Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

Never too late for a Course-Correction

Report  pitches Solar Power as a more pragmatic fuel than ethanol-blended petrol

 

Since I could not find this article online, I reproduce below, what seems like the  original source :


IEEFA: Solar recharging of electric vehicles is a far more efficient use of land than ethanol crops for blended fuel in India 


23 March (IEEFA):

India’s 2025 target for 20% ethanol blending in petrol requires large increases in ethanol from sugar and grains. A new report by the Institute for Energy Economics and Financial Analysis (IEEFA) shows that generating solar energy to recharge electric vehicle (EV) batteries would be a far more efficient use of land than growing crops for ethanol.


The report shows that matching the distance driven by EVs recharged from one hectare of solar generation would require ethanol derived from up to 251 hectares of sugar cane or 187 hectares of maize – even accounting for losses from electricity transmission, battery charging and grid storage.


Enhancing goals for EV uptake could meet many of the goals set out in India’s Roadmap for Ethanol Blending – cutting emissions and air pollution, supporting domestic agricultural demand, and reducing the drain on India’s foreign exchange by limiting oil imports – while using a fraction of the land, according to the report.









The ethanol-blending target, also known as E20, will require a doubling of ethanol from sugar and quadrupling of ethanol from grains in just four years, with significant land use implications.


While surpluses may be sufficient for the component of new ethanol earmarked for sugar, up to 30,000  sq km of land may be needed for the additional ethanol planned for grains (maize).


“This large-scale diversion of agricultural land for ethanol blending conflicts with other key priorities for food production, water use and renewable energy adoption,” says report author and guest contributor Dr Charles Worringham.


“While the government’s promotion of ethanol blending in petrol may seem like a way to ease the burden of soaring crude oil prices, it further increases the pressure on agricultural land just as the war in Ukraine threatens the world’s grain supply. This intensifies the competition between energy and food and raises the stakes for wise land use in India significantly.


Large-scale diversion of agricultural land for ethanol blending conflicts with other key priorities


“Although Russia has an 11% share of global oil exports, 26% of wheat exports come from Russia and Ukraine, and 16% of corn exports. In the end, food trumps energy for claims on arable land if the food supply comes under pressure.”


Future threats to agricultural production in South Asia have been reinforced by the recent IPCC Working Group II report, underlining the critical importance of wise land use in India.


“A re-evaluation of the ethanol-blending policy and alternatives is needed urgently, given that its targets have been brought forward to 2025 from 2030,” says Worringham.


The report builds on IEEFA’s recent examination of the interplay between the energy transition and land use in India, and of India’s potential in agrivoltaics, comparing the land required to meet the ethanol-blending target with land needed for solar generation.


The report contains three key recommendations:

·         Exploring the option of enhancing India’s EV adoption strategy as an alternative to blended fuel.


·         Undertaking a critical review of the ethanol-blending plans with efficient land use as an important consideration.


·         Pausing measures to further implement the ethanol-blending policy while such a review is conducted.

MY  TAKE  :

 

Dear Shri  Tomarji   Shri  Gadkariji  :

 

Only last week , I sent to you following e-mail , urging you to “ Re-consider “ our

Ethanol-Blending policy :


Ø  Is Gadkariji having second thoughts ? …………………. [ 26 April 2022 ]

 

-           Where , I suggested as follows :


What could / should be done ?

Ø  Reduce intake of sugar in daily food intake ( through education and

    steep price rise )


Ø  Reduce Petrol vehicles and quickly change-over to Electric Vehicles,

    thereby reducing petrol demand

    

Ø  Reduce ethanol blending – thereby reducing ethanol production /

    sugarcane diversion

 

What made me suggest this was based on my following 5 YEAR old e-mail :

Ø  Not a straightforward Answer !.................  [ 03 March 2017 ]

 

Extract :


      #   It takes 1700 gallons of water to produce one gallon of ethanol 


      #   Biofuels use an astonishing 1.78 million times more water than Solar to

           generate the same amount of energy

          

     #  Sugarcane , one of the biofuel industry’s “ success stories “, converts

         just 0.38 per cent of sunlight into biomass 

               

          #   In the end, the solar-to-ethanol conversion ratio for sugarcane is

               just 0.13 per cent , according to  “ Scientific American “

               

          #  The average Solar Panel is 123 TIMES more efficient in converting sunshine

               into usable energy


         #  Concentrating photovoltaic { CPV } can turn about 40 per cent of the

             sunshine into electricity, which makes it THREE HUNDRED TIMES more

             efficient than sugarcane ethanol biofuel

             

        #  SOLAR IS ANYWHERE FROM 123 TO 550 TIMES MORE EFFICIENT THAN

            BIO- FUELS


       #  SOLAR CHP ( COMBINED HEAT AND POWER ) CAN CONVERT SUNSHINE 550

           TIMES MORE EFFICIENTLY THAN SUGARCANE CAN

     

          ==================================================

 Dear Shri Tomarji – Shri Gadkariji  ,


Whereas cars can – and will – survive without ETHANOL, people ( mostly in rural

India ), are likely to die without WATER !


It is not too late to re-consider ETHANOL BLENDING policy
