Solar fuels can be produced via direct or indirect processes. Direct processes harness the energy in sunlight to produce a fuel without intermediary energy conversions. Solar thermochemistry uses the heat of the sun directly to heat a receiver adjacent to the solar reactor where the thermochemical process is performed.
Wind turbines on County Leitrim's Corrie Mountain Ireland renewable electricity production by source. Under the original 2009 Renewable Energy Directive Ireland had set a target of producing 16% of all its energy needs from renewable energy sources by 2020 but that has been updated by a second Renewable Energy Directive whose targets are 32% by ...
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.
Another area of research within artificial photosynthesis is the selection and manipulation of photosynthetic microorganisms, namely green microalgae and cyanobacteria, for the production of solar fuels. Many strains produce hydrogen naturally. [66] Algae biofuels such as butanol and methanol have been produced at various scales. This method ...
Poolbeg Generating Station, a fossil gas power station owned by the semi-state electricity company, the ESB Group. Ireland is a net energy importer. Ireland's import dependency decreased to 85% in 2014 (from 89% in 2013). The cost of all energy imports to Ireland was approximately €5.7 billion, down from €6.5 billion (revised) in 2013 due mainly to falling oil and, to a lesser extent, gas ...

Compared to the previous year, biomass, solar and wind changed their production by +4.8%, -3.1% and -1.7%, respectively, while weather permitting hydro power decreased by 10.3%. Wind and solar combined generated more energy than nuclear in 2016 (see pie-chart). Nuclear decreased production by 7.7%, while electricity generation from natural gas ...
Any fuel produced from agricultural produce or organic waste is a biofuel. Humans have used biofuels since time immemorial — for example, burning wood and manure for cooking, heating and light.
