Energy conservation
Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques.
Even though energy conservation reduces energy services, it can result in increased financial capital, environmental quality, national security, and personal financial security.[1] It is at the top of the sustainable energy hierarchy.Some countries employ energy or carbon taxes to motivate energy users to reduce their consumption. As detailed in the book, Green Illusions, carbon taxes can allow consumption to shift to nuclear power and other alternatives that carry a different set of environmental side effects and limitations. Meanwhile, taxes on all energy consumption stand to reduce energy use across the board, while reducing a broader array of environmental consequences arising from energy production. The State of California employs a tiered energy tax whereby every consumer receives a baseline energy allowance that carries a low tax. As usage increases above that baseline, the tax increases dramatically. Such programs aim to protect poorer households while creating a larger tax burden for high energy consumers.One of the primary ways to improve energy conservation in buildings is to use an energy audit. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s). This is normally accomplished by trained professionals and can be part of some of the national programs discussed above. In addition, recent development of smartphone apps enable homeowners to complete relativily

    A 2kilogram block is released from rest at the top of a curved incline in the shape of a quarter of a circle of radius R. The block then slides onto a horizontal plane where it finally comes to rest 8 meters from the beginning of the plane. The curved incline is frictionless, but there is an 8newton force of friction on the block while it slides horizontally. Assume g = 10 meters per second2.…

    With energy being a scarce resource, people across the world need to look at lifestyle changes to protect the environment for future generations. Anything from driving less to turning off a light in a room can help the cause. Conservation methods take thought, commitment, and changes to everyday lives to make a difference. In order to conserve energy, consumers need to be aware of their daily usage and find ways to cut the usage down. Conservation of energy includes using less gasoline, electricity, and non-renewable resources. It also involves finding and producing alternative energy, recycling and home improvements. Not all methods of energy conservation will negatively impact the daily routines of people. With a little consideration and dedication to reduce energy consumption, everyone can do their part.…

    Energy Transfers

    The nucleotide ATP (adenosine triphosphate) maintains both catabolic and anabolic reactions. Catabolic reactions e.g. respiration are where larger molecules are broken down into smaller ones with energy being released, and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions. To release energy, ATP is hydrolysed into ADP and Pi (an inorganic phosphate) which releases energy that can be used for energy requiring reactions such as photosynthesis. However to maintain the organisms anabolic reactions, ATP must be continually synthesised by condensation reactions where ADP is added onto a phosphate molecule. This process is helped by energy transferred from catabolic reactions such as respiration and occurs in three ways: photophosphorylation, oxidative phosphorylation and substrate-level phosphorylation. Photophosphorylation takes place in chlorophyll- containing plant cells during photosynthesis, oxidative phosphorylation occurs in the mitochondria and animal cells during electron transport, and substrate- level phosphorylation occurs in plant and animal cells when phosphate groups are transferred from donor molecules to ADP to make ATP e.g. when pyruvate is formed at the end of glycolysis.…

    A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster 's speed and height. Simply put, the higher an object is off the ground, the more potential energy it has - that is, potential to gain speed as it falls. As it falls toward the ground, that potential energy changes to kinetic energy, or energy of motion. The sum of the two types of energy is constant, but a roller coaster must maintain an adequate balance of potential and kinetic energies to deliver a thrilling ride.…

    Fats, proteins, and carbohydrates are sources of energy for the body. Although carbohydrates are the largest source of energy, fats and proteins, however are just important, they contain essential amino chains not found in carbohydrates and are critical to Adenosine Triphosphate (ATP) manufacturing on a cellular level. ATP takes the chemical energy from the food to the mitochondria to transform it into energy for the cells. (Dictionary.com Unabridged definition, 2013) Without essential fatty acids the mitochondria will not produce enough energy to maintain a healthy body. The mitochondria are long or round bodies that are found in the cytoplasm of a cell that produce energy from the ATP using the stored food. (Karp, 2008) Fatty acids also play a vital role in energy production. Functional energy is derived from fats and proteins which are vital for tissue repair as well as the support of the immune system.…

Each trophic level shows how energy and biomass flow through a food chain however it is eventually lost as heat. These levels consist of: biomass of producers, those consumed, and those not consumed. The first trophic level has the producers which graze the food chain, grazers consist of the second level, then carnivores feed on the second level and continues on.…
