A recent report from the International Energy Agency (IEA) suggests that both technologies can be more environmentally friendly than the former.
According to the IEA, the world could see an increase in carbon emissions by 20% over current levels if all the world’s plants were powered by natural gas, and by 40% if all energy came from wind and solar.
The IEA report has generated a lot of buzz, with many experts pointing out the benefits of both technologies.
“With wind and photovoltaic energy, the price of energy is going down dramatically, and with natural gas and hydrogen, the cost of energy will be rising significantly,” said IEA director general, Fatih Birol.
But for many people, the main reason to choose a gas-powered power plant is because it emits fewer pollutants, such as sulphur dioxide and nitrogen oxides.
Some environmentalists, however, are sceptical of the findings, pointing to the findings that show the environmental impact of both types of power plants is similar.
They argue that gas-fired power plants emit fewer pollutants than solar and wind power plants.
Critics also point out that carbon emissions from gas plants are significantly lower than those from nuclear power plants, and that the use of natural gas in electricity generation is also less polluting.
A number of experts, including former Energy Secretary, Lawrence Summers, have also weighed in on the issue.
Many energy experts believe that the current trend of developing renewable energy and switching to more environmentally-friendly forms of energy has a lot to do with the growing popularity of gas and diesel-powered generators.
Despite these positive trends, some experts, such, former energy minister, Peter Garrett, believe the technology is likely to remain the dominant technology in the energy sector.
Mr Garrett told ABC Radio on Wednesday that while he was personally not keen on the IAE report, he was not surprised.
He said it was likely that, in the long run, it would be the gas that dominates.
