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.”

Sustainable sculpture to power Houston multicultural arts building

arts meets energy transition

The City of Houston has unveiled the first look at the latest permanent public artwork that will be installed in the Second Ward in 2024. The sculpture is the first-ever environmentally sustainable art piece that will generate electricity for the nearby City-owned Latino multicultural performing arts theater.

Arco del Tiempo (Arch of Time) is a 100-foot tall arch designed by Berlin-based artist and architect Riccardo Mariano. Several years have been put into the making of this project, dating as far back as 2019. Mariano had entered the idea into a Land Art Generator Initiative (LAGI) design competition in the Houston sister-city of Abu Dhabi. From there, it was chosen to be developed full-scale and installed at Guadalupe Plaza Park.

According to a press release, the sculpture can measure time and cast beams of sunlight onto the ground, creating a connection between "the celestial and the terrestrial" through the geometry of the design.

The light beams are different based on the four seasons and the time of day, constantly shifting and responding to the latitude and longitude of the city from space. Mariano said that his sculpture is a "practical example" of how physical art can interact with the abstract, such as the Earth's movement around the sun.

"The apparent movement of the sun in the sky activates the space with light and colors and engages viewers who participate in the creation of the work by their presence," said Mariano. "Arco del Tiempo merges renewable energy generation with public space and into the everyday life of the Second Ward. Inspired by science and powered by renewable energy, the artwork is a bridge between art and technology and encourages educational purposes while improving public space. At night the space within the arch will be used as a stage for outdoor public events.”

Arco del Tiempo will do more than just be an aesthetically pleasing sight for the community. Its meaningful, functional purpose will be to generate about 400,000 kilowatt-hours of electricity per year, and power the Talento Bilingüe de Houston. LAGI founding co-director Elizabeth Monoian said in the release the sculpture will generate over 12 million kilowatt-hours of power throughout its lifetime, which equals the removal of 8,500 metric tons of carbon dioxide from the atmosphere.

"Through the clean energy it produces, Arco del Tiempo will pay back its embodied carbon footprint," Monoian said. "In other words, all the energy that went into its making—from the smelting of the steel to the drilling that puts the final cladding into place—will be offset through the energy it generates. Beyond its break-even point, which we will track and celebrate with the community, the artwork will be a net-positive contributor to a healthy climate and the planet will be better off for its existence.”

In a statement, Houston Mayor Sylvester Turner praised the unique art piece as more than just a sculpture, but as a "monument to a new era of energy."

"The City of Houston has always stood at the vanguard of energy innovation and the Arco del Tiempo artwork stands in that tradition, highlighting Houston’s role as an art city and as global leader in the energy transition," Mayor Turner said. "We are inspired by the vision and creative thinking. Marrying clean energy, the built environment, and truly World Class art is Houston.”

Texas House Democrats urge Trump administration to restore $250M solar grant

solar grants

Eight Democratic members of the U.S. House from Texas, including two from Houston, are calling on the Trump administration to restore a nearly $250 million solar energy grant for Texas that’s being slashed by the U.S. Environmental Protection Agency (EPA).

In a letter to Lee Zeldin, head of the EPA, and Russell Vought, director of the federal Office of Management and Budget (OMB), the House members urged the two officials to reinstate the nearly $250 million grant, which was awarded to Texas under the $7 billion Biden-era Solar for All program. The Texas grant was designed to assist 28,000 low-income households in installing solar panels, aiming to reduce their energy bills.

“This administration has improperly withheld billions in congressionally appropriated funding that was intended to benefit everyday Americans,” the letter stated.

The letter claimed that numerous court rulings have determined the EPA cannot repeal already allocated funding.

“Congress made a commitment to families, small businesses, and communities across this country to lower their utility bills and reduce harmful pollution through investments in clean energy. The Solar for All program was part of that commitment, and the EPA’s actions to rescind this funding effectively undermine that congressional intent,” the House members wrote.

The six House members who signed the letter are:

  • U.S. Rep. Sylvia Garcia of Houston
  • U.S. Rep. Al Green of Houston
  • U.S. Rep. Greg Casar of Austin
  • U.S. Rep. Jasmine Crockett of Dallas
  • U.S. Rep. Lloyd Doggett of Austin
  • U.S. Rep. Julie Johnson of Dallas
  • U.S. Rep. Marc Veasey of Fort Worth

The nearly $250 million grant was awarded last year to the Harris County-led Texas Solar for All Coalition.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.
