It is socially desirable to subsidize a dead-end technology if its environmental externality is small relative to the one of the established technology, if the installed base and/or the strength of the ...

Dynamics Emission For A Polluting Industry

Non-polluting Automobiles

The advantages/disadvantages of energy storage devices, which can provide nonpolluting automobile systems are discussed. Four types of storage devices are identified: electro-chemical (batteries) hydrogen electro-mechanical (flywheels) Molten salt heat storage A high speed flywheel with a small permanent magnet motor/generator has more advantages than any of the other systems and might become a...

The Race for Polluting Permits

International markets for tradable emission permits (TEP) co-exist with national energy taxation. A firm trading emission permits in the international market also pays energy taxes in its host country, thus creating an interaction between the international TEP-market and national energy taxes. In this paper we model that interaction in a framework of a perfectly competitive international TEP-ma...
