Make a Wish: Climate Change or Energy Poverty

Mats van Kleef's picture

Make a WishIf you could have just one wish, would you choose to solve climate change or energy poverty?

Resolving these two calamities is fundamental to the wellbeing of the planet and people. Climate change is caused mainly by the consumption of energy and the associated greenhouse gas emissions. Energy poverty is the lack of access to modern energy services. Helping 1.3 billion people access electricity and 2.6 billion people to have clean cooking facilities will greatly increase the world’s energy consumption and resulting GHG emissions. Spending money to mitigate climate change uses valuable resources that could more directly benefit the poor who have so little energy and such unhealthy cooking facilities. How do we address both energy poverty and climate change? This is as much an ethical dilemma as a technological challenge.

Urban Careers and the Twenty-Ninth Day

Lily pads on lakeA helpful way for young math students to grasp the concept of exponential growth is to look at water lilies growing on a pond. They grow exponentially and double in area each day. If they will fully cover the pond by the 30th day, on what day is the lake half covered? The twenty-ninth day[1].
 
This year I had the honor of teaching 4th year energy systems students who will graduate later this month (their blogs on energy issues will be presented on this site over the summer). These graduates are particularly essential. During their careers they will be part of the world’s largest ever city-building spree. Their task will be to again double the world’s cities.
