The Global Potential of Solar

2015 2050

• Solar is slightly more than 2% of the energy mix in Australia• Solar is less than 1% of energy mix globally• Approximately 500,000 solar homes in US, while 900,000

new homes are built annually• Globally PV solar is expected to become a dominant source

of power generation globally by 2050

Architectural• Knits together divergent networking technologies and administrative

domains (interconnected networks)• Distributed system – failure tolerant, cost efficient• Each layer relies on next lower layer to execute more primitive

functions and provides services to the next higher layer

Cultural/Framework• Government + industry partnership, transition to commercialization• Free and open access to the basic standards• Competitive collaboration for interoperability

Why did the Internet scale?
