"On the eve of the Paris climate conference, a new analysis from Stanford University has laid out a roadmap for 139 countries to power their economies with solar, wind, and hydro energy by 2050.
The Stanford study focuses on what is has dubbed “WWS” – wind, water and sunlight. And it includes not just electricity but transportation, heating and cooling, industry, and agriculture, forestry and fishing.
It says the world can reach 80 per cent “WWS” by 2030, which puts the Greens target for 90 per cent renewable energy for electricity only for Australia by the same date in a different perspective." "The roadmap outlines numerous benefits – millions of jobs, no impact on economic growth – and total savings from fuel costs, environment and climate damage of nearly $US5,000 a year.
Stanford study estimates that it will save each person in the 139 countries an average of $170 a year on fuel costs, and $2,880 a year in air-pollution-damage cost and $US1,930/person/year in climate costs (2013 dollars).
They have even broken now the equipment and installations needed into each country. It appears eye watering, but Stanford says the land use requirements are minimal – just 0.29 per cent of the land area, mostly for solar PV, not including reclaimed fossil fuel plants."
