Sustainable Energy ... Green Energy is energy that can be extracted, generated, and/or consumed without any significant negative impact to the environment...
Biological Pest Control ... Biological control is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Natural enemies of insect pests, also known as biological control agents; and include predators, parasitoids, and pathogens...
Nematode ... One group of carnivorous fungi, the nematophagous fungi, are predators of soil nematodes. They set enticements for the nematodes in the form of lassos or adhesive structures...
Electric Boat ... It took more than 30 years of battery and motor development before they began to be deployed in any numbers. In 1886 an electric boat crossed the English Channel both ways in 8 hours...
Organic Food ... The weight of the available scientific evidence has not shown a significant difference between organic and more conventionally grown food in terms of safety, nutritional value, or taste. For the vast majority of human history, agriculture can be described as organic; only during the 20th century was a large supply of new synthetic chemicals introduced to the food supply...
Compressed Air Energy Storage ... Isothermal compression and expansion approaches attempt to maintain operating temperature by constant heat exchange to the environment... The theoretical efficiency of isothermal energy storage approaches 100% for perfect heat transfer to the environment...
Solar Water Heating ... In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow...
Terraforming Of Mars ... Future population growth and demand for resources may necessitate human colonization of objects other than Earth, such as Mars, the Moon, and nearby planets. Space colonization will facilitate harvesting the Solar System's energy and material resources...
Environmental Impact Of Agriculture ... At the same time, agriculture has been shown to produce significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, but also by altering the Earth's land cover, which can change its ability to absorb or reflect heat and light, thus contributing to radiative forcing. Land use change such as deforestation and desertification, together with use of fossil fuels, are the major anthropogenic sources of carbon dioxide; agriculture itself is the major contributor to increasing methane and nitrous oxide concentrations in earth's atmosphere...
Biofuel ... Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn or sugarcane. Cellulosic biomass, derived from non-food sources such as trees and grasses, is also being developed as a feedstock for ethanol production...
Terraforming Of Venus ... Construction of a suitably large solar shade is a daunting task. The size of the shade would be four times the diameter of Venus itself if at the L1 point...
Microgeneration ... The power plant In addition to the electricity production plant (e.g. wind turbine, solar panel, .), infrastructure for energy storage and power conversion and a hook-up to the regular electricity grid is usually needed and/or foreseen...
Genetically Modified Organism ... In 1986, field tests of bacteria genetically engineered to protect plants from frost damage (ice-minus bacteria) at a small biotechnology company called Advanced Genetic Sciences of Oakland, California, were repeatedly delayed by opponents of biotechnology. In the same year, a proposed field test of a microbe genetically engineered for a pest resistance protein by Monsanto Company was dropped...
Renewable Energy Commercialization ... There are some non-technical barriers to the widespread use of renewables, and it is often public policy and political leadership that helps to address these barriers and drive the wider acceptance of renewable energy technologies. As of 2010, 98 countries have targets for their own renewable energy futures, and have enacted wide-ranging public policies to promote renewables...
Space-based Solar Power ... SBSP would differ from current solar collection methods in that the means used to collect energy would reside on an orbiting satellite instead of on Earth's surface. Some projected benefits of such a system are: Higher collection rate: In space, transmission of solar energy is unaffected by the filtering effects of atmospheric gasses...
Energy Storage ... All forms of energy are either potential energy (e.g. Chemical, gravitational, electrical energy, etc.) or kinetic energy (e.g...
Plant Breeding ... Plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is now practiced worldwide by individuals such as gardeners and farmers, or by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers...
Organic Clothing ... Benefits Authentic organic fabrics and clothing can help the environment in a number of ways, such as: Manufacture of chemicals is not required Chemical residues are not entered accidentally into the environment Humans and animals are not exposed to chemicals When the fabric is finished with chemicals are not returned to the earth in landfill, or enter into recycling process...
Nature ... The word nature is derived from the Latin word natura, or "essential qualities, innate disposition", and in ancient times, literally meant "birth". Natura was a Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord...
