Green transport refers to any means of sustainable transport with low impact to the environment, and includes human or animal muscle-powered vehicles, low-carbon fueled vehicles, any kind of vehicle using a renewable source of energy for its propulsion. Most common form of green transport are hybrid vehicles. Hybrid vehicles use regular internal combustion engine combined with an electric engine. Biofuel powered vehicles are also beginning to be more popular. They use different form of biofuel like: vegetable oil, biodiesel, or bioalcohol for their propultion.
In common usage public transport is considered a green transport option in comparison with private vehicles, as is car pooling. But some people prefer a definition that does not include public transport or vehicle movements which relies on non-renewable energy.[citation needed]
Green transport includes
- Walking (also called ambulation) is the main form of animal locomotion on land, distinguished from running and crawling. When carried out in shallow waters, it is usually described as wading and when performed over a steeply rising object or an obstacle it becomes scrambling or climbing. The word walk is descended from the Old English wealcan "to roll".
- Bicycling, also called cycling or biking, is the use of bicycles as a means of transport, a form of recreation, or a sport. It is done on roads and paths, across open country or even over snow and ice (icebiking). This sport can be performed with unicycles (unicycling), tricycles (tricycling), quadricycles (quadricycling), and other similar wheeled human-powered vehicles (HPVs)
- A green vehicle is one that is significantly less harmful to the environment than comparable conventional vehicles. Presently, the term is used for any vehicle surpassing the Euro6-norm such as LEVs and ULEVs, and also more informally to California's zero emissions vehicles and other low-carbon emission vehicles. Certain green vehicles may provide a way of sustainable transport.
- Green Vehicles also include:
-
- A solar vehicle is an electric vehicle powered by a type of renewable energy, by solar energy obtained from solar panels on the surface (generally, the roof) of the vehicle. Photovoltaic (PV) cells convert the Sun's energy directly into electrical energy. Solar vehicles are not practical day-to-day transportation devices at present, but are primarily demonstration vehicles and engineering exercises, often sponsored by government agencies.
-
- Wind-powered electric vehicles primarily use wind-turbines installed at a strategic point of the vehicle, which are then converted into electric energy which causes the vehicle to propel.
-
- An electric car is an alternative fuel car that uses electric motors and motor controllers instead of an internal combustion engine (ICE). Currently, in most cases, electrical power is derived from battery packs carried on board the vehicle. Other energy storage methods that may come into use in the future include the use of ultracapacitors, or storage of energy in a spinning flywheel
-
- A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.
Often there can be a sliding scale of green transport depending on the sustainability of the option. Public transport on traditional diesel buses uses less fuel per passenger than private vehicles so is more green than private vehicles, but is not as green as using a solar powered bus. It can often be useful to talk about moving a community towards the ultimate green mode transport outcomes - instead of declaring that they are there if they cross a particular sustainability threshold. Walking across sensitive environments can often cause considerable damage and so is not always the greenest option.
Electric trains and electric buses are another form of green transport categorized to public transport.
Green transportation is for reducing the environmental damage originated in individual's use of cars and light trucks.
