alternative energy
(noun)
Energy derived from any renewable source; i.e., energy not from fossil fuels or nuclear fission.
Examples of alternative energy in the following topics:
-
Facultative Phototrophy
- A facultative phototroph can rely on photosynthesis and alternative energy sources to survive and grow.
- They are able to make their own food, and do not need a living energy or carbon source.
- Autotrophs can reduce carbon dioxide to make organic compounds, creating a store of chemical energy.
- Phototrophs, a type of autotroph, convert physical energy from sunlight (in case of green plants) into chemical energy in the form of reduced carbon.
- As one can imagine switching energy sources under varying conditions allows facultative microbes to live in different conditions, in the case of a facultative phototroph it can rely of light other energy sources.
-
New Sources of Energy
- "Energy independence" has thus become an important buzzword in U.S. politics, leading to greater investment in new and alternative sources of energy.
- However, the widespread use of alternative fuel requires more than just scientific research.
- While there are many alternative energy sources to choose from, none of them is perfect, and each has its own supporters and detractors.
- Other alternatives include biofuels such as ethanol and clean coal technologies.
- These wind turbines exemplify one type of a new and alternative energy source.

- 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.

- This highly recommended publication is specifically designed to help businesses of all sizes to reduce their energy needs.

New Energy Sources
- Alternative and renewable energy sources can reduce the environmental impact of energy production and consumption.
- Renewable energy is energy that comes from natural resources, such as sunlight, wind, rain, tides, waves, and geothermal heat, which are all naturally replenished.
- While many renewable energy projects are large-scale, renewable technologies can also be suited to rural and remote areas, where energy is often crucial in human development.
- Ethanol is a quasi-renewable energy source.
- This is because, while the energy is partially generated by non-depletable sunlight, the harvesting process requires vast amounts of energy that typically comes from non-renewable sources.
-
General energy reduction
- Improved insulation can save $800 or more a year in energy costs.
- Determine if the local power company provides sustainable energy alternatives.
- A 2% decrease during the day can cut energy bills by 2.5%.
- Setting the thermostat back 10° at night can cut 15% off energy bills.
- Replace all office light bulbs with energy-efficient alternatives.
-
Lattice Energy
- Lattice energy is a measure of the bond strength in an ionic compound.
- As an example, the lattice energy of sodium chloride, NaCl, is the energy released when gaseous Na+ and Cl- ions come together to form a lattice of alternating ions in the NaCl crystal.
- Alternatively, lattice energy can be thought of as the energy required to separate a mole of an ionic solid into the gaseous form of its ions (that is, the reverse of the reaction shown above).
- Sodium ions (Na+) and chloride(Cl-) ions, depicted in purple and green respectively, alternate in the crystal lattice of solid NaCl.
- This tutorial covers lattice energy and how to compare the relative lattice energies of different ionic compounds.

Suggestions for improving the efficiency of building interiors
- Replace old exit signs with Energy Star rated alternatives.
- Replace all office equipment with energy-efficient alternatives.

- Install low-energy ceiling fans.

Bond Energy
- Bond energy is the measure of bond strength.
- Alternatively, it can be thought of as a measure of the stability gained when two atoms bond to each other, as opposed to their free or unbound states.
- These energy values (493 and 424 kJ/mol) required to break successive O-H bonds in the water molecule are called 'bond dissociation energies,' and they are different from the bond energy.
- The bond energy is the average of the bond dissociation energies in a molecule.
- The bond energy is energy that must be added from the minimum of the 'potential energy well' to the point of zero energy, which represents the two atoms being infinitely far apart, or, practically speaking, not bonded to each other.

Energy in a Simple Harmonic Oscillator
- The total energy in a simple harmonic oscillator is the constant sum of the potential and kinetic energies.
- As the object starts to move, the elastic potential energy is converted to kinetic energy, becoming entirely kinetic energy at the equilibrium position.
- This concept provides extra insight here and in later applications of simple harmonic motion, such as alternating current circuits.
- This total energy is constant and is shifted back and forth between kinetic energy and potential energy, at most times being shared by each.
- All energy is potential energy.

Additional cost and energy saving suggestions for pumps
- A General Motors assembly plant in Flint, Michigan, for example, reduced its energy needs by around 8% after, in part, decommissioning unused air supply systems and ensuring that those that remained worked properly.

- In addition, leaking condensate return lines bring back less condensate to their boiler, thereby forcing the boiler to use more energy to heat up replacement water.
