In https://github.com/quintel/etmodel/issues/1870, a list of technologies that may be interesting to have such a slider for is given.\r\n\r\n# Simplifying circumstances\r\n\r\nMany power plants in the ETM actually with the same type of process and their efficiencies can therefore be updated by a single slider. \r\n\r\n# Complicating circumstances\r\n\r\n* Volatiles (wind, solar, hydro) are not demand driven. Changing their efficiencies naively will result in less 'wind', 'sun' and 'hydro' used. This is not what a typical user would expect which is that an improvement in efficiency results in a higher output capacity. In other words, changing the efficiency of, for example, a solar panel, the same surface area of solar PV leads to more electricity.\r\n\r\n* Changing the efficiency of a power plant makes it cheaper (if you keep the output fixed). With less steel, concrete and fuel, you can make the same amount of electricity. This means that the cost sliders that we have for the same plants will become (partially) redundant. Making the plant more efficient will reduce its investment cost, fuel cost, O&M cost but also its CO2 but the sliders for cost just update one of these each. So, we have an entanglement of sliders which might confuse some users. \r\n\r\n# Interface \r\n\r\nBecause of the last point, the cost section of the ETM might be the most logical place for the efficiency sliders.\r\n\r\n# Comments \r\n\r\nBecause of the impact on the usability and transparency of the ETM, I will invite you to have a meeting about this soon."},"comment":{"url":"https://api.github.com/repos/quintel/etmodel/issues/comments/136693552","html_url":"https://github.com/quintel/etmodel/issues/1893#issuecomment-136693552","issue_url":"https://api.github.com/repos/quintel/etmodel/issues/1893","id":136693552,"user":{"login":"ChaelKruip","id":1303760,"avatar_url":"https://avatars.githubusercontent.com/u/1303760?v=3","gravatar_id":"","url":"https://api.github.com/users/ChaelKruip","html_url":"https://github.com/ChaelKruip","followers_url":"https://api.github.com/users/ChaelKruip/followers","following_url":"https://api.github.com/users/ChaelKruip/following{/other_user}","gists_url":"https://api.github.com/users/ChaelKruip/gists{/gist_id}","starred_url":"https://api.github.com/users/ChaelKruip/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ChaelKruip/subscriptions","organizations_url":"https://api.github.com/users/ChaelKruip/orgs","repos_url":"https://api.github.com/users/ChaelKruip/repos","events_url":"https://api.github.com/users/ChaelKruip/events{/privacy}","received_events_url":"https://api.github.com/users/ChaelKruip/received_events","type":"User","site_admin":false},"created_at":"2015-09-01T12:19:20Z","updated_at":"2015-09-01T12:19:20Z","body":"Including @dennisschoenmakers @AlexanderWirtz @jorisberkhout "}}
