This category is intended for non-commercial scientific, educational, and governmental references to biomass and biofuel. Before submitting a site to this category or its subcategories, be sure to read the related descriptions. Failure to submit to the most specific and appropriate category can delay the consideration of your submission. Information on energy itself, but not primarily relating to renewable energy technologies, belongs in the main category on Science/ Technology/ Energy. Further, content for conferences, organizations and publications should be submitted to the appropriate category which can be found from the top level of Energy at Science/ Technology/ Energy. Some educational sites might be better listed in Kids_and_Teens/ School_Time/ Science/Environment/ Renewable_Energy/ or Science/ Technology/ Energy/ Education/. Please compare categories and choose the most appropriate for your submission. Commercial sites that have substantial scientific or non-commercial informational content might be listed here however, please review categories under Business for potentially more appropriate categories before you submit. See for example: Business/ Energy_and_Environment/ Renewable and the category description Information on renewable energy itself, but not primarily relating to biological energy technologies, belongs in the main category on Science/ Technology/ Energy/ Renewable/, not under Biomass and Biofuels.
This category contains non-commercial scientific, educational, and governmental references to biomass and biofuel. Biomass is organic non-fossil material. It comprises the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes into substances such as coal or petroleum. Solid biomass comes in different forms including what comes directly from the “producers” (grass, trees, shrubs, crop husks, etc.) and that which comes as waste from the animals that consume the producers (droppings or dung from animals and waste from humans). Biofuel is any fuel that originates from biomass. The three classes of biomass used for combustion are solid (e.g. wood, dried plants and animal waste), liquid (e.g. ethanol, methanol and vegetable oil) and gaseous (e.g. bio-methane and hydrogen).

Information on renewable energy itself, but not primarily relating to home-made power, belongs in the main category on Science/ Technology/ Energy/ Renewable/.

Information for people interested in making their own power at home. There is a primary focus on electricity generation using renewable energy resources such as windmills, small-scale hydroelectric systems, photovoltaics and other solar technologies. Includes personal web pages describing personal experiences setting up home power systems.

Information on renewable energy itself, but not primarily relating to water energy sources, belongs in the main category on Science/ Technology/ Energy/ Renewable/.

Hydropower is energy obtained from flowing water. The most common source of hydropower is the dam however, it can be directly used as a mechanical force or a heat source or heat sink. In some regions (such as eastern Canada) "hydro" is a synonym for "electricity." Look for "electricity" in other categories.

Information on renewable energy itself, but not primarily relating to ocean energy sources, belongs in the main category on Science/ Technology/ Energy/ Renewable/.

This category contains sites that have content on the various ways of gathering energy from the oceans including a subset of hydro sources.

Information on renewable energy itself, but not primarily relating to solar energy technologies, belongs in the main category on Science/ Technology/ Energy/ Renewable/.

Please submit sites relating to solar and renewable energy only. This category is generally for non-commercial, education, and government references sites.

Business/Product sites dealing with solar and renewable energy, selling of solar and renewable energy products, and commercial sites linking to these types of sites should be submitted to the category Business: Energy: Renewable: Solar.

Solar power harnesses energy from the Sun. We obtain electrical energy from photovoltaic cells that convert sunlight. We obtain thermal energy from the sun either directly or indirectly through systems that collect the heat and transfer it to other things such as air or water. In the most formal sense “solar panel” refers to devices that harness thermal energy from the sun and transfer it to a medium such as air or water. Further, photovoltaic cells, solar cells, photovoltaic panels or PV panels refer to devices that convert sun light energy into electrical energy. However, you will often find common language references of both kinds of devices as “solar panels”. This category contains non-commercial, scientific and educational references to solar energy science and engineering (technology) and the advancement of using solar energy by mainstream society. Topics include solar electrical energy and solar thermal energy technologies.

Please only submit sites here if they span more than one aspect of energy technology.  If the subject is specific to a field covered by another sub-category of Technology: Energy: Renewables, such as Hydro, please submit there instead.

This category is for blogs, administered specifically to keep articles and comments on the topic of technological aspects of renewable energy.

Information on renewable energy itself, but not primarily relating to wind energy technologies, belongs in the main category on Science/ Technology/ Energy/ Renewable/.

Windmills are devices for taking power from the wind, and converting it to other forms of energy which may be applied to specific tasks. There are 3 main categories of windmill:
  • "traditional" English or Dutch style windmills, mostly used for grinding or drainage
  • windpumps, (normally made from metal) used throughout the world for pumping water (and what most Americans think of when they talk of windmills)
  • wind turbines used for generating electricity
