(4) The number of credits obtained in respect of fleets of the 2011 model year that contain alcohol dual fuel vehicles or natural gas dual fuel vehicles and that are available to offset a deficit incurred in respect of a fleet of passenger automobiles or light trucks of the 2012 or subsequent model years must be adjusted with the assumption that all alcohol dual fuel vehicles and natural gas dual fuel vehicles operate only on gasoline or diesel fuel.

(4) Based on the consultation of stakeholders and national experts, as well as expertise electricity, hydrogen, biofuels, paraffinic fuels, natural gas (possibly shale gas), liquefied natural gas (LNG) and liquefied petroleum gas (LPG) were identified as the main alternative fuels with a potential for long-term oil substitution and decarbonisation.

I think there is a natural synergy between renewable energy and natural gas, not only on what was discussed in terms of being the opportunity to balance renewables, but also in the longer term the opportunity is potentially to store renewables, whether it's this idea of power to gas, or even renewable fuels, or renewable natural gas.

In line with the Communication on alternative fuels for road transportation, short term RTD will concentrate on four types of alternative motor fuels that potentially could reach a significant market share: natural gas, synthetic fuels derived from natural gas or heavy residues, biofuels and hydrogen.

More in particular, the focus areas of the investigation will be the exploration, development and production of crude oil and natural gas, the natural gas 'distribution column' in the Netherlands and in Germany, the lubricants supply chain, aviation lubricants, a new technology converting natural gas into fuels, and the refining and marketing of motor fuels in a certain number of European countries (the UK, the Netherlands, Germany, Austria, Luxembourg and France).

I want to use this as an opportunity to point out one other aspect, to simply note the various revenue sources that are identified: personal income taxes, corporate income taxes, taxes on capital corporations, general and miscellaneous sales taxes, harmonized sales taxes, amusement taxes, tobacco taxes, motor fuel taxes, non-commercial motor vehicle licence revenues, commercial motor vehicle licence revenues, alcoholic beverage revenues, hospital and medical care insurance premiums, forestry revenues, conventional new oil revenues, conventional old oil revenues, heavy oil revenues, mined oil revenues, light and medium third oil revenues, heavy third oil revenues, revenues from domestically sold natural ...[+++] gas, revenues from exported natural gas, sales of crown leases, sales of reservations on oil and natural gas lands, oil and natural gas revenues other than those just described, mining revenues, water power rentals, insurance premium taxes, payroll taxes, provincial local government property taxes, race track taxes, revenues from lottery ticket taxes, revenues from games of chance taxes, miscellaneous provincial taxes, provincial revenues from sales of goods and services, local government revenues from sales of goods and services, miscellaneous local government taxes and revenues.
