As of today, you can find the book Duurzaam Varen in the bookstores and online. Sorry, it is in Dutch, so here it is described in English
The book covers a about all actions you can take to prevent and reduce fossil fuel emissions, from diesel, gas and petrol. Every chapter starts with the small things you can do right now. Like tricks to reduce the use of your diesel engine, or your devices in your galley. Step by step it builts up to a complete sailing and living in fossil freedom.
There is also an eye for other aspects, such as the use of water, and how to stop your water pollution. Think of the e.coli bacterias we emit in the water. Think of the ecocides we use in our bottom paints and are spread in our ambient water. With some changes this is unnecessary.
Everything is systematically built up, starting with the question what you can prevent. Prevention is mostly the cheapest. Since the best energy is the energy you don’t use, or not? Second is if one can reduce, then reuse/repair, or if not, recycle. When these options are covered, you use about 70 to 80 % less. The remaining 20-30% of the energy can be taken care of by solar panels, wind and propeller alternators.
