=energy

Get energy use estimates for flights, rail trips, and automobile trips (more coming soon!). BETA from Brighter Planet.

==BETA

This is beta software and subject to change at any time.

==Examples

===Fuel used by a Bentley

?> Energy::AutomobileTrip.fuel_use(:make => 'Bentley', :distance => 500)
=> [how many litres of gas a Bentley uses to drive 500km]

===Fuel used by a Continental Airlines flight

?> Energy::Flight.fuel_use(:airline => 'Continental Airlines')
=> [how many litres of aviation fuel a Continental Airlines flight consumes]

===Fuel used by an Amtrak train

?> Energy::RailTrip.fuel_use(:rail_class => 'intercity', :distance => 500)
=> [how many litres of diesel an intercity uses over 500km]

==TODO

• always provide a conversion of, for example, fuel use in litres to energy use in joules to be true to the intent of the gem
• decide how we expect people to use this gem (maybe it should be more like Carbon and not define its own classes)
• hit impact.brighterplanet.com or energy.brighterplanet.com directly
