Listening to radio and TV interviews of supermarket operators, I realized that these people are hard hit by the successive increases in the price of electricity. It turns out that a medium sized grocery store easily spends P1 million/month on electrical bills alone. If I may make my humble suggestion, they should produce their own electricity by operating their own generators that can be powered by a combination of solar and wind power. Most of the groceries and malls occupy a lot of space and have huge roofs that can be used for renewable power generation. They may also use alternative fuels in running their mini power plants.
