Safe, low carbon, inexpensive: the renewable alternatives to fracking
In its haste to get fracking, the UK Government is neglecting safe, clean alternatives that could be providing low-carbon gas and heat energy, writes Keith Barnham. If these renewable resources were to enjoy the same level of government support as fracking they would provide more new jobs and reduce energy costs lower than fracking could
Sustainable Plastics Inspired by Nature
But the ubiquitous petroleum product doesn''t have to be a permanent fixture in our society. Technical advances are now making bioplastics—polymer materials derived from plant sources (biomass)—a functional yet renewable alternative to petroleum-based plastics (Fig. 1). This development could have a potentially transformative effect on the

The advantages and disadvantages of renewable energy
Renewable energy has multiple advantages over fossil fuels. Here are some of the top benefits of using an alternative energy source: Renewable energy won''t run out. Renewable energy has lower maintenance requirements. Renewables save money. Renewable energy has numerous environmental benefits. Renewables lower reliance on foreign energy sources.
Benefits of Renewable Energy Use
In contrast, most renewable energy sources produce little to no global warming emissions. Even when including "life cycle" emissions of clean energy (ie, the emissions from each stage of a technology''s life—manufacturing, installation, operation, decommissioning), the global warming emissions associated with renewable energy are minimal [].
U.S. transition to clean energy is happening faster than you think
Huge swaths of the country are pivoting from fossil fuels, toward wind, solar and other renewables. New York Times climate reporter Brad Plumer discusses this progress and roadblocks that lie ahead.

6 FAQs about [Renewable alternatives]
Why are renewables becoming a more important energy source?
Now that we have innovative and less-expensive ways to capture and retain wind and solar energy, renewables are becoming a more important power source, accounting for more than 12 percent of U.S. energy generation.
Is there an alternative to shutting off the energy system?
"If it's especially windy outside and you've got surplus electricity being generated, there's an alternative to shutting the system off," says Scott Hamilton, renewables division manager at Xodus, an energy consultancy. "Rather than waste those extra electrons, they can be used to create hydrogen fuel."
Why do renewables have a higher share in the energy mix?
This includes not only electricity but also transport and heating. Electricity forms only one component of energy consumption. Since transport and heating tend to be harder to decarbonize – they are more reliant on oil and gas – renewables tend to have a higher share in the electricity mix versus the total energy mix.
Are renewables a good investment?
Investment in renewables, especially solar, tends to be more effective in creating jobs than coal, gas or oil. [ 146 ][ 147 ] Worldwide, renewables employ about 12 million people as of 2020, with solar PV being the technology employing the most at almost 4 million. [ 148 ]
What percentage of heating & cooling energy is renewable?
About 10% of heating and cooling energy is from renewables. [ 164 ] The International Renewable Energy Agency (IRENA) stated that ~86% (187 GW) of renewable capacity added in 2022 had lower costs than electricity generated from fossil fuels. [ 165 ]
Are renewables more cost-effective?
Policies such as feed-in tariffs in China and Vietnam have significantly increased renewable adoption. Furthermore, from 2013 to 2022, installation costs for solar photovoltaic (PV), onshore wind, and offshore wind fell by 69%, 33%, and 45%, respectively, making renewables more cost-effective.
