The Colorado Plateau has abundant oil, gas, and alternative energy potential. Carrell et al. Elements of biodiversity (e.g.,
Methane is the second most abundant greenhouse gas after carbon dioxide, albeit a distant second. The gas also escapes during fossil fuel extraction and distribution and is emitted during fires. White of the Institute of Arctic and Alpine Research, University of Colorado, Boulder, Colo.; Earlier post.) Bruhwiler, P.C.
In their commentary, Andreas Goldthau (Royal Holloway University of London), Kirsten Westphal (German Institute for International and Security Affairs (SWP)), Morgan Bazilian (Colorado School of Mines) & Michael Bradshaw (University of Warwick) present four geopolitical scenarios to illustrate how varied the transition could be by 2030.
California consistently imports about 30% of its electricity and natural gas is the dominant fuel for the electricity that it generates internally. million tonnes), while Colorado experienced the greatest absolute increase (11.8 ClimateChange Emissions' The greatest absolute decline was 58.8 million tonnes (18.3%).
US and Swiss researchers have modeled two climate scenarios with very high carbon emissions—above the A1F1 scenario, currently representing the upper bound of predicted carbon emissions in the IPCC work—to investigate the resulting climatechange implications. —Sanderson et al. —Sanderson et al.
For almost four years, her airport has been powered by a mix of on-site natural gas generators and solar panels. Airports and other infrastructure, such as the electric grid itself, are also increasingly under threat by natural disasters, many of which are linked to climatechange. airports from 2015 to 2022.
And it was the seemingly impossible goal of cutting Berkeley’s greenhouse gas emissions by a full 80% by 2050 – as required by a referendum vote of the Berkeley citizens. Another great model is being set outside of California’s borders by Boulder County, Colorado. No matter the motivation, these people get it.
Ceres is a national network of investors, environmental organizations and other public interest groups working with companies and investors to address sustainability challenges such as global climatechange. Oil shale production requires 1.5
Under this cost-shared research and development (R&D), DOE is awarding $51 million to nine new projects for coal and natural gas power and industrial sources. This work will focus on designing a carbon capture system capable of capturing 50 to 70 percent of CO 2 emissions from blast furnace gas. LH CO 2 MENT Colorado Project.
Scientists from the Karlsruhe Institute of Technology (Germany), University of Colorado Boulder, and Universidad Nacional Autónoma de México performed a “CT Scan” of the atmosphere, moving along latitudes and longitudes, measuring particle concentrations and compositions in the upper troposphere.
Great news for drivers looking to purchase an electric vehicle in Colorado! On May 11, 2023, Colorado Governor Jared Polis signed House Bill 23-1272 into law. With the upcoming changes being put in place by the new law, Colorado will have the highest state EV tax credit in the country. 4 , and more.
The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth’s stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. Darin Toohey.
The Creative Greenius says you can now expect a bold United States policy on cutting greenhouse gas emissions, a rapid shift away from carbon-based fuels to renewables and a science-based approach to water policy and other critical resources. Change is but mere weeks away. And again, if that bugs you - so much the better.

states and two Canadian provinces, where furnaces and boilers burning fossil gas, fuel oil or propane are more commonly used. But the DOE will help them expand into cold climate markets by engaging with stakeholders in those regions, a DOE spokesperson told IEEE S pectrum.
In what the city is calling a national first, Louisville, Colorado officials held a “ribbon cutting” last Tuesday to celebrate the launch of a new, all-electric residential recycling and waste collection fleet, which is already the city’s streets. Electrek’s Take First off, who even knew they had a Louisville in Colorado!?
Imagine a transportation option that has the fun and flexibility of a bike, is a fraction of the price of a car, can park almost anywhere for free, and produces almost zero climate-changing emissions. What’s more is that electric motorcycles, like other EVs, require far less maintenance than their gas counterparts. Think again.
With climatechange awareness increasing, gas prices continuing to climb, EV charging stations expanding, and tons of new EV options hitting the market each year, it’s no surprise that electric vehicle purchases are skyrocketing. Electric vehicles are becoming more and more common on the roads across the country.

Understandably, Horse Heaven’s developer, Colorado-based Scout Clean Energy, isn’t happy. But natural gas is the second-largest in-state source of net generation, fueling about 18% of Washington’s total electricity generation in 2023, according to the US Energy Information Administration ( EIA ).
Today, the art of turning heat from burning gas, nuclear fission, Earth’s core, the sun, and other sources into useful energy underpins modern life. The first arises from atoms vibrating against one another as typically occurs in a solid; the second arises from bulk movements of particles, such as gas molecules in air.
