The city of Seattle and Nissan North America said they will work together to promote the development of an electric car-charging network in Seattle.
Nissan plans to introduce plug-in electric vehicles in 2010 in Seattle, along with other markets including Oregon and Tennessee, and mass market them globally two years later.
The third-largest Japanese automaker, after Toyota and Honda, said its five-passenger plug-in hatchback runs about 100 miles (160 kilometers) on a single charge and uses a standard 220-volt outlet to recharge.
"From light rail to street cars to electric vehicles, we're reducing the impact of transportation on our climate," Mayor Greg Nickels said.
Katherine Zachary, a Nissan spokeswoman, said it takes about four hours to recharge the car and the company is working to promote technology to cut that time down to about 26 minutes.
She declined to say how many vehicles the company would initially produce, but said they will also be sold in San Diego and Sonoma County, Calif., and Tucson, Ariz.
The Washington Legislature passed a measure that provides tax breaks on sales of electric car batteries or electric charging infrastructure.
"We were attempting to establish an expectation that cities and counties would permit the infrastructure necessary to support electric cars," said Rep. Deborah Eddy, D-Kirkland, the bill's sponsor. "It sends a signal to electric car manufacturers that we want those cars here."
The bill, which awaits Gov. Chris Gregoire's signature, also requires the state to install charging stations in the state's fleet parking and maintenance facilities by 2015. And it sets up a pilot project along Interstate 5, from Olympia to Seattle, to offer electric car drivers outlets to recharge and places to swap out batteries.
Charging outlets are already available to the public in some Washington areas, such as Lacey and parts of King County.
Nissan said it would team up with businesses and nonprofits to promote an electric charging network in Seattle.
Seattle officials said they would help consumers get permits to install home charging stations, and may also consider incentives for those who own electric cars.
Besides Nissan, General Motors Corp., Ford Motor Co. and other automakers are planning electric vehicles.
Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.
Key Points
Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.
✅ Balances variable renewables with dispatchable generation
✅ Rewards flexibility via capacity markets and ancillary services
✅ Enhances grid stability for critical loads during low demand
The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.
In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."
Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.
"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.
"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.
"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."
In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.
"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.
"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."
Nighttime Thermoelectric Generator converts radiative cooling into renewable energy, leveraging outer space cold; a Stanford-UCLA prototype complements solar, serving off-grid loads with low-power output during peak evening demand, using simple materials on a rooftop.
Key Points
A device converting nighttime radiative cooling into electricity, complementing solar for low-power evening needs.
✅ Uses thermocouples to convert temperature gradients to voltage.
✅ Exploits radiative cooling to outer space for night power.
✅ Complements solar; low-cost parts suit off-grid applications.
Two years ago, one freezing December night on a California rooftop, a tiny light shone weakly with a little help from the freezing night air. It wasn't a very bright glow. But it was enough to demonstrate the possibility of generating renewable power after the Sun goes down.
Working with Stanford University engineers Wei Li and Shanhui Fan, University of California Los Angeles materials scientist Aaswath Raman put together a device that produces a voltage by channelling the day's residual warmth into cooling air, effectively generating electricity from thin air with passive heat exchange.
"Our work highlights the many remaining opportunities for energy by taking advantage of the cold of outer space as a renewable energy resource," says Raman.
"We think this forms the basis of a complementary technology to solar. While the power output will always be substantially lower, it can operate at hours when solar cells cannot."
For all the merits of solar energy, it's just not a 24-7 source of power, although research into nighttime solar cells suggests new possibilities for after-dark generation. Sure, we can store it in a giant battery or use it to pump water up into a reservoir for later, but until we have more economical solutions, nighttime is going to be a quiet time for renewable solar power.
Most of us return home from work as the Sun is setting, and that's when energy demands spike to meet our needs for heating, cooking, entertaining, and lighting.
Unfortunately, we often turn to fossil fuels to make up the shortfall. For those living off the grid, it could require limiting options and going without a few luxuries.
Shanhui Fan understands the need for a night time renewable power source well. He's worked on a number of similar devices, including carbon nanotube generators that scavenge ambient energy, and a recent piece of technology that flipped photovoltaics on its head by squeezing electricity from the glow of heat radiating out of the planet's Sun-warmed surface.
While that clever item relied on the optical qualities of a warm object, this alternative device makes use of the good old thermoelectric effect, similar to thin-film waste-heat harvesting approaches now explored.
Using a material called a thermocouple, engineers can convert a change in temperature into a difference in voltage, effectively turning thermal energy into electricity with a measurable voltage. This demands something relatively toasty on one side and a place for that heat energy to escape to on the other.
The theory is the easy part – the real challenge is in arranging the right thermoelectric materials in such a way that they'll generate a voltage from our cooling surrounds that makes it worthwhile.
To keep costs down, the team used simple, off-the-shelf items that pretty much any of us could easily get our hands on.
They put together a cheap thermoelectric generator and linked it with a black aluminium disk to shed heat in the night air as it faced the sky. The generator was placed inside a polystyrene enclosure sealed with a window transparent to infrared light, and linked to a single tiny LED.
For six hours one evening, the box was left to cool on a roof-top in Stanford as the temperature fell just below freezing. As the heat flowed from the ground into the sky, the small generator produced just enough current to make the light flicker to life.
At its best, the device generated around 0.8 milliwatts of power, corresponding to 25 milliwatts of power per square metre.
That might just be enough to keep a hearing aid working. String several together and you might just be able to keep your cat amused with a simple laser pointer. So we're not talking massive amounts of power.
But as far as prototypes go, it's a fantastic starting point. The team suggests that with the right tweaks and the right conditions, 500 milliwatts per square metre isn't out of the question.
"Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed," says Raman.
While we search for big, bright ideas to drive the revolution for renewables, it's important to make sure we don't let the smaller, simpler solutions like these slip away quietly into the night.
Sidi Mansour Wind Farm Tunisia will deliver 30 MW as an IPP, backed by UPC Renewables and CFM, under a STEG PPA, supporting 2030 renewable energy targets, grid connection, job creation, and CO2 emissions reduction.
Key Points
A 30 MW wind IPP by UPC and CFM in Sidi Mansour, supplying STEG and advancing Tunisia's 2030 renewable target.
✅ 30 MW capacity under STEG PPA, first wind IPP in Tunisia
✅ Co-developed by UPC Renewables and Climate Fund Managers
✅ Cuts CO2 by up to 56,645 t and creates about 100 jobs
UPC Renewables (UPC) and the Climate Fund Managers (CFM) have partnered to develop a 30 megawatt wind farm in Sidi Mansour, Tunisia, which, amid regional wind expansion efforts, will help the country meet its 30% renewable energy target by 2030.
Tunisia announced the launch of its solar energy plan in 2016, with projects like the 10 MW Tunisian solar park aiming to increase the role of renewables in its electricity generation mix ten-fold to 30%,
This Sidi Mansour Project will help Tunisia meet its goals, reducing its reliance on imported fossil fuels and, mirroring 90 MW Spanish wind build milestones, demonstrating to the world that it is serious about further development of renewable energy investment.

This project will also be among the country’s first Independent Power Producers (IPP). CFM is acting as sponsor, financial adviser and co-developer on the project, in a landscape shaped by IRENA-ADFD funding in developing countries, while UPC will lead the development with its local team. The team will be in charge of permitting, grid connection, land securitisation, assessment of wind resources, contract procurement and engineering.
UPC was selected under the “Authorisation Scheme” tender for the project in 2016, similar to utility-scale developments like a 450 MW U.S. wind farm, and promptly signed a power purchase agreement with Société Tunisienne Electricité et du Gaz (STEG).
Brian Caffyn, chairman of UPC Group, said: “We can start the construction of the Sidi Mansour wind farm in 2020, helping stimulate the Tunisian economy, create local jobs and a social plan for local communities while respecting international environmental protection guidelines.”
Sebastian Surie, CFM’s regional head of Africa, added: “CFM is thrilled to partner with a leading wind developer in the Sidi Mansour Wind Project to assist Tunisia in meeting its renewable energy goals. As potentially the first Wind IPP in Tunisia, this Project will be a testament to how CI1’s full life-cycle financing solution can unlock investment in renewable energy in new markets, as seen in an Irish offshore wind project globally.”
The project will not only provide electricity, but also reduce CO2 emissions by up to 56,645 tonnes and create some 100 new jobs.

Tunisia’s first power station, “Chams Enfidha,” inaugurated at the beginning of July, has a capacity of one megawatt, with an estimated cost of 3.3 million dinars ($1.18 million). The state invested 2.3 million dinars into the project ($820,000), with the remaining 1 million dinars ($360,000) provided by a private investor.
Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.
Key Points
Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.
✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average
✅ Methane and nitrous oxide surged, elevating total radiative forcing
✅ Concentrations differ from emissions; sinks absorb about half
The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.
Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.
Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.
The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.
The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.
Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.
Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.
This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.
The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.
Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.
Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.
Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.
What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.
There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.
"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.
"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.
The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.
Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.
Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.
Belarus Nuclear Power Infrastructure Review evaluates IAEA INIR Phase 3 readiness at Ostrovets NPP, VVER-1200 reactors, legal and regulatory framework, commissioning, safety, emergency preparedness, and energy diversification in a low-carbon program.
Key Points
An IAEA INIR Phase 3 assessment of Belarus readiness to commission and operate the Ostrovets NPP with VVER-1200 units.
✅ Reviews legal, regulatory, and institutional arrangements
✅ Confirms Phase 3 readiness for safe commissioning and operation
✅ Highlights good practices in peer reviews and emergency planning
An International Atomic Energy Agency (IAEA) team of experts today concluded a 12-day mission to Belarus to review its infrastructure development for a nuclear power programme. The Integrated Nuclear Infrastructure Review (INIR) was carried out at the invitation of the Government of Belarus.
Belarus, seeking to diversify its energy production with a reliable low-carbon source, and aware of the benefits of energy storage for grid flexibility, is building its first nuclear power plant (NPP) at the Ostrovets site, about 130 km north-west of the capital Minsk. The country has engaged with the Russian Federation to construct and commission two VVER-1200 pressurised water reactors at this site and expects the first unit to be connected to the grid this year.
The INIR mission reviewed the status of nuclear infrastructure development using the Phase 3 conditions of the IAEA’s Milestones Approach. The Ministry of Energy of Belarus hosted the mission.
The INIR team said Belarus is close to completing the required nuclear power infrastructure for starting the operation of its first NPP. The team made recommendations and suggestions aimed at assisting Belarus in making further progress in its readiness to commission and operate it, including planning for integration with variable renewables, as advances in new wind turbines are being deployed elsewhere to strengthen the overall energy mix.
“This mission marks an important step for Belarus in its preparations for the introduction of nuclear power,” said team leader Milko Kovachev, Head of the IAEA’s Nuclear Infrastructure Development Section. “We met well-prepared, motivated and competent professionals ready to openly discuss all infrastructure issues. The team saw a clear drive to meet the objectives of the programme and deliver benefits to the Belarusian people, such as supporting the country’s economic development, including growth in EV battery manufacturing sectors.”
The team comprised one expert from Algeria and two experts from the United Kingdom, as well as seven IAEA staff. It reviewed the status of 19 nuclear infrastructure issues using the IAEA evaluation methodology for Phase 3 of the Milestones Approach, noting that regional integration via an electricity highway can shape planning assumptions as well. It was the second INIR mission to Belarus, who hosted a mission covering Phases 1 and 2 in 2012.
Prior to the latest mission, Belarus prepared a Self-Evaluation Report covering all infrastructure issues and submitted the report and supporting documents to the IAEA.
The team highlighted areas where further actions would benefit Belarus, including the need to improve institutional arrangements and the legal and regulatory framework, drawing on international examples of streamlined licensing for advanced reactors to ensure a stable and predictable environment for the programme; and to finalize the remaining arrangements needed for sustainable operation of the nuclear power plant.
The team also identified good practices that would benefit other countries developing nuclear power in the areas of programme and project coordination, the use of independent peer reviews, cooperation with regulators from other countries, engagement with international stakeholders and emergency preparedness, and awareness of regional initiatives such as new electricity interconnectors that can enhance system resilience.
Mikhail Chudakov, IAEA Deputy Director General and Head of the Department of Nuclear Energy attended the Mission’s closing meeting. “Developing the infrastructure required for a nuclear power programme requires significant financial and human resources, and long lead times for preparation and the approval of major transmission projects that support clean power flows, and the construction activities,” he said. “Belarus has made commendable progress since the decision to launch a nuclear power programme 10 years ago.”
“Hosting the INIR mission, Belarus demonstrated its transparency and genuine interest to receive an objective professional assessment of the readiness of its nuclear power infrastructure for the commissioning of the country’s first nuclear power plant,” said Mikhail Mikhadyuk, Deputy Minister of Energy of the Republic of Belarus. ”The recommendations and suggestions we received will be an important guidance for our continuous efforts aimed at ensuring the highest level of safety and reliability of the Belarusian NPP."
Hong Kong Typhoon Mangkhut Power Outages strain households with blackouts, electricity disruption, and humid heat, impacting Tin Ping Estate in Sheung Shui and outlying islands; contractor-led restoration faces fines for delays and infrastructure repairs.
Key Points
They are blackout events after Typhoon Mangkhut, bringing heat stress, food spoilage, and delayed power restoration.
✅ 16 floors in Tin Ping Estate lost power after meter room blast.
✅ Contractor faces HK$100,000 daily fines for late restoration.
✅ Kat O and Ap Chau families remain off-grid in humid heat.
Nearly 600 Hong Kong families are still sweltering under the summer heat and facing dark nights without electricity after Typhoon Mangkhut cut off power supply to areas, echoing mass power outages seen elsewhere.
At Sheung Shui’s Tin Ping Estate in the New Territories, 384 families were still without power, a situation similar to the LA-area blackout that left many without service. They were told on Tuesday that a contractor would rectify the situation by Friday, or be fined HK$100,000 for each day of delay.
In remote areas such as outlying islets Kat O and Ap Chau, there were some 200 families still without electricity, similar to Tennessee storm outages affecting rural communities.
The power outage at Tin Ping Estate affected 16 floors – from the 11th to 26th – in Tin Cheung House after a blast from the meter room on the 15th floor was heard at about 5pm on Sunday, and authorities urged residents to follow storm electrical safety tips during repairs.
“I was sitting on the sofa when I heard a loud bang,” said Lee Sau-king, 61, whose flat was next to the meter room. “I was so scared that my hands kept trembling.”
While the block’s common areas and lifts were not affected, flats on the 16 floors encountered blackouts.
As her fridge was out of power, Lee had to throw away all the food she had stocked up for the typhoon. With the freezer not functioning, her stored dried seafood became soaked and she had to dry them outside the window when the storm passed.
Daily maximum temperatures rose back to 30 degrees Celsius after the typhoon, and nights became unbearably humid, as utilities worldwide pursue utility climate adaptation to maintain reliability. “It’s too hot here. I can’t sleep at all,” Lee said.
