ICT Growth proportional to Data Growth/Internet penetrationBetween 2010 and 2011 Almost all countries increased their IDI values but.. developed countries have twice the IDI value of the developing ones

Global Data consumption is growing exponentially:

Typical Operating ExpensesElectricity prices & Fuel PricesElectricity prices have high correlation with world crude oil pricesHigher proportion of thermal energy being powered through crude oil

In Sri Lanka future electricity prices will be more correlated with coal pricesNoracholai, SampurThermal Energy (SL) Now & FutureHigher portion of thermal power primarily through fuel oil.Sri Lanka identified coal as a low cost energy source Eg: Norocholai (900MW), Sampur (500MW)Risk of increase in pollutionAnnie HazlehurstJoint MBA / MS Environment & Resources CandidateStanford Graduate School of Business

Re-use existing InfrastructureEg: battery bank

Note: Wind is more efficient than solar cells but much more scarce based on the location of the site.

ICT solutions and Infrastructure design can be optimised through active collaboration

Renewable Energy is cost-beneficial and MUST supplement grid powerThank you !
