  6. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Energy cost estimates are highly dependent on these assumptions so published cost figures can differ substantially. The presence of wind energy, even when subsidized, can reduce costs for consumers (€5 billion/yr in Germany) by reducing the marginal price, by minimizing the use of expensive peaking power plants. [93]

  7. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies. [2]

  8. Energy harvesting - Wikipedia

    en.wikipedia.org/wiki/Energy_harvesting

    Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition ...

  9. Renewable fuels - Wikipedia

    en.wikipedia.org/wiki/Renewable_fuels

    Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
