Energy economics: an overview?
This data-file provides an overview of energy economics, across 175 different economic models constructed by Thunder Said Energy, in order to put numbers in context. This helps to compare marginal costs, capex costs, energy intensity, interest rate sensitivity, and other key parameters that matter in the energy transition.

Carbon leakage: China versus the West, 1999-2019
The purpose of this data-file is to assess how ‘industrial activity’ has changed, in China and in the West (US and Europe), from 1999-2019, as a proxy for ‘carbon leakage’. We find heavier industrial activity is down 12% in the West over this 20-year period, and up 6.5x in China.

Vehicle mass: what opportunities to improve fuel economy?
Steel comprises c50% of the volume and c80% of the weight of materials in a vehicle. Each 1% reduction in mass yields a 1% improvement in fuel econome. Carbon fiber repays its extra costs after 30-70k miles, while hybridisation repays its extra costs after 10-30k miles.

Electrochemistry: battery voltage and the Nernst Equation?
What determines the Voltage of an electrochemical cell, such as a lithium ion battery, redox flow battery, a hydrogen fuel cell, an electrolyser or an electrowinning plant? This note explains electrochemical voltages, from first principles, starting with Standard Potentials and the Nernst Equation.

High voltage transmission cables: power parameters?
This data-file aggregates technical parameters of ultra high-voltage power lines. The average one transmits 6.5GW, at 800-1,000kV and 4,000 Amps, over a distance of 1,500 km. Every 500 meters, there is a 70m tall tower. The power lines have total mass of 200 tons/km, 2-3% losses per 1,000km and c$3M/mile costs.

Solar: energy payback and embedded energy?
What is the energy payback and embedded energy of solar? We have aggregated the consumption of 10 different materials (in kg/kW) and around 10 other energy-consuming line-items (in kWh/kW). Our base case estimate is 2.5 MWH/kWe of solar and an energy payback of 1.5-years. Numbers and sensitivities can be stress-tested in the data-file.
