Limits of reserves and resources<br />
• Availability and exploitability of resources, W (non-renewable)<br />
• Strength of fluxes, F, and efficiency ηηηη of use (renewable)<br />
• Tolerability of environment conditions (waste heat)<br />

1) Reserves, Resources W [J] are exhaustible<br />
coal, oil, gas, uranium, earth rotation (tidal power)<br />
2) Fluxes F [J/a] are renewable, but finite<br />
geothermal, solar (hydro-, wind-, wave-, biopower, photovoltaic,<br />
sun collectors, etc.) – Efficiency always ηηηη < 1, mostly
