Examples of energy independence in the following topics:
-
- Likewise, the more efficient and energy-independent a nation's businesses become, the less the government has to spend on expanding or building more electrical power plants.
- For more information about sustainable micro-energy sources check out: www.clean-energy-ideas.com, www.alternative-energy-news.info and www.eere.energy.gov/greenpower.
- You can also download the free booklet, The Lean and Energy Toolkit at www.gov/lean/toolkit/LeanEnergyToolkit.pdf.
- This highly recommended publication is specifically designed to help businesses of all sizes to reduce their energy needs.
-
- "Energy independence" has thus become an important buzzword in U.S. politics, leading to greater investment in new and alternative sources of energy.
- Two of the best known and least scientifically controversial new energy sources are solar power and wind power.
- This is not the first time the idea of greater energy independence has become popular in U.S. policy and politics.
- These wind turbines exemplify one type of a new and alternative energy source.
- Describe the challenges facing those attempting to shift the United States away from non-renewable sources of energy
-
- Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis.
- These energized electrons are transported by "energy carrier" molecules, which power the light-independent reactions.
- In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules.
- The light-independent molecules depend on the energy carrier molecules, ATP and NADPH, to drive the construction of new carbohydrate molecules.
- In addition, several enzymes of the light-independent reactions are activated by light.
-
- State-specific energy-efficiency incentive programs also play a significant role in the overall energy policy of the United States.
- The Federal Department of Energy was started with steps planned toward energy conservation and more modern energy producers.
- This energy is used for transport, industry, and domestic use.
- Renewable energy accounted for about 8% of total energy consumption in the United States in 2009.
- It was estimated by the Energy Information Administration that in 2007 primary sources of energy consisted of petroleum (36.0%), coal (27.4%), and natural gas (23.0%), amounting to an 86.4% share for fossil fuels in primary energy consumption in the world.

- Activation energy is the energy required for a reaction to occur, and determines its rate.
- Since these are energy-storing bonds, they release energy when broken.
- Free energy diagrams illustrate the energy profiles for a given reaction.
- However, the measure of the activation energy is independent of the reaction's ΔG.
- This figure implies that the activation energy is in the form of heat energy.
-
- Magnetic field stores energy.
- The energy density is given as $u = \frac{\mathbf{B}\cdot\mathbf{B}}{2\mu}$.
- For linear, non-dispersive, materials (such that B = μH where μ, called the permeability, is frequency-independent), the energy density is:
- Energy density is the amount of energy stored in a given system or region of space per unit volume.
- Energy is "stored" in the magnetic field.
-
- The human body converts energy stored in food into work, thermal energy, and/or chemical energy that is stored in fatty tissue.
- Conservation of energy implies that the chemical energy stored in food is converted into work, thermal energy, or stored as chemical energy in fatty tissue, as shown in .
- Energy consumed by humans is converted to work, thermal energy, and stored fat.
- Approximately 20 kJ of energy are produced for each liter of oxygen consumed, independent of the type of food.
- Energy consumed by humans is converted to work, thermal energy, and stored fat.
-
- Potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position.
- This work is stored in the force field as potential energy.
- The more formal definition is that potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position.
- If the work for an applied force is independent of the path, then the work done by the force is evaluated at the start and end of the trajectory of the point of application.
- In the case of a bow and arrow, the energy is converted from the potential energy in the archer's arm to the potential energy in the bent limbs of the bow when the string is drawn back.
-
- Electric potential energy results from forces between charges; potential difference is the energy needed to move a charge from point A to B.
- Electric potential energy is a type of potential energy that results from Coulomb forces.
- It may represent a source of energy, or lost, stored or used energy.
- Potential difference is independent of path taken from one point to another, and may be measured by any of a number of instruments .
- When a charge q moves from point A to point B, the potential difference is independent of path taken.
-
- Light-dependent reactions, which take place in photosystem I and II, convert solar energy into NADPH and ATP.
- The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
- Light energy is converted into chemical energy in a multiprotein complex called a photosystem.
- That energy is transmitted to the PSI reaction center.
- Cyclic phosphorylation is important to maintain the right proportions of NADPH and ATP, which will carry out light-independent reactions later on.
