. Energy Transition traces the shift from coal and oil to natural gas, nuclear power, and renewables like wind and solar, driven by efficiency, grid modernization, climate goals, and economic innovation.

 

Key Points

The U.S. Energy Transition is the shift from fossil fuels to cleaner power, driven by tech, policy, and markets.

✅ Shift from coal and oil to gas, nuclear, wind, and solar

✅ Enabled by grid modernization, storage, and efficiency

✅ Aims to cut emissions while ensuring reliability and affordability

 

The evolution of energy use in the United States is a dynamic narrative that reflects technological advancements, economic shifts, environmental awareness, and societal changes over time. From the nation's early reliance on wood and coal to the modern era dominated by oil, natural gas, and renewable sources, the story of energy consumption in the U.S. is a testament to innovation and adaptation.

Early Energy Sources: Wood and Coal

In the early days of U.S. history, energy needs were primarily met through renewable resources such as wood for heating and cooking. As industrialization took hold in the 19th century, coal emerged as a dominant energy source, fueling steam engines and powering factories, railways, and urban growth. The widespread availability of coal spurred economic development and shaped the nation's infrastructure.

The Rise of Petroleum and Natural Gas

The discovery and commercialization of petroleum in the late 19th century transformed the energy landscape once again. Oil quickly became a cornerstone of the U.S. economy, powering transportation, industry, and residential heating, and informing debates about U.S. energy security in policy circles. Concurrently, natural gas emerged as a significant energy source, particularly for heating and electricity generation, as pipelines expanded across the country.

Electricity Revolution

The 20th century witnessed a revolution in electricity generation and consumption, and understanding where electricity comes from helps contextualize how systems evolved. The development of hydroelectric power, spurred by projects like the Hoover Dam and Tennessee Valley Authority, provided clean and renewable energy to millions of Americans. The widespread electrification of rural areas and the proliferation of appliances in homes and businesses transformed daily life and spurred economic growth.

Nuclear Power and Energy Diversification

In the mid-20th century, nuclear power emerged as a promising alternative to fossil fuels, promising abundant energy with minimal greenhouse gas emissions. Despite concerns about safety and waste disposal, nuclear power plants became a significant part of the U.S. energy mix, providing a stable base load of electricity, even as the aging U.S. power grid complicates integration of variable renewables.

Renewable Energy Revolution

In recent decades, the U.S. has seen a growing emphasis on renewable energy sources such as wind, solar, and geothermal power, yet market shocks and high fuel prices alone have not guaranteed a rapid green revolution, prompting broader policy and investment responses. Advances in technology, declining costs, and environmental concerns have driven investments in clean energy infrastructure and policies promoting renewable energy adoption. States like California and Texas lead the nation in wind and solar energy production, demonstrating the feasibility and benefits of transitioning to sustainable energy sources.

Energy Efficiency and Conservation

Alongside shifts in energy sources, improvements in energy efficiency and conservation have played a crucial role in reducing per capita energy consumption and greenhouse gas emissions. Energy-efficient appliances, building codes, and transportation innovations have helped mitigate the environmental impact of energy use while reducing costs for consumers and businesses, and weather and economic factors also influence demand; for example, U.S. power demand fell in 2023 on milder weather, underscoring the interplay between efficiency and usage.

Challenges and Opportunities

Looking ahead, the U.S. faces both challenges and opportunities in its energy future, as recent energy crisis effects ripple across electricity, gas, and EVs alike. Addressing climate change requires further investments in renewable energy, grid modernization, and energy storage technologies. Balancing energy security, affordability, and environmental sustainability remains a complex task that requires collaboration between government, industry, and society.

Conclusion

The evolution of energy use throughout U.S. history reflects a continuous quest for innovation, economic growth, and environmental stewardship. From wood and coal to nuclear power and renewables, each era has brought new challenges and opportunities in meeting the nation's energy needs. As the U.S. transitions towards a cleaner and more sustainable energy future, leveraging technological advancements and embracing policy solutions, amid debates over U.S. energy dominance, will be essential in shaping the next chapter of America's energy story.

IEC reaches settlement on Palestinian electricity debt

IEC-PETL Electricity Agreement streamlines grid management, debt settlement, and bank guarantees, shifting power supply, transmission, and distribution to PETL via IEC-built sub-stations, bolstering energy cooperation, utility billing, and payment assurance in PA areas.

 

Key Points

A 15-year deal transferring PA grid operations to PETL, settling legacy debt, and securing payments with bank guarantees.

✅ NIS 915 million repaid in 48 installments.

✅ PETL assumes distribution, O&M, and sub-station ownership.

✅ 15-year, NIS 2.8b per year supply and services contract.

 

The Palestinian Authority will pay Israel Electric NIS 915 million and take over management of its grid through Palestinian electricity supplier PETL.

The Israel Electric Corporation (IEC) (TASE: ELEC.B22) and Palestinian electricity supplier PETL have signed a draft commercial agreement under which the Palestinian Authority's (PA) debt of almost NIS 1 billion will be repaid. The agreement also transfers actual management of the supply of electricity to Palestinian customers from IEC to the Palestinian electricity authority, enabling consideration of distributed solutions such as a virtual power plant program in future planning.

Up until now, the IEC was unable to actually collect debts for electricity from Palestinian customers, because the connection with them was through the PA. Responsibility for collection will now be exclusively in Palestinian hands, with the PA providing hundreds of millions of shekels in bank guarantees for future debts. The agreement, which is valid for 15 years, amounts to an estimated NIS 2.8 billion a year, as of now.

IEC will sell electricity and related services to PETL through four high-tension sub-stations built by IEC for PETL and through high and low-tension connection points, similar to large interconnector projects like the Lake Erie Connector, for the purpose of distribution and supply of the electricity by PETL or an entity on its behalf to consumers in PA territory. PETL will have sole operational and maintenance responsibility for distribution and supply and ownership of the four sub-stations.

 

NIS 915 million in 48 payments

According to the IEC announcement, the settlement was reached following negotiations following the signing of an agreement in principle in September 2016 by the minister of finance, the government coordinator of activities in the territories, and the Palestinian minister for civilian affairs. The parties reached commercial understandings yesterday that made possible today's signing of the first commercial document of its kind regulating commercial relations - the sales of electricity - between the parties. The agreement will go into effect after it is approved by the IEC board of directors, the Public Utilities Authority (electricity), reflecting regulatory oversight akin to Ontario industrial electricity pricing consultations, and the IDF Chief Electrical Staff Officer. Representatives of IEC, the Ministry of Finance, the Public Utilities Authority (electricity), the government coordinator of activities in the territories, the civilian authority, the PA government, and PETL took part in the negotiations.

The agreement also settles the PA's historical debt to IEC. The PA will begin payment of NIS 915 million in debt for consumption of electricity before September 2016 to IEC Jerusalem District Ltd. in 48 equal installments after the final signing, as stipulated in the agreement in principle signed by the Israeli government and the PA on September 13, 2016.

The PA's debt for electricity amounted to almost NIS 2 billion in 2016. The initial spadework for the current debt settlement was accomplished in that year, after the parties reached understandings on writing off NIS 500 million of the Palestinian debt. The PA paid NIS 600 million in October 2016, and the remainder will be paid now.

It was also reported that an arrangement of securities and guarantees to ensure payment to IEC under the agreement had been settled, including the past debt. IEC will obtain a bank guarantee and a PA guarantee, in addition to the existing collection mechanisms at the company's disposal.

Minister of Finance Moshe Kahlon said, "Signing the commercial agreement is a historic step completing the agreement signed by the governments in September 2016. Strengthening economic cooperation between Israel and the PA is above all an Israeli security interest. The agreement will ensure future payments to the IEC and reinforce its financial position. I congratulate the negotiating teams for the completion of their task."

Minister of National Infrastructure, Energy, and Water Resources Dr. Yuval Steinitz said, "In my meeting last year with Palestinian Prime Minister Rami Hamdallah in Jenin, we agreed that it was necessary to settle the debt and formalize relations between IEC and the PA. The settlement signed today is a breakthrough, both in the measures for payment of the Palestinian debt to IEC and Israel and in arranging future relations to prevent more debts from emerging in the future. With the signing of the agreement, we will be able to make progress with the Palestinians in developing a modern electrical grid, aligning with regional initiatives like the Cyprus electricity highway, according to the model of the sub-station we inaugurated in Jenin."

IEC chairperson Yiftah Ron Tal said, "This is a historic event. In this agreement, IEC is correcting for the first time a historical distortion of accumulated debt without guarantees, ability to collect it, or control over the amount of debt. This anchor agreement not only constitutes an unprecedented financial achievement; it also constitutes an important milestone in regulating electricity commercial relations between the Israeli and Palestinian electric companies, comparable to cross-border efforts such as the Ireland-France interconnector in Europe."
