A new research report shows that without destroying food production, one-fifth of global energy can be provided by biomass (plants).
The Ukrainian Energy Research Center (UKERC) came to this conclusion after analyzing more than 90 studies worldwide. The center is dedicated to solving key controversial issues in the energy sector and aims to provide authoritative reports with high accuracy and transparency.
A key question that has been debated all the time is what role biomass can play in the future energy system: Some people think that biomass can play a major role in global energy supply, while others worry about Material energy can cause environmental disasters. In order to resolve the key issues of the debate, scientists at the British Energy Research Centre at Imperial College London conducted a systematic review of relevant evidence for the first time.
The report found that the main reason why scientists disagree with these issues is that they make different assumptions about population, eating habits, and land use. One of the focuses of the debate is the increase in the production of food and energy crops.
"If we make the best use of agricultural waste, energy crops, and waste, then the goal of providing one-fifth of the world's energy from biomass is achievable." The report's lead author is Raphael, a researcher at Imperial College London. Slade said. The report also found that from a technical point of view, these goals can even be exceeded, but this requires a proper estimation of changes in food production and eating habits, and these factors are becoming more and more challenging, especially in Asia. And Latin Americans, as their incomes increase, begin to consume more and more meat like Westerners.
"The greater the demand for bioenergy, the more difficult it is to balance the balance between food demand, energy, and environmental protection," Slade said. If fossil fuels are completely replaced by biomass, then it will require all the agricultural and commercial forest lands in the world to support it, and this will be difficult to achieve unless we can produce more food on less arable land.
For increasing bioenergy production, technological progress is probably the least controversial path, but policies also need to encourage innovation and investment. As long as the soil fertility is not destroyed or water resources are consumed in large quantities, increasing the production of food and energy crops will bring a win-win opportunity. The report emphasizes that policy measures are promising in terms of encouraging the development of sustainable biomass, and should not be viewed on the wall.
"The biggest mistake now is to affirm it or reject it. There is actually a great scope and scope for us to try, and to ensure that we choose the right path." Slade said.
Energy is a necessary input for global agriculture. We need to better understand the interrelationships and roles between them. The report also stressed that scientists in food and agriculture and bioenergy experts need to work more closely together to meet challenges such as water use and environmental protection. If biomass needs to play a major role in future energy systems, then the relationship between bioenergy and food production will become particularly important, and the two cannot be isolated and considered separately.
"Bioenergy may need to be part of a variety of low-carbon energy sources in the future," said Ausilio Bauen, director of bioenergy at the Imperial College's Energy Policy and Technology Center. "Ensuring that bioenergy, food and forests will not compete for land will not be An easy thing to do, but if we use land more efficiently, make it more productive, and make better use of available plant materials, we should be able to feed the growing population while producing bioenergy, and Protect the environment."
