Showing results for: Renewable energy
This report summarises research from scientific, policy and industrial experiences on energy use in the EU food sector. It acknowledges that while the EU has made progress in incorporating renewable energy across the economy, the share of renewables in the food system remains relatively small. The report discusses the way ahead and highlights the main challenges to be faced in decreasing energy use and in increasing the renewable energy share in the food sector.
A new paper published in Environmental Science and Technology finds that measures to mitigate agricultural GHG emissions potentially risk increasing global hunger more than the impacts of climate change on crop yields itself. The study draws upon global models to quantify: a. the impact of climate change on yields in the absence of mitigation, b. the impact of bionergy production (as one mitigation measure) on competition for land and associated food prices and c. finally, the costs associated with mitigating the impacts of climate change by introducing a carbon tax. Introduction of this tax is assumed to lead to increase in use of renewable fuels (wind, power, geothermal, bionenergy) and ‘abatement from non energy sources’ – which presumably includes agriculture although they do not specify what sort of abatement this would be.
A new green energy initiative has been launched by the Japanese meat processor NH Foods. Their Global Water Engineering (GWE) Cohral plant (in Australia)will extract green energy biogas from the waste water stream of production, replacing millions of dollars’ worth of natural gas currently consumed by the company factory. It is reported that the effect of burning the methane will save the equivalent of 12,000 tonnes of CO2, equivalent to removing 2,700 cars from the road.
The first progress report of A Better Retailing Climate initiative has been published. It describes how retailers since 2005 have improved their performance against the environmental targets set out in the initiative, and that they have:
The green economy is widely seen as a potential solution to current global economic and environmental crises, and a potential mechanism by which sustainable development might be achieved in practice.
The World Business Council for Sustainable Development (WBCSD) has released a report on the water, food and energy nexus, entitled “Co-optimizing Solutions: Water and Energy for Food, Feed and Fiber.”
A recent study from the Tyndall Centre for Climate Change Research finds that the UK is failing to make the most of its abundant biomass potential. The researchers found that almost half, up to 44%, of the UK's energy could be produced within the country by using biomass sources, including household waste, agricultural residues and home-grown biofuels. The UK currently produces about half of the food it consumes, and is ~60% ‘self-sufficient’. Although complete food self-sufficiency is not the current goal, the researchers stress that improved food system adaptive capacity is important if the UK is to cope with future stresses in the food system.
The Danish Council of Ethics has launched an English version of its report on the ethical challenges associated with bioenergy production. The “Report on bioenergy, food production, and ethics in a globalised world” considers the production of bioenergy in a situation characterized by several major global crises - energy, food, climate and natural resources. Some forms of bioenergy may be a tool in battling the energy crisis and the climate crisis. However, growing energy crops may compete with food production and nature for scarce resources and thereby counter solutions to the equally acute crises concerning food and natural resources. The main focus of the report is thus on the ways bioenergy competes with food production and nature for scarce resources. The Council focuses also on the values that determine the choice of strategy in regard to countering these four challenges and points out that ethical deliberations should be more made more explicit in political decision-making related to major global crises.
The European Commission has announced funding for three major research projects designed to promote innovation in the meat and livestock sector. The funding will come from EU’s outgoing Seventh Framework Programme for Research and Technological Development.
A video recording of Al Gore's public lecture for the Oxford Martin School is now available on the Oxford Martin School website here.
In his lecture Gore outlined the challenges presented in his latest book, ‘The Future’, ranging from climate change and wealth inequality to biotechnology and the loss of jobs to automation.
Additional events arranges by the Oxford Martin School can be found here.
A new centre has been set up in the UK, which aims to reduce the energy used across food production, taking a whole system approach. The RCUK Centre for Sustainable Energy Use in Food Chains (CSEF) will examine where and how to make savings in food production: its research outputs are intended to support energy efficiency policy and contribute to cutting carbon use and GHG emissions. One of its primary research themes is the simulation of energy and resource flows in the food chain, from manufacture and transport of food through to the energetic requirements of refrigeration in supermarkets.
Anaerobic digestion (AD) is the process of energy production through the production of biogas from agricultural and other organic waste. This book provides a broad introduction to AD and its potential to turn agricultural crops or crop residues, animal and other organic waste, into biomethane.
This research quantifies the short-term costs of delaying action when confronted with the climate challenge. It concludes that the later climate policy implementation starts, the faster -- hence the more expensive -- emissions have to be reduced if states world-wide want to achieve the internationally agreed target of limiting global warming to 2 degrees above pre-industrial level.
