Ok some people like drones and some people would even like to bring portable generators to the landing area. Meaning they can squeeze a few more flights and the cost of generating power from fossil fuels...
In the past when people mention it, but I cringe a bit as a 45 percent efficient diesel engine is powering a switch-mode power supply with reasonable efficiency convert down to DC voltages and reduced further in the battery management system... With unknown factors of the energy to refine the Diesel and the cost and transport of the fuel or your car and equipment... I find the whole aspect of energy into transport a little discomforting...
But can you go completely green with your drone...? Set aside the Shipping of your drone from china or your own transport of your car... There might be methods that you can use renewables via the charging process or at least something to strive for...Its fair to say I am advocate for renewable energy, for which I started as a way to save money and carried on reading the arguments for renewals both financial and environmental...
The first method is to charge with your house solar panels... its likely that most people don't have solar panels and the majority of the public might not benefit the same way as solar home owners do... Or there maybe a few people experimenting on portable solar energy via their mobile holiday homes or camping power equipment...rigging out the solar panels for transport can be a reward in itself... As Glamour camping or Gl-amping may include activities such as droning flying in the spoilt for gadgets world of a modern day camper... Has hiking goes hand in hand with some people, so why not bring a portable drone to some far off location and do a flying sefie...
For the droner with a electric car its much more likely you do have solar panels and that your car it self, can charge your drone via its 12v outlet... (as well as most other cars) From my car there is a 12v lead acid battery with I presume powers the console and possibly the headlights... Dji have charging units that can use 12v car outlets, which seem to me the best way to transfer DC to dc or the car battery to the Drone battery...While other people sort out a DC inverter then their regular DJI charger, which defeat the object as energy is lost due to the conversion of DC to AC power and then back to DC for the Aircraft battery itself... But its understandable if someone who cant be arsed to buy a 12volt charger...
For the rest of the public its simple a matter of waiting for a sunny day and charge... Certain countries like Germany or Iceland, Sweden, Costa Rica even the United kingdom have improving renewable energy sources... On sunny days in the spring or summer you will see some reports would say 100% renewables powering the country... Its a growing pheromone that people are starting to get on board with...
But most countries agreed to the plan of Banning petrol and diesel by 2040... While France, has a plan to cut coal power by 2022..
Besides the fact that every sensible country making plans for the future, I have to conclude that the energy made now is getting cleaner... Either way your drone could be powered conveniently by fossil fuel generator or my a renewable source , the results are the same... Flying for a fun afternoon... Its up to the mad few of us that would lead the way to clean drone fights, by buying solar panels and portable batteries...
For me its not about being green or trying to do my bit for the planet... Its more of a engineering challenge that I can use of the shelf items and arrange a power source I can take with me to have a fun afternoon... The results are the same and I get a back up power system in case of Blackouts (which happens from time to time)... Or simply buy more aircraft batteries, charge from your home and fly longer...
