Local and state leaders shared updated plans this month on a first-of-its-kind structure that uses art to generate solar energy.

Slated to be located at Mason Park in Houston’s East End, the new "Arch of Time" is a freestanding sundial art installation that will generate 400,000 kilowatt-hours of power per year using 60,000 solar photovoltaic cells on its south-facing exterior.

The project will be part of a larger pavilion at the park and is being led by the renewable energy organization Land Art Generator Initiative (LAGI). Architect Riccardo Mariano will design the space. It will be funded by donations and cost $20 million, organizers say.

The project, originally known as "Arco del Tiempo," was announced in 2023. At the time, the city shared the installation would be installed at Guadalupe Plaza Park in 2024.

The project's latest update was announced during Houston City Hall’s Earth Day 2025, where organizers described it as "a monument to Houston's past, present, and future leadership as the energy capital of the world."

The 100-foot structure will also serve as a 25,000-square-foot shaded area, or microclimate, during hot days. It will also feature a stage performance space and a power hub for emergencies. Due to the artwork's north opening and south narrowing, it is also expected to help channel the breezes, according to LAGI.

The organization says it is also expected to generate enough power to fuel all of Mason Park.

“Mason Park will soon, perhaps become the first major park in the country that is powered entirely by the sun,” Houston City Council Member Joaquin Martinez said at the news conference. “The economic benefits are clear.”

Former Houston Park and Recreation director Joe Turner selected the East End park as the location of the arch and believes it could be used as a STEM tool for students.

“All the STEM education that can come from the way we use the solar collectors, the way it has a water collection system that's going to collect the runoff water, there's so much we can do to teach kids STEM,” said in a Houston Park and Recreation Department video.

The project is about two years away from being completed. LAGI says the Arch of Time will be the “first public art project of its scale to stand as a net-positive contribution to a sustainable climate.”

A Japanese air conditioner manufacturer has teamed up with the city of Houston on an energy efficiency initiative.

Daikin Comfort Technologies, which has its 4.2 million-square-foot Daikin Texas Technology Park in Waller, Texas, has partnered with the city of Houston to provide advanced air conditioning and heating solutions to help homeowners with energy efficiency and general comfort.

The company will install up to 30 horizontal discharge inverter FIT heat pump units over the next three years. The units will be provided to low-to-moderate-income households, which will include seniors over the age of 62, and homes renovated through the Housing and Community Development Department’s Home Repair Program. The new units will offer internet connectivity for remote monitoring and control. The installations align with Houston's Home Repair Program reconstruction plans.

“We are proud to partner with the City of Houston to launch this program that can directly advance their vision for decarbonization and increasing grid resiliency through higher efficiency,” CEO Satoru Akama says in a news release. “Through this program, Homeowners will have a premium system that will not only provide comfort but save on their monthly bills and do so in a way that lowers site emissions of CO2 compared to traditional, non-inverter systems. At Daikin, we are focused on changing the culture of air conditioning in North America and are looking forward to having a direct impact in our hometown.”

The initiative coincides with the company’s 100th year anniversary and National Air Condition Appreciation Days, which was coined by Mayor John Whitmire on August 13. Air Conditioning Appreciation Days ran from July 3 until August 15.

“The city thanks Daikin for this collaboration. Houstonians, especially seniors, (that) must have the resources to stay comfortable during extreme temperatures,” Whitmire adds. “This partnership reflects our dedication to caring for the well-being of our community.”

Awareness is part of the appreciation days, as Daikin recommends homeowners and facilities to clean filters, schedule maintenance checkups and look at ways to lower energy use.

“Through these new energy-efficient solutions, Daikin is helping the city promote a more sustainable environment for our community, and we are thankful for their example of how public-private partnerships can make a positive difference in society,” Houston Council Member Sallie Alcorn says in a news release.

do your part

The City of Houston Solid Waste Management Department is launching a free Food Waste Drop-Off pilot program through the end of February.

The program is in collaboration with Council Member Sallie Alcorn, Zero Waste Houston and the City of Houston Health Department, and allows residents to drop off food scraps at four different locations. The locations are:

  • Kashmere Multi-Service Center, Mondays from 2 to 5 pm
  • Acres Homes Multi-Service Center, Tuesdays from 2 to 5 pm
  • Alief Neighborhood Center, Wednesdays from 4 to 7 pm
  • Sunnyside Multi-Service Center, Thursdays from 3 to 6 pm

Houston residents, businesses, and institutions generate 6.2 million tons of municipal solid waste per year according to the Solid Waste Department program.

“You’ll find when you start composting your food scraps, there is a lot less trash generated in your home, at your curb, and taken to the landfill,” Alcorn says in a news release.

The Solid Waste Management Department provides solid waste services with the collection, disposal, and recycling of discarded material in an environmentally-friendly and cost effective way.

“The Solid Waste Department is eager to continue to provide innovative programs that divert waste from the landfill and actively engage Houston residents,” says Mark Wilfalk, Director of Solid Waste Management in the release.

Electric vehicles to take center stage at annual Houston event

vroom, vroom

Houston Auto Show, which is a long running event for auto enthusiasts, will feature its largest electronic vehicle representation to date this year.

The event will feature an EV Pavillion and Evolve Houston’s electronic showroom at the January 24 to 28 event at NRG Center. Attendees will have the opportunity to learn about what it means to go the EV route from environmental impact, performance, cost effectiveness, and other factors.

This year, vehicles like Nissan's Ariya Platinum+ AWD, Chevrolet’s Bolt EV, Ford’s F-150 Lightning and others will be on display at the EV Pavillion. CenterPoint Energy, Reliant, and the University of Houston were part of Evolve's 2023 showroom.

A recent study from SmartAsset ranked states with the most electric vehicle chargers by looking at the closest equivalent to a trip to the gas station, in terms of “refueling” – per capita. Texas is behind other similarly-sized states.

“Houston maintains some of the lowest population density and longest commute distances of major U.S. cities, and we have an immense amount of business and goods that flow through Houston,” Casey Brown, executive director and president of EVOLVE, previously told EnergyCapital. “We see a landscape that can uniquely achieve larger financial and environmental benefits of EV technologies. One way that we share these benefits is being the Presenting Sponsor of the Houston Auto Show.”

Houston Automobile Dealers Association Executive Vice President and event organizer RoShelle Salinas has noted there has been an uptick in EV demand for these events since the first one debuted at the 2020 show.

Evolve Houston, which was founded in 2018 through Houston’s Climate Action Plan, is one of the organizations leading the way in the EV space, as the company still aims for its goal to have half of the vehicles in the city be electric by 2030. Evolve assists and funds those looking to make the transition to electric with the Grant Tracker, which aims to make it easier to find funding opportunities, and assist with current grants available to organizations and individuals that are committed to a goal of zero emissions. The tracker serves as a tool to assist with purchasing an EV and charging equipment.

The Biden administration recently announced it is awarding $623 million in grants to help build an electric vehicle charging network across the nation. Grants will fund 47 EV charging stations and related projects in 22 states and Puerto Rico, including 7,500 EV charging ports according to officials. Texas is expected to see a chunk of that funding. Last year, the city of Houston approved $281,000 funding for the expansion of free electric vehicle rideshare services in communities that are considered underserved by utilizing services like RYDE and Evolve Houston.

“Evolve Houston has been a sponsor for 2 years and their display has been a great addition to the show because it is not only educational, but there is also a chance for people to test drive vehicles,” Salinas says.

Texas ranks low on most energy-efficient states report

by the numbers

Texas has room to improve when it comes to energy efficiency, recent data from WalletHub shows.

The personal finance website ranked Texas at No. 35 on the latest Most & Least Energy-Efficient States list. Texas improved by one spot on the 2025 report, after coming in at No. 36 last year.

The report measured and ranked the efficiency of auto energy and home energy consumption in the 48 U.S. mainland states based on data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration and the U.S. Department of Transportation – Federal Highway Administration.

Texas earned an overall score of 50.60. It was ranked No. 27 for home energy efficiency and No. 41 for auto efficiency. By comparison, No. 1-ranked Vermont earned a score of 85.30, ranking No. 2 for home energy and No. 6 for out energy.

The top five overall states included:

  • No. 1 Vermont
  • No. 2 California
  • No. 3 Washington
  • No. 4 New York
  • No. 5 Massachusetts

South Dakota earned the top rank for home energy efficiency, and Massachusetts earned the top rank for energy efficiency.

“Energy efficiency doesn’t just help save the planet – it also helps save you money by lowering the amount of electricity, gas, oil or other types of energy you need to consume. While there are some steps you can take to become more energy-efficient on your own, living in the right area can give you a big boost," WalletHub analyst Chip Lupo said in the report. "For example, certain states have much better public transportation systems that minimize your need to drive, at least in big cities. Some places also have better-constructed buildings that retain heat better during the winter or stay cooler during the summer.”

According to the report, some progress is being made in increasing energy efficiency across the country. The U.S. Energy Information Administration expects 26 percent of electricity generation in 2026 will come from renewables. A number of them are being developed in the Houston area, including recent announcements like the Pleasure Island Power Collective in Port Arthur.

Still, Houston earned an abysmal ranking on WalletHub's greenest cities in the U.S. report earlier this year, coming in at No. 99 out of 100. Read more here.

Port Houston reports emissions progress as cargo volumes climb

greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools.

Port Houston aims to be carbon neutral by 2050.

Anning Corporation

Clean energy company Anning Corporation is working to develop geologic hydrogen, a natural carbon-free fuel, using its proprietary stimulation approaches and advanced exploration modeling. The company said that geologic hydrogen has the potential to be the lowest-cost source of reliable baseload electricity in the U.S.

The company was founded by CEO Sophie Broun in 2024 and is a member of Greentown Labs. Last month, it also announced that it was chosen to participate in Breakthrough Energy’s prestigious Fellows Program. Anning raised a pre-seed round this year and is currently raising a $6 million seed round.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTech Nexus LiftOff, and others. Lee is an Activate 2025 fellow.

Eclipse Energy

Previously known as Gold H2, Eclipse Energy converts end-of-life oil fields into low-cost, sustainable hydrogen sources. It completed its first field trial this summer, which demonstrated subsurface bio-stimulated hydrogen production. According to the company, its technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

Eclipse is a spinoff of Houston biotech company Cemvita. It was founded in 2022 by Moji Karimi (CEO and chairman of Cemvita), Prabhdeep Sekhon (CEO of Eclipse), Tara Karimi, and Rayyan Islam. The company closed an $8 million series A this year and has plans to raise another round in 2026.

Loop Bioproducts

Agricultural chemical manufacturing company Loop Bioproducts leverages the physiology of prickly pear cactus grown in Texas to produce bioenergy, food, and remediate industrial wastewater streams. The company uses its remote sensing technology, proprietary image-based machine learning model, and R&D innovation to capture raw biogas from the cactuses and is focused on scaling cactuses as an industrial crop on land.

Rhiannon Parker founded Loop Bioproducts in 2023.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and converts them into pure chemicals and fuels that are free of carbon emissions onsite, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ catalyst program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as chief scientist, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round earlier this year.
