the sun
Gravitational energy is generally considered a nonrenewable source because it is derived from the position and mass of objects in a gravitational field (such as Earth's gravity). Once this energy is used, it cannot be easily replenished on a human timescale.
Non-renewable energy sources are those that drain the fossil reserves. The most important non-renewable energy source on Earth is coal. If something is not done to make the switch to clean or green energy, the coal supply is not expected to last for more than 40 to 50 years.
The Earth is our home planet, located in the solar system and the third planet from the Sun. Earth is known for its diverse ecosystems, abundant water supply, and capacity to support life. The most important nonrenewable energy source is fossil fuels, including coal, oil, and natural gas. These fuels formed over millions of years from the remains of ancient plants and animals, but their extraction and use contribute to environmental issues such as climate change.
the sun
energy source for all life on earth
Geothermal energy is considered a renewable energy source because it harnesses heat from the Earth's core, which is continuously generated by radioactive decay and is virtually inexhaustible on human timescales.
The sun is the main source of energy on earth.
The primary is the sun
Geothermal energy is considered a renewable energy source because it relies on heat from the Earth's core, which is continuously produced. This heat can be harnessed to generate electricity and heat buildings without depleting the resource.
It provides basic energy source and life on Earth
sun is the energy source . We know that the primary produsers are plants, the source of photosynthesis is sun . Photosynthesis is giving food and energy to do all activities. Because sun is very very important to our planet earth.
because plants need it for energy and we eat plants. plants are basic energy source we need the energy when it's transferred from one source to another
