Before agriculture we were hunter/gatherers.
It wasn't, really...There were rivers, streams and ponds just like today and most early settlements were puposedly near to natural sources of water. If we are talking about finding underground, hidden sources of water the answer would be that early humans had only very primitive tools to get at those sources.
In ancient Greek mythology, the gods were believed to be taller than humans, with some sources describing them as being around 12 to 15 feet tall.
Gold has been known and used by humans for thousands of years, with evidence of gold artifacts dating back to around 4000 BC in ancient civilizations such as those in Egypt and Mesopotamia. The discovery of gold in its natural state likely occurred even earlier, as humans have been drawn to its shiny appearance and malleability. Thus, gold has been known to humanity for approximately 6,000 years.
hades was greatly feared by humans and was never in contact with humans for, he never left the underworld.
The first renewable energy source used by humans was likely wood, as it was used for heating and cooking thousands of years ago.
Humans need more electricity, regardless of source. Hydroelectric and other renewable sources of energy are preferred to energy produced from the burning of fossil fuels.
Renewable energy sources such as solar, wind, and hydropower are considered to be inexhaustible as they are naturally replenished. These sources of energy do not deplete over time and can be utilized indefinitely without running out.
Yes
Relying heavily on non-renewable sources of energy leads to environmental degradation, resource depletion, and contributes to climate change. Transitioning to renewable sources of energy like solar, wind, and hydro power is crucial for a sustainable future. Reducing dependence on non-renewables will help preserve the environment and ensure a stable energy supply for future generations.
Humans mostly use electrical energy generated from various sources such as fossil fuels (coal, oil, natural gas), nuclear power, and renewable sources (solar, wind, hydropower). This energy is used for lighting, heating, transportation, and powering electronic devices.
A resource that humans use to produce energy is called a fuel. This can include sources like coal, natural gas, oil, or renewable resources like solar, wind, and hydro power.
It is energy that won't last forever, or that will run out. An example of this is petroleum, which does form naturally, but only over thousands of years. At the rate at which humans use it, petroleum will most certainly run out before natural processes can replenish it.
Electricity itself cannot be considered renewable or nonrenewable--what matters is how that electricity is produced. Any resource that can be replenished by sustainable processes at a rate faster or equal to its use by humans can be considered renewable. Most of the electricity in the world is generated from nonrenewable fuel sources, such as coal, gasoline, natural gas, or other fossil fuels. Sources such as solar cells, windmills, hydroelectric dams, and geothermal power plants are considered renewable sources of electricity. Alcohol and biodiesel derived from renewable crops such as corn, sugarcane, and switch grass are also renewable sources of energy. Nuclear power plants, especially breeder-style reactors, may also be considered renewable sources of energy.
Humans as a society primarily use fossil fuels as the main source of energy, such as oil, coal, and natural gas. These energy sources are used for electricity generation, transportation, and heating, among other applications. However, there is a growing shift towards renewable energy sources like solar, wind, and hydropower to reduce reliance on fossil fuels.
A sustainable resource means it will last for ever, or for as long as humans renew the source.
The three main energy sources of the earth are fossil fuels (such as coal, oil, and natural gas), renewable energy (such as solar, wind, and hydropower), and nuclear energy. These sources provide the majority of energy used for electricity generation and transportation worldwide.
