Why Renewables ?
“Today, the utilization of renewable energy for power generation is both an environmentally friendly choice and a smart economic decision” – International Renewable Energy Agency (IRENA 2018).
Onsite generation and utilization of electricity is more efficient than grid-supplied electricity as transmission and distribution losses and infrastructure costs are eliminated from the value chain – Natural Resources Canada (NRCAN 2018).
Why Solar and Wind?
“The most attractive renewable energy sources, from a cost perspective, are onshore wind and solar PV” (Forbes, 2019).
“Today’s wind energy is the lowest-cost source of new electricity in Alberta” – Canadian Wind Energy Association (2019).
Solar and wind make up ~90% of all renewable resource with potential for decentralized utilization excluding hydropower which is mostly centralized to grid systems and require distribution infrastructure.
