The energy sector can have other negative impacts on the food sector when mining for fossil fuels and deforestation for biofuels reduce land for agriculture, ecosystems and other uses. The measurement of the water-energy-food nexus is complex in that the constituent sectors are measured in different units. They also vary both spatially and ...
A negative-calorie food is food that supposedly requires more food energy to be digested than the food provides. Its thermic effect or specific dynamic action —the caloric "cost" of digesting the food—would be greater than its food energy content.
Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
Electric induction stoves are so efficient that they create less pollution than liquified petroleum gas (LPG) even when connected to coal power sources, and are sometimes cheaper. [22] For stews, beans, rice and other foods that can be adapted to electric pressure cookers, the savings are even greater. [23] [better source needed].
The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices. [16]
The fuel, often referred to as electrofuel, stores the energy that was used in the production of the hydrogen. [11] Hydrogen fuel is typically prepared by the electrolysis of water in a power to gas process. To minimize emissions, the electricity is produced using a low-emission energy source such as wind, solar, or nuclear power. [12]
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views and is a long-standing, controversial one in the literature.
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass , which is mainly used for heating , and 3.4% from hydroelectricity .
