Power tools and heavy machinery is a pretty big issue for building because they are so important for how we build in this day and age. In rural areas using them becomes a bigger issue because of less access to the national grid and the logistical problems with getting enough diesel and petrol to the site for when it is needed. These problems are solved through a variety of means but the truly essential one is by stockpiling large amounts of fuel.
If you visit a building site you’ll usually see massive generators which are used to convert fuel into electricity. This powers everything from break-rooms for the workers to certain power tools which rely upon an electrical supply. They are accompanied by massive fuel containers which contain thousands of gallons of fuel, ensuring a constant supply of available fuel for everyone and every machine on site.
