The market economy is an economy type in which the private sector controls all the businesses in the particular economy. The government doesn't have any influence on the production of goods and services. The production of goods is actually determined by the consumers, as they are the ones that buy the products, and they choose the products that have the highest quality with the lowest price, or rather a balance between the two.
Electricity is what powers our everyday lives! We use it to power lightbulbs so we can see at night, and it also powers streetlights so we can drive in the dark. Heck, without electricity we wouldn't have cars in the first place! The very computer you asked this question on wouldn't exist either!
Electricity made a whole new type of transportation able to be created! It also made instant communication with one another possible! The world as you know it today would not be possible without electricity, it does much more than I mentioned in this answer too!
