What practical engineering of human behavior would save humankind the most energy?
Buses are not very energy efficient per head. Cars beat them.grafica said:i think instead of using private vehicles each can use public vehicles such as electric trains and buses for transportation...
I wonder if busses numbers are skewed by the type of driving they do?mheslep said:Buses are not very energy efficient per head. Cars beat them.

Sure I expect all those stops and starts are part of it; then there's the driving to and from the bus barn completely empty, and finally the unavoidable percentage of driving on the route w/ low or non-existent passenger loads. So if one sees an existing bus going down the road, certainly its better to jump on it rather than get in the car to save energy, but one can not say the same about buying the next new bus.russ_watters said:I wonder if busses numbers are skewed by the type of driving they do?
russ_watters said:What I mean, though, is did they compare busses driving in the citiy to cars driving in the city or just busses to cars.
Yes of course. The 'Vanpool' category, large multi-passenger vehicles that go only from point A to B, park, and then return the passengers back again, is far, far more efficient as a people mover than any other kind of transport at 1322 BTUs per passenger mile, including motorcycles.Mech_Engineer said:The comparison is not exactly apples to apples either, because buses stop every quarter to half-mile or so at a bus stop, where as a car goes point a-b with less stops, other than stop lights they both stop at.
I'd bet a charter bus carrying 50 people going down the highway would get better energy per person than a single car carrying one or two people.
There are several ways you can decrease your energy consumption, such as: turning off lights and electronics when not in use, using energy-efficient appliances, properly insulating your home, and using alternative energy sources like solar or wind power.
Modifying our energy consumption is crucial for several reasons. Firstly, it helps reduce our carbon footprint and mitigate the effects of climate change. Additionally, it can save us money on energy bills and promote a more sustainable future for generations to come.
By modifying our energy consumption, we can reduce our reliance on fossil fuels, which are major contributors to air and water pollution. This, in turn, can help improve air quality and protect natural habitats and wildlife. Additionally, using renewable energy sources can help lower greenhouse gas emissions and slow down the rate of climate change.
Technology can play a significant role in energy consumption modification. For example, smart home devices can automatically adjust energy usage based on occupancy and usage patterns. Energy-efficient appliances and vehicles, as well as renewable energy technologies, are also key in reducing our overall energy consumption.
Businesses and industries can contribute to energy consumption modification by implementing energy-efficient practices and investing in renewable energy sources. They can also promote education and awareness about energy conservation among their employees and customers. Additionally, businesses can partner with organizations and governments to develop and implement sustainable energy policies.
