An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
In countries that choose to continue or increase their use of nuclear power, it can reduce reliance on imported fossil fuels, cut carbon dioxide emissions and enable electricity systems to integrate higher shares of solar and wind power. However, a new era for nuclear power is by no means guaranteed.

Contract value: £7.48 million (US$9.7
Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
The SMUD (2020 Sacramento Municipal Utility District) Board of Directors adopted a climate emergency declaration that commits to working toward an ambitious goal of delivering carbon-neutral electricity by 2030.
The flagship project MethanQuest was launched in September 2018, and on it a total of 29 partners from research, industry and the energy sector have come together to work on processes for producing hydrogen and methane from renewables and for using them to achieve climate-neutral mobility and power generation.
The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.
Intelligent Power Generation (IPG) will demonstrate the impact of Flameless Ceramic Turbine technology in UK electric vehicle (EV) charging infrastructure, following a £1-million contract from Highways England. Not only can IPG’s technology deliver low-emission, pollutant-free energy on today’s cleaner fuels.

However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. Wind replacing fossil fuels always reduces air pollution and never has a capture equipment cost. In both plants, natural gas turbines power the equipment. efficient over 6 months, on average.
Recent breakthroughs in separations and catalysis, along with long-trend reductions in solar and windelectricity costs, have significantly increased the potential for cost-competitive renewable fuels from direct air capture (DAC) of CO 2. TW of combined solar and wind capacity for the United States alone will be required.
