    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 ...

  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 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 ...

    en.wikipedia.org/wiki/Low-carbon_economy

    An energy transition (or energy system transformation) is a major structural change to energy supply and consumption in an energy system. Currently, a transition to sustainable energy is underway to limit climate change. Most of the sustainable energy is renewable energy. Therefore, another term for energy transition is

  9. Low-carbon electricity - Wikipedia

    en.wikipedia.org/wiki/Low-carbon_electricity

    Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...
