This page contains published fact-based articles that aims at shedding light on relevant aspects of our energy sources - both positive and negative. The goal is a constructive debate that is based on the recognition that we have a climate challenge that we have to do something about, and where we seek to solve this challenge by relating to the totality.
The articles are written by, or with, Jonny Hesthammer, former geology and geophysics professor and currently CEO of M Vest Energy. Not everyone will agree with everything that is written, but the content will hopefully form the basis for reflection and factual discussion - and where there is agreement on the ultimate goal: zero emissions with the least possible negative impact for the planet and human beings.
Please note that numbers for "cost" and "not in operation" (an indication of stability) has been updated on the calculator and footprint page with the latest information available. However, the articles and associated figures still reflect 2018 numbers.
Fossil energy dominates the world's energy consumption but has the highest CO2 emissions and death rates. Nuclear and renewables are the safest energy sources with the lowest emissions but covers only a small share of global energy consumption.
Of all low carbon sources, nuclear has the lowest spatial and material requirements. Renewable energy has much lower power densities than other non-renewable sources. Solar and wind power also have the highest consumption of critical metals.
Solar and wind power are steadily declining in price, and wind power already delivers cheaper electricity than coal and nuclear power – if stability is not a requirement. If the need for backup is added to the total costs, both fossil and nuclear …
All energy sources affect health, environment, climate, and economy to different extents. These are important factors that must be considered when assessing the energy mix of the future. Renewables have clear challenges that are best solved in …
The climate debate is characterized by many strong opinions, of which far from all are fact based. It is possible to become carbon neutral, but wishful thinking is not enough.
