Oceans often act as renewable resources. Sawmill near Fügen, Zillertal, Austria Global vegetation. A renewable resource (also known as a flow resource [note 1] [1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.
Conversely, nations abundant in renewable resources, and the minerals required for renewables technology, are expected to gain influence. [ 230 ] [ 231 ] In particular, China has become the world's dominant manufacturer of the technology needed to produce or store renewable energy, especially solar panels , wind turbines , and lithium-ion ...
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.
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]
Bioplastics called drop-in bioplastics are chemically identical to their fossil-fuel counterparts but made from renewable resources. Examples include bio-PE, bio-PET, bio-propylene, bio-PP, [20] and biobased nylons. [21] [22] [23] Drop-in bioplastics are easy to implement technically, as existing infrastructure can be used. [24]
Today bio-based materials can represent a possible key-strategy to address the significant environmental impact of the construction sector, which accounts for around 40% of global carbon emissions.
