Humans can't live without energy - they have always used energy.
using their senses
Long before "we" were humans, when our early prehuman ancestors ate a piece of fruit. Also when they felt the sun warm them in the morning.
Electricity by converting it using wind turbines.
Humans use food for energy.
They modify the habitat (using fossil energy usually) to suit their requirements.
A solar panel collects energy from sunlight, just like windmills convert wind energy. The mechanics inside the solar panel and inside the building let humans use solar energy. There is no more harm to humans from solar energy than there is from using energy produced from the wind.
The sun is the most abundant energy source that can be harnessed by humans. Solar energy is renewable, clean, and can be captured using various technologies like solar panels to generate electricity for homes and businesses.
That sounds as if you want to stop using energy. That's not possible - we need energy to survive. We (humans) can reduce our use of energy, and we can try to reduce the environmental impact of the energy we do use.
they break sugar down using enzymes which are proteins, into energy, oxygen is used as an energy supplier to the reaction which creates water and Co2
As we do not have endless supply of the traditional fuels, of course we have to research on alternative ones. Using the energy of sun or using bio-energy can be the future.
Solar energy is the most abundant energy source capable of being harnessed by humans. The sun emits an incredible amount of energy that can be converted into electricity using solar panels. Utilizing solar power is a sustainable and renewable energy solution for a cleaner future.
The prehistoric era was before humans.
