  2. Micro combined heat and power - Wikipedia

    en.wikipedia.org/wiki/Micro_combined_heat_and_power

    Some of the heat sources and fuels that are being considered for use with micro-CHP include: natural gas, LPG, biomass, vegetable oil (such as rapeseed oil), woodgas, solar thermal, and lately also hydrogen, as well as multi-fuel systems. The energy sources with the lowest emissions of particulates and net-carbon dioxide include solar power ...

    Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2]

  5. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  6. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]

  7. Microgeneration - Wikipedia

    en.wikipedia.org/wiki/Microgeneration

    Microgeneration technologies include small-scale wind turbines, micro hydro, solar PV systems, microbial fuel cells, ground source heat pumps, and micro combined heat and power installations. [1] These technologies are often combined to form a hybrid power solution that can offer superior performance and lower cost than a system based on one ...

  9. Biorefinery - Wikipedia

    en.wikipedia.org/wiki/Biorefinery

    The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)".
