As the world population makes a jump towards more than 9 billion people by 2050, the race to net-zero is more important than ever. An increase in population means an increase in the demand for energy. With everything from greenhouse gases, pollution, carbon and nitrogen deposition putting a strain on planet Earth, community and business leaders are making commitments to advance the energy transition.

Companies like ExxonMobil, NRG, and Shell play an important role in helping the world transition to renewable energy sources. Here are three ways that these energy companies are working towards an energy abundant, low-carbon future.

NRG Energy

Headquarted in Houston, NRG Energy is the leading integrated power company in the U.S. In 2022, NRG introduced a new Sustainability and Resiliency Impact Study as part of Harris County’s Climate Action Plan to reduce the city’s carbon emissions by 40% by 2030. The initiative includes $34 million in park upgrades and is expected to save $54 million.

That same year, Evolve Houston, a nonprofit working to accelerate electric vehicle adoption within the Greater Houston area, launched an e-mobility microgrant initiative funded by Evolve Corporate Catalysts, General Motors and bp. With five founding members, among them being NRG Energy and Shell, the goal of the initiative is to improve regional air quality and reduce greenhouse gas emissions in the Greater Houston area.

At the top of 2023, Reliant Energy and NRG launched the Simple Solar Sell Back electricity plan for Texans aimed at providing solar panels to local homes for lower electricity bills.

Shell

On a mission to improve their own operations, Shell is addressing energy efficiency over time and capturing or offsetting unavoidable greenhouse gas emissions. Headquartered in London. Shell is on a mission to become a net-zero emissions energy business by 2050. In 2022, the British multinational company invested $6 million to create the Prairie View A&M Shell Nature-Based Solutions Research Program, funded through the company’s Projects & Technology organization dedicated to funding research to develop new technology solutions.

In March of 2022, Shell gifted the University of Houston $10 million to bolster the institution’s efforts to establish the Energy Transition Institute which focuses on the production and use of reliable, affordable and cleaner energy for all. The company also launched the residential power brand Shell Energy offering 100% renewable electricity plans.

ExxonMobil

ExxonMobil is one of the world’s largest publicly traded international oil and gas companies. In 2021, the multinational oil and gas corporation pledged to invest more than $15 million in solutions to lower greenhouse gas emissions initiatives across six years. As a part of their approach to improve air quality, ExxonMobil is working to:

  • Understand the composition and extent of our emissions
  • Meet or exceed environmental regulations
  • Reduce air emissions to minimize potential impacts on local communities
  • Monitor the science and health standards related to air quality

Throughout the years, plastics have become an essential component of products, packaging, construction, transportation, electronics and more. While plastics are durable, lightweight and cheap, they also emit 3.4% of global greenhouse gas emissions. Late last year, the major corporation announced the successful startup of one of the largest advanced recycling facilities in North America. Located in Baytown, Texas, the recycling facility uses proprietary technology to break down raw materials for new products and is expected to have nearly 1 billion pounds of annual advanced recycling capacity by the end of 2026.

According to their 2023 Advancing Climate Action Progress Report released early this year, the corporation plans to reduce greenhouse gas emissions through 2030.

From resolving power grid issues to developing renewable energy technologies, Houston energy companies are powering today to empower the future.

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”
