2. Sustainable energy - Wikipedia

   en.wikipedia.org/wiki/Sustainable_energy

   Various projections of future energy use identify solar PV as one of the main sources of energy generation in a sustainable mix. [64] [65] Most components of solar panels can be easily recycled, but this is not always done in the absence of regulation. [66] Panels typically contain heavy metals, so they pose environmental risks if put in ...

3. Energy efficiency in transport - Wikipedia

   en.wikipedia.org/wiki/Energy_efficiency_in_transport

   The specific energy consumption of the trains worldwide amounts to about 150 kJ/pkm (kilojoule per passenger kilometre) and 150 kJ/tkm (kilojoule per tonne kilometre) (ca. 4.2 kWh/100 pkm and 4.2 kWh/100 tkm) in terms of final energy. Passenger transportation by rail systems requires less energy than by car or plane (one seventh of the energy ...

4. Sustainable transport - Wikipedia

   en.wikipedia.org/wiki/Sustainable_transport

   Sustainable transport is transportation sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport (roads, railways, airways, waterways, canals and

5. Alternative fuel - Wikipedia

   en.wikipedia.org/wiki/Alternative_fuel

   Methanol and ethanol fuel are primary sources of energy; they are convenient fuels for storing and transporting energy. These alcohols can be used in internal combustion engines as alternative fuels. Butane has another advantage: it is the only alcohol-based motor fuel that can be transported readily by existing petroleum-product pipeline ...

6. Carbon-neutral fuel - Wikipedia

   en.wikipedia.org/wiki/Carbon-neutral_fuel

   However, when compared with electrification of the vehicle fleet – a key advantage of such biofuel is the avoidance of the costly distribution of large amounts of electrical energy (as is required to convert existing vehicle fleets to battery electric technology), therein allowing for the re-use of the existing liquid-fuel transportation ...

7. Low-carbon economy - Wikipedia

   en.wikipedia.org/wiki/Low-carbon_economy

   Most of the sustainable energy is renewable energy. Therefore, another term for energy transition is renewable energy transition. The current transition aims to reduce greenhouse gas emissions from energy quickly and sustainably, mostly by phasing-down fossil fuels and changing as many processes as possible to operate on low carbon electricity ...

8. Renewable energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_energy

   Renewable energy is also distinct from sustainable energy, a more abstract concept that seeks to group energy sources based on their overall permanent impact on future generations of humans. For example, biomass is often associated with unsustainable deforestation .
