Life-cycle assessments are ways to gauge the impact of any product or process. What is the cost of a system over a defined period of time? Life-cycle assessments are really important as we consider the transition to renewable energy sources, especially as we share insights into a zero emissions future with newbies or cynics.

Life-cycle assessments provide an exhaustive overview of the upstream (material sourcing and delivery) and downstream (product distribution, use, and disposal) impacts associated with any given system. Originally designed to focus on environmental impacts by scientists, they now have been extended to examine social and economic impacts, sometimes called life-cycle costing, by policymakers and decision-makers. The most comprehensive evaluations begin with the extraction of raw material; move to the various steps of production, implementation, and operation; and extend all the way to the energy use of carriers to perform work.

Life-cycle analysis considers both upfront cost of production and incremental costs of operation and depreciation. As a data-intensive methodology, it incorporates all inputs and outputs, requires detailed information, and is organized into databases known as life-cycle inventories.

What Do the Scientists Say about Energy Resources & their Life-Cycle Assessments?

life-cycle assessmentsExecutive summaries from a variety of scientific white papers can offer us life cycle insights into different energy sources. Here are a few to peruse.

Active Transportation: Life-cycle analysis provides a comprehensive view of the environmental impact of transportation infrastructure due to processes involving construction, operation, and maintenance.

  • Airplanes show the highest GHG emissions — 3 times that of cars and 6 times that of buses.
  • Cars or buses show higher GHG emissions when considering life-cycle impacts than the results without the life-cycle impacts because the GHG impact of manufacturing and operating automobiles and buses could be greater than that of other modes.
  • Walking does not require any tools, so its life-cycle impact is minimal compared to other modes.
  • The GHG impact of producing and maintaining bicycles is much smaller than that of automobiles or public transportation vehicles.
  • On balance, active transportation modes produce far less emissions than other modes even after taking into account all the life-cycle impacts.

Biomass: Co-firing biomass as a means of GHG abatement becomes economically competitive with traditional carbon capture and sequestration only after an incentive is in place to mitigate emissions.

  • The point at which co-firing becomes an attractive option depends on the potential value of CO2, the level of an emissions penalty, and the type of plant.
  • The break-even value would either represent the amount required on the sale of the captured CO2 in the capture cases, or a benefit received for the use of biomass as a fuel source in the non-capture cases, when compared to the economics of a supercritical (SC) PC plant without capture or co-firing.
  • This value would need to be reached before incentivizing either CO2 capture or biomass co-firing. The emissions penalty would be the minimum value required to encourage the use of capture technology or abatement using biomass.

Hydropower: The assessment considers various ecological influence groups which could be generally categorized as — global warming, ozone formation, acidification, eutrophication, ecotoxicity, human toxicity, water consumption, stratospheric ozone depletion, ionizing radiation, and land use.

  • Though water itself is not lethal, the electricity production process involves many stages, which creates environmental issues.
  • Furthermore, the transportation medium of these elements to the plant location releases hazardous particles i.e., carbon monoxide, dust, and carcinogenic particles.
  • Among the key impact groups, the whole outcomes show that a substantial ecological influence occurred at non-alpine region plants over alpine region plants. The reason behind this is that the long distance transportation of raw materials in non-alpine region hydropower plants due to unavailability at nearby locations where raw materials of the alpine based plants is available at nearby locations.
  • The maximum impact is occurred at fine particulate matter formation impact category due to freshwater eutrophication category by both types of hydropower plants. The reason behind these impacts is the amount of toxic materials present as constituent of plant structure and its electricity production steps.

Natural Gas: This analysis takes into account a wide range of performance variability across different assumptions of climate impact timing.

  • Natural gas-fired baseload power production has life cycle greenhouse gas (GHG) emissions 35% to 66 % lower than those for coal-fired baseload electricity.
  • The lower emissions for natural gas are primarily due to the differences in average power plant efficiencies (46% efficiency for the natural gas power fleet versus 33% for the coal power fleet) and a higher carbon content per unit of energy for coal in comparison to natural gas.
  • Natural gas-fired electricity has 57% lower GHG emissions than coal per delivered megawatt-hour (MWh) using current technology when compared with a 100-year global warming potential (GWP) using unconventional natural gas from tight gas, shale, and coal beds.

Petroleum: Petroleum is produced from crude oil, a complex mixture of hydrocarbons, various organic compounds, and associated impurities.

  • The crude product exists as deposits in the earth’s crust, and the composition varies by geographic location and deposit formation contributors. Its physical consistency varies from a free flowing liquid to nearly solid. Crude oil is extracted from geological deposits by a number of different techniques.
  • When comparing transportation GHG emissions, both the tailpipe or tank-to-wheel (TTW) emissions, and the upstream or well-to-tank (WTT) emissions are considered in the full well to wheel (WTW) life cycle.
  • Extracting, transporting, and refining crude oil and bio-based alternatives on average account for approximately 20-30% of well-to-wheels (WTW) greenhouse gas (GHG) emissions with the majority of emissions generated during end use combustion in the vehicle phase (TTW).
  • GHG emissions in the generic cases range from ≈105 to 120 g of CO2/MJ [gasoline basis, full fuel cycle, lower heating value (LHV) basis] when co-produced electricity displaces natural-gas-fired combined-cycle electricity.
  • The carbon intensity varies with the energy demand of TEOR, the fuel combusted for steam generation, the amount of electric power co-generated, and the electricity mix. The emission range for co-generation-based TEOR systems is larger (≈70−120 g of CO2/MJ) when coal is displaced from the electricity grid (low) or coal is used for steam generation (high). The emission range for the California-specific cases is similar to that for the generic cases.

Solar: Life-cycle assessment is now a standardized tool to evaluate the environmental impact of photovoltaic technologies from the cradle to the grave.

  • The carbon footprint emission from PV systems was found to be in the range of 14–73 g CO2-eq/kWh, which is 10 to 53 orders of magnitude lower than emission reported from the burning of oil (742 g CO2-eq/kWh from oil).
  • Negative environmental impacts of PV systems could be substantially mitigated using optimized design, development of novel materials, minimize the use of hazardous materials, recycling whenever possible, and careful site selection. Such mitigation actions will reduce the emissions of GHG to the environment, decrease the accumulation of solid wastes, and preserve valuable water resources.
  • Following a report published by the International Renewable Energy Agency (IRENA), the volume of PV panel waste could globally yield a value of up to 60–78 million tons by 2050. Recycling solar cell materials can also contribute up to a 42% reduction in GHG emissions.

Wind: Wind power presents minimal emissions and environmental impacts during the working phase, being considered as a “cleaner” generation source. But not all stages of wind power are so efficient.

  • The extraction of raw materials, manufacturing, and transportation as part of wind power construction have significant emissions of CO2 and environmental impacts.
  • Not only will improvements in logistics, transportation, a mixed electricity supplement, and a more efficient equipment production reduce CO2 emissions from wind power construction, new basic materials and innovative built techniques may decrease CO2 emissions and energy demand.
  • Decommissioning stage may present a reduction of the energy consumption and CO2 emissions through reusing equipment, recycling critical materials in the end of life cycle, reducing the extraction of raw materials and the total consumption of resources.
  • Such changes may create unexpected fluctuations in the market, such as shortages of supplies and dependence on exporters.

Of course, there are many other types of energy sources and other data analyses to consult to consider life cycle assessments. For more ideas, try Life Cycle Analysis of Energy for a good starting point.

Global energy giant RWE halts US offshore wind because of Trump

Global energy giant RWE halts US offshore wind because of Trump

Global renewable developer and energy giant RWE has halted its US offshore wind operations “for the time being” because of the “political environment” the Trump administration has created.

RWE, Germany’s biggest electricity producer, said in March that it had dialed back its US offshore wind activities. But now, CEO Marcus Krebber said in a speech transcript, which he’ll deliver at the company’s Annual General Meeting in Essen on April 30, that its US offshore wind business is now closed (but it wasn’t all bad news): 

In the US, where we have stopped our offshore activities for the time being, our business in onshore wind, solar energy, and battery storage has so far been developing very dynamically. At the start of this year, we reached an important milestone when our US generation capacity hit the 10 gigawatt mark. The construction of a further 4 gigawatts is secured.

He went on to say that renewables have created regional value and jobs, but that the company remains “cautious given the political developments.” RWE has introduced more stringent requirements for future US investments:

All necessary federal permits must be in place. Tax credits must be safe harbored and all relevant tariff risks mitigated. In addition, onshore wind and solar projects must have secured offtake at the time of the investment decision. Only if these conditions are met will further investments be possible, given the political environment.

About half of RWE’s installed renewable capacity is in the US, where it’s the third-largest renewable energy company through its subsidiary, RWE Clean Energy. RWE holds the rights to develop US offshore wind projects in New York, Louisiana, and California.

RWE paid $1.1 billion for the New York lease area in 2022, where it’s meant to develop the 3 gigawatt (GW) Community Offshore Wind with the UK’s National Grid. Community Offshore Wind was projected to come online in the early 2030s and expected to power more than a million homes.

The developer paid $5.6 billion for the Louisiana lease in the Gulf of Mexico in 2023 as the lone bidder for development rights, and the Canopy Offshore Wind project off Northern California was not expected to be completed for another decade.

Trump’s memecoin dinner contest earns insiders $900,000 in two days

Trump's memecoin dinner contest earns insiders 0,000 in two days

WASHINGTON – President Donald Trump and his allies have raked in nearly $900,000 in trading fees over the past two days from the president’s $TRUMP cryptocurrency token, according to Chainalysis, a blockchain data company. 

The surge came after a Wednesday announcement in which the top 220 holders of the token were promised dinner with the president.

“Have Dinner in Washington, D.C. With President Trump,” reads a message on the front page of the Trump coin’s website. The event, which is black tie optional and hosted at the president’s private club in the Washington area, is scheduled for May 22, with a reception for the top 25 holders. A “VIP White House Tour” will take place the following day, the site says. The website also hosts an active leaderboard displaying the usernames of top buyers.

The $TRUMP memecoin jumped more than 50% on the dinner news, boosting its total market value to $2.7 billion. It was met with fierce criticism from some of Trump’s political opponents who said the move was further evidence that the president was using crypto to enrich himself. Sen. Chris Murphy, D-Conn., a prominent Trump critic, wrote on X that the sale was “the most brazenly corrupt thing a President has ever done. Not close.”

Roughly 80% of the $TRUMP token supply is controlled by the Trump Organization and affiliates, according to the project’s website. Since its launch in January, trading activity has generated about $324.5 million in trading fees for insiders, Chainalysis found. These fees are generated through the token’s built-in mechanism that routes a percentage of each trade to wallets controlled by the project — wallets that, according to the website, are linked to the coin’s creators.

Memecoins, often referred to as meme tokens, are a subset of digital assets that use blockchain technology and derive their value largely from internet culture, memes and social media hype rather than from an underlying utility or asset. The originators of memecoins can make fees when their coins are bought and sold.

They have grown in popularity in recent years as speculative assets, with some coins including dogecoin and fartcoin amassing total market values in excess of $1 billion.

Most of the $TRUMP supply remains locked under a three-year vesting plan, with coins gradually becoming available over time. Lockups like these are meant to protect investors by preventing insiders from cashing out all at once — a scheme commonly known in the crypto world as a “rug pull.” Vesting schedules aim to give retail buyers confidence that early holders won’t overwhelm the market and tank the token’s value.

Still, the dinner contest is being viewed by critics as an unusually explicit attempt to monetize presidential access. 

As CNBC reported Friday, Democratic Sens. Adam Schiff of California and Elizabeth Warren of Massachusetts are urging the U.S. Office of Government Ethics to investigate whether the promotion constitutes “pay to play” corruption.

The White House did not respond to a request for comment. The company behind the memecoin also did not respond to a request for comment.

Delaney Marsco, the director of ethics at the Campaign Legal Center, a nonprofit focused on campaign finance and government accountability, told NBC News the coin and dinner contest amounted to an unprecedented ethics breach — though it is unlikely to be illegal.

“Criminal conflicts of interest statutes don’t apply to the President,” she said. “That has allowed him to go against decades of of norms that every modern president since Carter has adhered to, which is to divest your financial interests, rid yourself of your businesses, and kind of go in to the presidency with a clean financial slate so that no one could accuse you of manipulating policy decisions or using your position in order to enrich yourself.” 

“The fact that he is not barred by the law from having these financial interests like this meme coin allows him to engage in a lot of seemingly corrupt activity. It has the appearance of a pay to play, so the President is apparently selling access to himself,” Marsco added.

Molly White, an independent crypto researcher, told NBC News that the leaderboard only shows top $TRUMP holders — and then only by their chosen screen name, making it difficult to identify who is paying to potentially join the dinner.

Schiff and Warren have cited public reports showing that some $TRUMP investors have ties to foreign exchanges or received funds from crypto platforms banned in the U.S., including Binance.

White also noted that at least one top $TRUMP owner has an account on Binance, a cryptocurrency company that doesn’t allow American users.

Trump was elected with significant help from the cryptocurrency industry, which poured tens of millions of dollars into the 2024 election, outpacing corporate donations from traditional sectors like banking and oil. After opposing digital assets during his first term, Trump pivoted in 2024 to campaign as a champion of cryptocurrency, casting Democrats as hostile to innovation and as advocating for tighter regulation. 

The $TRUMP token itself offers no product or service, according to the project’s website. It is part of a broader push by the Trump family into digital assets, despite the market’s volatility and regulatory risks.

In addition to the $TRUMP and $MELANIA meme coins, the family is backing World Liberty Financial, a decentralized finance venture that has raised $550 million across two token sales since last October. Buyers are barred from reselling their tokens and receive no share of profits — but a Trump-affiliated entity is entitled to 75% of net revenue, including token sale proceeds.

Together, these projects have created new streams of revenue for Trump and his inner circle at a time when regulatory oversight of cryptocurrency has weakened sharply under his administration.

Drive Electric Earth Month, continues this weekend, get your EV Qs answered

It’s that time of year again, time for events across the country to show off electric vehicles at Drive Electric Earth Month.

Drive Electric Earth Month is an offshoot of Drive Electric Week, a long-running annual tradition hosting meetups mostly in the US, but also occasionally in other countries. It started as Drive Electric Earth Day, but since not every event can happen on the same day, they went ahead and extended it to encompass “Earth Month” events that happen across the month of April. It’s all organized by Plug In America, the Sierra Club, the Electric Vehicle Association, EV Hybrid Noire, and Drive Electric USA.

Events consist of general Earth Day-style community celebrations, EV Ride & Drives where you can test drive several EVs in one place, and opportunities to talk to EV owners and ask them questions about what it’s like to live with an EV, away from the pressure of a dealership.

This month, there are 158 events registered across the US and 1 in Mexico (including one online webinar about things to consider when purchasing an EV).

Events have been happening all month, but the biggest weekend is this upcoming one, APril 26-27.

One really neat event was the Asheville event, which showcased the resiliency of EVs in an area devastated by Hurricane Helene, which was made more severe by climate change. That event was attended by the Rivian R1T which famously got dragged 100 feet submerged in mud and came out running fine.

But the bulk of the events happened on the weekends surrounding Earth Day, April 22, so there were several last weekend and will be even more this upcoming weekend.

There are plenty of events in the big cities where you’d expect, but Plug In America wanted to highlight a few of the events in smaller places around the country. Here’s a sampling of upcoming events:

  • Big Island EV – Cruise and Picnic in Waimea, HI on April 26, 10am-1pm – EV drivers will congregate in various places around the Big Island (Kona, Waimea, Waikoloa and Hilo), then drive up Saddle Road to the Gil Kahele Recreation Area on Mauna Kea for a potluck and a chance to talk about the experience of owning EVs on the Big Island.
  • Santa Barbara Earth Day 2025 and Green Car Show in Santa Barbara, CA on April 26-27, 11am-8pm – This is part of Santa Barbara’s Earth Day celebration, which routinely attracts 30,000 participants and is one of the longest-running Earth Day celebrations on the planet. The Green Car Show includes ride & drives and an “Owners Corner” where owners can showcase their EVs and attendees can check them out and ask questions.
  • Earth Day’25 – EV’s role in a sustainable future in Queretaro City, Mexico on April 26, 9am-4pm – The sole Mexican event, this is a combined in-person/online seminar at the Querétaro Institute of Technology.
  • Norman Earth Day Festival in Norman, OK on April 27, 12-5pm – Another municipal Earth Day festival, with hands-on activities for kids to learn about the environment. A portion of the parking lot reserved for an EV car show for EV owners who pre-register to show off their vehicles.
  • Oregon Electric Vehicle Association Test Drive & Information Expo in Portland, OR on April 27, 10am-4pm – This one is at Daimler Truck’s North American HQ, and will have several EVs for test drives, owner displays (including DIY gas-to-EV conversions), and keynote presentations by EV experts. They’ll even have a 1914 Detroit Electric EV available for test rides!
  • And, we at Electrek want to give a shoutout to Rove’s EV Drive Days in Santa Ana 10am-3pm April 28 – ROVE is the company behind the “full-service” EV charging concept that we’ve talked about several times here on Electrek, and we like what they’re doing for EV charging. They’ve hosted a few community events, and this is their contribution to Earth Month.

Each event has a different assortment of activities (e.g. test drives won’t be available at every event, generally just the larger ones attended by local dealerships), so be sure to check the events page to see what the plan is for your local event.

These events have offered a great way to connect with owners and see the newest electric vehicle tech, and even get a chance to do test rides and drives in person. Attendees got to hear unfiltered information from actual owners about the benefits and trials of owning EVs, allowing for longer and more genuine (and often more knowledgeable) conversations than one might normally encounter at a dealership.

And if you’re an owner – you can show off your car and answer those questions for interested onlookers.

To view all the events and see what’s happening in your area, you can check out the list of events or the events map. You can also sign up to volunteer at your local events, and if you plan to show off your electric car, you can RSVP on each event page and list the vehicle that you plan to show (or see what other vehicles have already registered).
