Clean Cooking Catalog. Demand Creation. Supply Strengthening. Biomass Energy Sector Planning Guide. Overview The Alliance has developed strategies that both improve utilization of biomass as well as strengthen supply chains and markets for cleaner fuels over time. Five Pillars People traditionally have had a limited choice of fuels, primarily due to availability, affordability, and accessibility.
Improving analysis and evaluation to support partners to select the best fuel options and optimize production and distribution.
These flexible solar cells bring us closer to kicking the fossil-fuel habit
Biomass Ag. Residue, Processed Biomass, etc. Biogas download Fact Sheet. Charcoal Charcoal is charred wood, which has lost all moisture and most volatile contents in the production process.

- Solar energy for electricity and fuels.
It is an energy-dense, light-weight, easy-to-handle, and convenient fuel, which burns without producing much visible smoke other than during lighting. These properties make it a preferred fuel especially in urban and peri-urban areas.
However, the process of turning wood into charcoal usually wastes over half of the available energy in the wood. Stove Types used.

Coal Coal is a black, solid, carbon-rich material found underground and is among the most prevalent fossil fuels. In the household energy sector, coal is used for cooking and heating in countries with abundant coal resources. The World Health Organization recommends that unprocessed coal not be used as a household fuel, due to carcinogenic emissions and toxic elements such as fluorine, arsenic, lead, selenium, and mercury which are not destroyed by combustion. Crop residues Crop residues, including include straws, stems, stalks, leaves, husks, shells, peels, etc.
In the developing world, most agricultural residues that are used for fuel are in their natural state with some pre-treatment like drying and cutting. Materials provided by University of Bath.

Solar-powered hydrogen fuels a step closer: Researchers have used a graphite coating that makes perovskite solar cells waterproof. Retrieved September 22, from www. These quantum dots produce clean hydrogen Journal specific guidelines The following guidelines are journal specific. Authors and referees should note the following guidelines for articles reporting the efficiency of solar conversion devices. Authors should ensure the following information is provided in the main manuscript or supplementary information as appropriate.
Efficiencies should be reported to an appropriate number of significant figures, along with a standard deviation. This also includes presenting error bars on graphs. A sufficient number of samples should be tested, and a sufficient number of trials performed. The 1 Sun AM 1. Full experimental conditions under which the efficiency is measured should be declared.
Special attention should be paid to documenting the active area of the device, the calibration protocol and properties of the illumination including spectral irradiance and intensity.
This may also include as appropriate, but is not limited to, air temperature, use of a glove box, properties and characteristics of the test cell and standardized cell used for calibration, including dimensions and spatial non-uniformity, and calibration and measurement protocols. If incident photon-to-current efficiency IPCE , also referred to as external quantum efficiency EQE measurements are performed , the results should be integrated to a resulting short circuit current that can be compared with 1 Sun AM 1.
The details of how this calculation is done and any correction factors should be clearly defined.
