Improved water, energy, and food security on a global level can be achieved through a nexus approach [17] —an approach that integrates management and governance across sectors and scales. [18] A nexus approach can support the transition to a green economy, which aims, among other things, at resource use efficiency and greater policy coherence ...
An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
Researchers report, based on simulations, how large wind-farm performance can be significantly improved using windbreaks. [ 75 ] [ 76 ] The world's first fully autonomous commercial "airborne wind energy" system (an airborne wind turbine ) is launched by a company.
Dispatchable plants have varying startup times, depending on the technology used and time elapsed after the previous operation. For example, "hot startup" can be performed a few hours after a preceding shutdown, while "cold startup" is performed after a few days of inoperation.
[24] [25] Brazil sugarcane ethanol fuel program success and sustainability is based on the most efficient agricultural technology for sugarcane cultivation in the world, [26] uses modern equipment and cheap sugar cane as feedstock, the residual cane-waste is used to process heat and power, which results in a very competitive price and also in a ...
Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3] Bioenergy can help with climate change mitigation but in some cases the required biomass production can increase greenhouse gas emissions or lead to local biodiversity loss. The environmental impacts of ...
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy ...
Productivity-improving technologies date back to antiquity, with rather slow progress until the late Middle Ages. Important examples of early to medieval European technology include the water wheel, the horse collar, the spinning wheel, the three-field system (after 1500 the four-field system—see crop rotation) and the blast furnace.
