Ameresco Completes Fourth Renewable EPC Project with Hoosier Energy

US Shift From Coal to Renewables accelerates as natural gas, solar, and wind power gain market share, driven by the Paris climate agreement, clean energy mandates, smart grid upgrades, and energy efficiency.

Key Points

An industry trend where power producers replace coal with natural gas, solar, and wind to meet clean energy goals.

✅ Shareholders and customers demand cleaner power portfolios

✅ Natural gas, solar, and wind outcompete coal on cost and risk

✅ Smart grid and efficiency investments reduce emissions further

President Trump once again promised to revive the U.S. coal industry when he announced his intention to withdraw the U.S. from the Paris climate agreement.

But that reversal seems as unlikely as ever as electric power producers, the biggest consumers of coal in the U.S., continue to shift to natural gas and renewable energy sources like solar and wind power. In 2016, natural gas became the leading fuel for U.S. electricity generation for the first time, responsible for 33.8% of the output, compared with 30.4% for coal, according to the U.S. Energy Information Administration, even as coal-fired generation was projected to rise in 2021 in the short term.

Nick Akins, the CEO of American Electric Power, one of the largest utilities in the U.S., says the preference for gas, renewables and energy efficiency, will only grow in response to increasing demands from shareholders and customers for cleaner energy, regardless of changes in national energy policy.

With 5.4 million customers in 11 states, AEP plans to spend $1.5 billion on renewable energy from 2017 through 2019, and $13 billion on transmission and distribution improvements, including new “smart” technologies that will make the grid more resilient and efficient, AEP says.

We spoke with Akins on Thursday, just after Trump’s announcement. The transcript is edited for length and clarity.

What do you think of Trump’s decision to pull the U.S. from the climate agreement?

I don’t think it’s unexpected. He obviously made the point that he’s willing to renegotiate or have further dialogue about it. That’s a good sign. From our perspective, we’re going to continue along the path we’re already on toward a cleaner energy economy.

AEP and the U.S. electric power industry in general have been moving away from coal in favor of natural gas and renewable energy. Will this decision by the Trump administration have any impact on that trend?

If you look at our resource plans in all of the states we serve, they are focused on renewables, natural gas and transmission, as declining returns from coal generation pressure investment choices across the industry. And big-data analytics improves the efficiency of the grid, so energy efficiency is obviously a key component, as Americans use less electricity overall.

Our carbon dioxide emissions in 2016 were 44% below 2000 levels, and that progress will continue with the additions of more renewables, energy efficiency and natural gas.

So, you don’t see coal making a comeback at AEP or other utilities?

No, I don’t think so. … You wouldn’t make a decision (to build a coal power plant) at this point because it’s heavily capital-intensive, and involves a longer-term process and risk to build. And, of course, you can add renewables that are very efficient and natural gas that’s efficient and much less expensive and risky, in terms of construction and operation.

Do you plan to close any more coal-powered plants soon? 

I suspect we’ll see some more retirements in the future, with coal and nuclear closures test just transition in many communities, and as we progress towards that cleaner energy economy, and consider the expectations of our customers and shareholders for us to mitigate risk, you’ll continue to see that happen.

But on the other hand, I want to make sure there’s an understanding that coal will remain a part of the portfolio, even though in rare cases new coal plants are still being built where options are limited, but it will be of a lesser degree because of these other resources that are available to us now that weren’t available to us just a few years ago.

Do you find yourself under more or less pressure from customers and shareholders to move to cleaner forms of energy?

I think there’s more pressure. Investors are looking for the sustainability of the company going forward and mitigation of risks … From a customer standpoint, we have some large customers interested in moving into our service territory who are looking for cleaner energy, and want to know if we’re focused on that. Some of them want to be supplied entirely by those clean sources. So, we’re clearly responding to our customers’ and our shareholders’ expectations.

What’s the solution for workers at coal mines and coal power plants who have lost their jobs?

Certainly, the skill sets of employees in mining and around machinery are transferable to other areas of manufacturing, like aerospace and defense. So, we’re really focusing on economic-development efforts in our service territories … particularly in the coal states … to bring coal miners back to work, not necessarily in coal mines but certainly (in manufacturing).

Uber Elevate eVTOL Batteries enable electric air taxis with advanced energy storage, lithium-ion cell quality, safety engineering, and zero-emissions performance for urban air mobility, ride-hailing aviation, and scalable battery pack development.

Key Points

Battery systems for Uber's electric air taxis, maximizing energy density, safety, and cycle life for urban air mobility.

✅ Ex-Tesla battery leader guides pack design and cell quality

✅ All-electric eVTOL targets zero-emissions urban air mobility

✅ Focus on safety, energy density, fast charge, and lifecycle

Celina Mikolajczak, a senior manager for battery pack development at Tesla, has been hired by Uber to help the ride-hail company’s “flying car” project get off the ground. It’s an important hire because it signals that Uber plans to get more involved in the engineering aspects of this outlandish-sounding project.

For six years, Mikolajczak served as senior manager and technical lead for battery technology, cell quality, and materials analysis. She worked with Tesla’s suppliers, tested the car company’s lithium-ion batteries for long-term use as the age of electric cars accelerates, oversaw quality assurance, and conducted “failure analysis” to drive battery cell production and design improvements. In other words, Mikolajczak was in charge of making sure the most crucial component in Tesla’s entire assembly line was top of the line.

Now she works for Uber — and not just for Uber, but for Uber Elevate, the absurdly ambitious air taxi service that hinges on the successful development of electric vertical take-off and landing (eVTOL) vehicles. There are practically zero electric planes in service today, and definitely none being used in a commercial ride-hail service. The hurdles to getting this type of service off the ground are enormous.

Her title at Uber is director of engineering and energy storage systems, and today marks her first week on the job. She joins Mark Moore, the former chief technologist for on-demand mobility at NASA’s Langley Research Center, who joined Uber almost a year ago to help lend a professional appearance to Elevate. Both serve under Jeff Holden, Uber’s head of product, who oversees the air taxi project.

Uber first introduced its plan to bring ride-sharing to the skies in a white paper last year. At the time, Uber said it wasn’t going to build its own eVTOL aircraft, but stood ready to “contribute to the nascent but growing VTOL ecosystem and to start to play whatever role is most helpful to accelerate this industry’s development.”

Instead, Uber said it would be partnering with a handful of aircraft manufacturers, real estate firms, and government regulators to better its chances of developing a fully functional, on-demand flying taxi service. It held a day-long conference on the project in Dallas in April, and plans to convene another one later this year in Los Angeles. In 2020, Uber says its aerial service will take off in three cities: LA, Dallas-Fort Worth, and Dubai.

UBER’S TAKING A MORE PROMINENT ROLE

Now, Uber’s taking a more prominent role in the design and manufacturing of its fleet of air taxis, which signals a stronger commitment to making this a reality — and also more of a responsibility if things eventually go south, as setbacks like Eviation's collapse underscore.

Perhaps most ambitiously, Uber says the aircraft it plans to use (but, importantly, do not exist yet) will run on pure battery-electric power, and not any hybrid of gasoline and electricity. Most of the companies exploring eVTOL admit that battery’s today aren’t light enough or powerful enough to sustain flights longer than just a few minutes, but many believe that battery technology will eventually catch up, with Elon Musk suggesting a three-year timeline for cheaper, more powerful cells.

Uber believes that in order to sustain a massive-scale new form of transportation, it will need to commit to an all-electric, zero-operational emissions approach from the start, even as potential constraints threaten the EV boom overall. And since the technology isn’t where it needs to be yet, the ride-hail company is taking a more prominent role in the development of the battery pack for its air taxi vehicles. Mikolajczak certainly has her work cut out for her.

PEI Electric Vehicle Incentives aim to boost EV adoption through subsidies and rebates, advocated by Renewable Transport PEI, with MLAs engagement, modeling Norway's approach, offsetting HST gaps, and making electric cars more competitive for Islanders.

Key Points

PEI Electric Vehicle Incentives are proposed subsidies and rebates to make EVs affordable and competitive for Islanders.

✅ Targets EV adoption with rebates up to 20 percent

✅ Modeled on Norway policies; offsets prior HST-era gaps

✅ Backed by Renewable Transport PEI engaging MLAs

Noah Ellis, assistant director of Renewable Transport P.E.I., is asking government to introduce incentives for Islanders to buy electric cars, as cost barriers remain a key hurdle for many.

RTPEI is a group composed of high school students at Colonel Gray going into their final year."We wanted to give back and contribute to our community and our country and we thought this would be a good way to do so," Ellis told Compass.

Meeting with government

"We want to see the government bring in incentives for electric vehicles, similar to New Brunswick's rebate program, because it would make them more competitive with their gasoline counterparts," Ellis said.

'We wanted to give back and contribute to our community … we thought this would be a good way to do so.'— Noah Ellis

Ellis said the group has spoken with opposition MLAs and is meeting with cabinet ministers soon to discuss subsidies for Islanders to buy electric cars, noting that Atlantic Canadians are less inclined to buy EVs compared to the rest of the country.

He referred to Norway as a prime example for the province to model potential incentives, even as Labrador's EV infrastructure gaps underscore regional challenges — a country that, as of last year, announced nearly 40 per cent of the nation's newly registered passenger vehicles as electric powered.

'Incentives that are fiscally responsible'

Ellis said they group isn't looking for anything less than a 20 per cent incentive on electric vehicles — 10 per cent higher than the provinces cancelled hybrid car tax rebate that existed prior to HST.

"Electric vehicle incentives do work we just have to work with economists and environmentalists, and address critics of EV subsidies, to find the right balance of incentives that are fiscally responsible for the province but will also be effective," Ellis said.

California Natural Gas Plant Rethink signals a shift toward clean energy, renewables, distributed solar, battery storage, and grid modernization as LADWP and regulators pause repowering plans amid an electricity oversupply and rising ratepayer costs.

Key Points

California pauses new gas plants to assess renewables, storage, and grid solutions for reliability.

✅ LADWP delays $2.2B gas repowers to study clean alternatives

✅ CEC weighs halting Oxnard plant amid grid oversupply

✅ Distributed solar, batteries, demand response boost reliability

California energy officials are, for the first time, rethinking plans to build expensive natural gas power plants in the face of an electricity glut and growing use of cleaner and cheaper energy alternatives.

The Los Angeles Department of Water and Power announced Tuesday that it has put a hold on a $2.2-billion plan to rebuild several old natural gas power plants while it studies clean energy alternatives to meet electricity demands. And the California Energy Commission may decide as early as Thursday to halt a natural gas project in Ventura County.

The scrutiny comes after an investigation found that the state is operating with an oversupply of electricity, driven largely by the construction of gas-fueled generating plants, leading to higher rates as regulators consider a rate overhaul to clean the grid. The state’s power plants are on track to be able to produce at least 21% more electricity than needed by 2020, according to the Times report.

Californians are footing a $40-billion annual bill while using less electricity, paying $6.8 billion more than they did in 2008 when power use in the state was at its all-time high. Electricity consumption has since fallen and remained largely flat.

Utilities in California have been on a years-long building binge, adding new natural gas plants even as the nation’s electricity system has undergone significant change, including consumer choice reforms that are reshaping the market.

Where utilities once delivered all electrical services from huge power plants along miles of transmission lines, the industry now must consider power delivered to the electric grid not only from its own sources, but also from solar systems and batteries at homes and businesses.

At the same time, utilities have been aggressively upgrading or rebuilding their aging natural gas plants — a move critics have said is unnecessary because consumers are using less power and clean energy technology is making those plants obsolete.

The DWP and energy commission moves involve as many as seven natural gas plant projects proposed for Southern California, despite warnings about a looming shortage if capacity is retired too fast, from Oxnard to Carlsbad, at a cost of more than $6 billion.

Reiko Kerr, the DWP’s senior assistant general manager of power systems, said given the changes in the energy world, the assessment is necessary to protect ratepayer dollars and the environment.

“The whole utility paradigm has shifted,” Kerr said in an interview. “We really are doing our ratepayers a disservice by not considering all viable options.

“We’re just looking at everything,” she said. “What can help us solve this reliability, renewable and greenhouse gas challenge that we all have?”

State and local governments have felt a heightened sense of urgency to deal with climate change after President Trump decided last week to withdraw the United States from the Paris climate accord.

California already has mandated that at least 50% of the state’s electricity come from clean energy sources by 2030. Senate leader Kevin de León (D-Los Angeles) wants to increase that to 100% by 2045.

Building or overhauling natural gas plants throughout Southern California, environmentalists argue, isn’t helping achieve those goals, even as some contend the state can't keep the lights on without gas during the transition.

The DWP’s move to delay plans for the fossil fuel plants, which seemed all but set to be built, came as a surprise to clean-energy advocates, who hailed the decision.

“This is a great first step toward smart energy investments that save customers money, ensure the lights stay on and protect our health and environment,” Graciela Geyer of the Sierra Club said.

The environmental group said that if the utility had moved ahead with the $2.2-billion investment in repowering natural gas plants, it “would have blown an irreparable hole in the city and the state’s hopes to achieve 100% generation” from clean energy sources.

Angela Johnson Meszaros, attorney at EarthJustice, said in a statement: "As our city struggles with the worst smog we’ve seen in years, we appreciate that LADWP is taking some much-needed time to reassess its plans to build fossil fuel power plants. We look forward to the day that LADWP announces that we are going to power our city with 100% clean energy.”

The gas-fired generating units slated for demolition and rebuilding are at the Scattergood, Haynes and Harbor electricity plants, which range from 34 to 67 years old.

As a group, the three plants have generated less than 20% of their combined capacity since 2001. The Harbor facility has operated on the low end at just 7%, while Haynes ran on the high end at 22%.

“The old model, the old legacy clunkers, won’t get us into the future we want,” DWP’s Kerr said.

DWP staff members told the utility’s’ commissioners Tuesday that their analysis of possible alternatives would be completed no later than early 2018.

Separately, the California Energy Commission this week is evaluating whether to halt a natural gas project in Ventura County after the state’s electric grid operator offered to conduct a study of clean energy alternatives to the roughly $250-million project on Mandalay Bay in Oxnard.

An energy commission committee has been deliberating since a hearing Monday during which Southern California Edison and the project’s developer, NRG Energy, argued that a study is simply a delay tactic that probably would kill a project needed to ensure reliable electric service and to avoid blackouts during peak demand.

The California Independent System Operator, which runs the state’s electric grid, told the energy commission that it would take three to four weeks to conduct its study on alternatives to the Oxnard natural gas project.

“Here we have an actual offer by the ISO to do such an analysis,” Ellison Folk, a lawyer representing the city of Oxnard, told the energy commission as she pushed for the study. “Its view that this is an analysis worth doing is something worth taking seriously.”

Energy commission members reviewing the study proposal are scheduled to meet again Thursday to consider the offer.

The board of governors for the California Independent System Operator made the unusual offer at its May 1 meeting to conduct a eleventh-hour study of clean-energy alternatives to building a new natural gas plant.

“If we’re going to be moving forward with a gas plant at this time, in this juncture, in the context of everything that’s going on, not evaluating other alternatives that are viable, noncombustion alternatives, is a missed opportunity,” Angelina Galetiva. a commission board member, said during the May 1 meeting.

Vehicle-to-Grid (V2G) enables bidirectional charging, letting EV batteries supply smart grid services to large buildings, support renewable energy integration, reduce battery degradation, and optimize demand response for efficient, resilient power management.

Key Points

Vehicle-to-Grid (V2G) is bidirectional EV charging that feeds the grid and buildings while protecting battery health.

✅ Uses idle EVs to power buildings and support renewables

✅ Smart algorithms minimize lithium-ion battery degradation

✅ Provides grid services, demand response, and peak shaving

Stored energy from electric vehicles (EVs) can be used to power large buildings -- creating new possibilities for the future of smart, renewable energy -- thanks to ground-breaking battery research from WMG at the University of Warwick.

Dr Kotub Uddin, with colleagues from WMG's Energy and Electrical Systems group and Jaguar Land Rover, has demonstrated that vehicle-to-grid (V2G) technology can be intelligently utilised to take enough energy from idle EV batteries to be pumped into the grid and power buildings -- without damaging the batteries.

This new research into the potentials of V2G shows that it could actually improve vehicle battery life by around ten percent over a year.

For two years, Dr Uddin's team analysed some of the world's most advanced lithium ion batteries used in commercially available EVs -- and created one of the most accurate battery degradation models existing in the public domain -- to predict battery capacity and power fade over time, under various ageing acceleration factors -- including temperature, state of charge, current and depth of discharge.

Using this validated degradation model, Dr Uddin developed a 'smart grid' algorithm, which supports grid coordination and intelligently calculates how much energy a vehicle requires to carry out daily journeys, and -- crucially -- how much energy can be taken from its battery without negatively affecting it, or even improving its longevity.

The researchers used their 'smart grid' algorithm to see if they could power WMG's International Digital Laboratory -- a large, busy building which contains a 100-seater auditorium, two electrical laboratories, teaching laboratories, meeting rooms, and houses approximately 360 staff -- with vehicle-to-building charging from EVs parked on the University of Warwick campus.

They worked out that the number of EVs parked on the campus (around 2.1% of cars, in line with the UK market share of EVs) could spare the energy to power this building, acting as capacity on wheels for electricity networks -- and that in doing so, capacity fade in participant EV batteries would be reduced by up to 9.1%, and power fade by up to 12.1% over a year.

It has previously been thought that extracting energy from EVs with V2G technology causes their lithium ion batteries to degrade more rapidly.

Dr Uddin's group (along with collaborators from Jaguar Land Rover) have proved, however, that battery degradation is more complex -- and this complexity, in operation, can be exploited to improve a battery's lifetime.

Given that battery degradation is dependent on calendar age, capacity throughput, temperature, state of charge, current and depth of discharge, V2G is an effective tool that can be used to optimise a battery's conditions such that degradation is minimised. Hence, taking excess energy from an idle EV to power the grid actually keeps the battery healthier for longer.

Dr Uddin commented on the research:

"These findings reinforce the attractiveness of vehicle-to-grid technologies to automotive Original Equipment Manufacturers: not only is vehicle-to-grid an effective solution for grid support -- and subsequently a tidy revenue stream -- but we have shown that there is a real possibility of extending the lifetime of traction batteries in tandem.

"The results are also appealing to policy makers interested in grid decarbonisation and addressing grid challenges from rising EVs across power systems."

The research, 'On the possibility of extending the lifetime of lithium-ion batteries through optimal V2G facilitated by an integrated vehicle and smart-grid system' is published in Energy.

It was funded by the Engineering and Physical Sciences Research Council and the WMG centre High Value Manufacturing Catapult, in partnership with Jaguar Land Rover.

Ireland Wind and Solar Share 2022 highlights IEA projections of over 33% electricity generation from renewables, with variable renewable energy growth, capacity targets, EU policy shifts, and investments accelerating wind and solar deployment.

Key Points

IEA forecasts wind and solar to exceed 33% of Ireland's electricity by 2022, second in variable renewables after Denmark.

✅ IEA expects Ireland to surpass 33% wind and solar by 2022

✅ Denmark leads at ~70%; Germany and UK exceed 25%

✅ Investments and capacity targets drive renewable growth

The share of wind and solar in total electricity generation in Ireland is expected to exceed 33pc by 2022, according to the 'Renewables 2017' report from the International Energy Agency (IEA).

Among the findings, the report says that Denmark is on course to be the world leader in the variable renewable energy sector, with 70pc of its electricity generation expected to come from wind and solar renewables by 2022.

The Nordic country will be followed by Ireland, Germany and the UK, all of which are expected see their share of wind and solar energy in total electricity generation exceed 25pc, according to the IEA report.

In a move to increase the level of wind generation in Ireland, the Government-controlled Ireland Strategic Investment Fund (Isif) teamed up with German solar and wind park operator Capital Stage in January to invest €140m in 20 solar parks in Ireland.

#google#

The parks are being developed by Dublin-based Power Capital, and it marks the first time that Isif has committed to financing solar park developments in this country.

Globally, renewables accounted for almost two-thirds of net new power capacity, with nearly 165 gigawatts (GW) coming online in 2016.

This was a record year that was largely driven by a booming solar market in China and around the world.

In 2016 solar capacity around the world grew by 50pc, reaching over 74 GW, with China's solar PV accounting for almost half of this expansion. In another first, solar energy additions rose faster than any other fuel, surpassing the net growth in coal, the IEA report found.

China alone is responsible for over two-fifths of global renewable capacity growth, which, according to the IEA, is largely driven by concerns about the country's air pollution and capacity targets.

The Asian giant is also the world market leader in hydropower, bioenergy for electricity and heat, and electric vehicles, the IEA report said. In 2016 the United States remained the second largest growth market for renewables.

However, with US President Donald Trump withdrawing the country from the Paris Agreement on climate change, the country's commitment to renewable energy faces policy uncertainty.

Meanwhile, India continues to grow its renewable electricity capacity, and by 2022, the country is expected to more than double its current renewable electricity capacity, according to the IEA. For the first time, this growth over the forecast period (2016-2022) is higher compared with the European Union, according to the report.

Meanwhile in the EU, renewable energy growth over the forecast period is 40pc lower compared with the previous five-year period.

The low forecast in respect of the EU is based on a number of factors, the IEA said, including weaker electricity demand, overcapacity, and limited visibility on forthcoming auction capacity volumes in some markets.

Overall, the Government has committed to generating 40pc of its electricity from renewable energy sources by 2020.

That target is set to be missed, which would see the Government eventually having to fork out hundreds of millions of euro for carbon credits.

Later this year, Ireland will host Europe's biggest summit on Climate Innovation, during which over 50 nationwide events and initiatives will be held.
