The Transition: Net Zero, Green Hydrogen and a Just Transition

In one line

The statutes needed for a transition already exist; what is missing is a rule allocating the cost of intermittency, a legal home for storage, an obligation to clean up at the end of life, and a plan for the districts that live on coal.

The comparison, on stated axes

MU asks for compare and contrast, so give the axes and then the verdict on each.

Depletion. Conventional sources are stocks; every unit used is gone. Non-conventional sources are flows; only the equipment is consumed. Verdict: decisive for the flows.

Emissions at the point of use. Combustion produces particulates, oxides of sulphur and nitrogen, ash and carbon dioxide. Wind and solar produce none. Nuclear produces no combustion emissions and produces waste instead. Verdict: decisive for the flows and for nuclear on carbon.

Land. Density is a merit of the stocks. Diffuse energy means the highest land requirement per unit of output belongs to the flows, and large hydro submerges. Verdict: for the stocks, and this is the axis students most often get backwards.

Water. Thermal and nuclear stations need cooling water and compete with irrigation; wind and solar photovoltaic need almost none; hydro depends entirely on the river. Verdict: for the flows, except hydro.

Reliability and system cost. Stocks are despatchable; flows are not, and the balancing they require is a cost the system bears. Verdict: for the stocks, on present technology.

End of life. A mine has closure and reclamation obligations; a well has plugging and abandonment rules under section 6(2) of the Oilfields Act; a reactor has decommissioning under the atomic energy framework. A solar module and a wind blade have none. Verdict: for the stocks, which is not what the question expects and is the honest answer.

Maturity of law. Every conventional source has a developed statute; the flows are governed by a handful of enabling provisions and a great deal of regulation. Verdict: for the stocks.

So the comparison is not one-sided. On depletion and emissions the flows win decisively, and those two are what sustainability means. On land, reliability, end of life and legal maturity the stocks are ahead. A candidate who states it that way is doing what the question asks and is not merely cheering.

What the law already has

The transition does not need a new statute to begin, and an answer should say which provisions do the work.

A planning duty. Section 3(1) of the Electricity Act requires the National Electricity Policy and tariff policy to be made for development of the power system based on optimal utilisation of resources such as coal, natural gas, nuclear substances or materials, hydro and renewable sources of energy, and section 3(4) requires a National Electricity Plan notified once in five years after a published draft and public objections. Section 73(a) puts on the Authority the co-ordination of planning agencies for the optimal utilisation of resources to subserve the interests of the national economy and to provide reliable and affordable electricity for all consumers.
