Air conditioning: energy demand sensitivity?
This data-file quantifies air conditioning energy demand. In the US each 100 variation in CDDs adds 26 TWH of electricity (0.6%) demand and 200bcf of gas (0.6%). Air conditioning already consumes 7% of all global electricity and could treble by 2050.

Air conditioning: energy consumption?
The average US home uses 2,000 kWh of electricity for air conditioners each year. Air conditioning energy consumption is broken down from first principles in this data-file, as a function of temperatures, humidity, heating days, household size, insulation and coefficient of performance (COP). What routes to lower the air conditioning energy demand and CO2 emissions?

Cryogenic air separation: costs and energy economics?
This data-file calculates the costs of cryogenic air separation units, which are important in the production of industrial gases, ammonia, metals, materials, medical applications and new energy technologies such as blue hydrogen. Good base cases are $100/ton oxygen, $20/ton nitrogen, $200/Tpa capex and 60kWh/ton of electricity (on an input air basis).

Windy physics: how is power of a wind turbine calculated?
This data-file is an overview of wind power physics. Specifically, how is the power of a wind turbine calculated, in MW, as a function of wind speed, blade length, blade number, rotational speed (in RPM) and other efficiency factors (lambda). A large, modern offshore wind turbine will have 100m blades and surpass 10MW power outputs.

Cryogenic air separation: company screen?
Over $100bn pa of industrial gases and $5-6bn pa of cryogenic air separation plants are produced each year. This data-file is a screen of leading industrial gas companies and cryogenic air separation companies, breaking down their market share (number of ASUs constructed) history, geography, sales and headcounts.

Compressed air energy storage: costs and economics?
Our base case estimates for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year. Our numbers are based on top-down project data and bottom up calculations, both for CAES capex (in $/kW) and…

Building automation: energy savings, KNX case studies and companies?
High-quality building automation typically saves 30-40% of the energy needed for lighting, heating and cooling a building. This matters amidst energy shortages, and reduces payback times on $100-500k up-front capex. This data-file aggregates case studies of KNX energy savings, and screens 70 companies, from Capital Goods giants to private pure-plays.

Energy Recovery Inc: pressure exchanger technology?
Pressure exchangers transfer energy from a high-pressure fluid stream to a low-pressure fluid stream, and can save up to 60% input energy. Energy Recovery Inc is a leading provider of pressure exchangers, especially for the desalination industry, and increasingly for refrigeration, air conditioners, heat pump and industrial applications. Our technology review finds a moat.
