Solar power is considered to be a renewable power source in the sense that the sun will continue to shine for billions of years to come, which is such a long time that it might as well be forever as far as we personally are concerned. However, the sun does not really last forever, and when it eventually changes into a red giant, billions of years from now, it will not be renewable by any means that I can foresee (although, of course, if the human race continues to exist for billions of years, there is no telling what new technology will be developed, or what will be possible with that technology).
For all practical purposes (i.e., as pertains to us--homo sapiens), it IS renewable and is referenced as such; however, the sun won't last forever! It has been projected that the sun's lifespan is approximately 10 billion years--if I'm remembering correctly. It has already lived about 5 billion, and will live another 5 billion; although towards the end it will pass into other forms--red giant, white dwarf, etc. If you wanted to dwell on this technicality, then no, it's not renewable. But by then we will either be extinct or will have evolved into something else (hopefully a species that's much wiser) and probably will have left Earth for greener pastures. Also, because of entropy, nothing in the universe is renewable--technically; at least, in my humble opinion (although inflation theory and others may allow for the possibility of universes themselves being renewable indirectly--by continuously spawning new universes!)
Interesting question! The answer is, "No". Stars like our Sun generate light and heat through the nuclear fusion of hydrogen into helium in the core of the star. While our Sun has been shining for about 4.5 billion years and is expected to last for another 4 billion years, the Sun will eventually begin to run out of fuel, and start to collapse. When this happens, the pressure of the star's collapse will increase the interior temperature to the point that the helium in the Sun will itself begin to fuse, causing the Sun to expand into a red giant.
Because the Sun isn't big enough to undergo a supernova explosion which would recycle a substantial fraction of its mass back into space (to be used in the formation of new stars and planets), most of the mass of the Sun will be trapped by gravity and will, over the lifetime of the universe, continue to shrink and grow cooler. This may take a trillion years or more.
So, sunlight, while plentiful, is not a "renewable" resource. However, when sunlight hits the Earth, it can be stored in a number of different forms!
When sunlight hits water, the Sun evaporates the water from lakes, rivers and oceans. The water vapor forms clouds in the atmosphere. The clouds drop the evaporated water as rain, which falls back to Earth. Some of the rainwater runs down hills and into rivers, where we can capture the water and use the running water to power waterwheels and hydroelectric dams. So recycled sunlight is the ultimate source of hydroelectric power!
When the sunlight hits fields, this helps crops to grow. We eat the food from the crops, or cattle eat the plants and we eat the animals. So, our bodies use recycled sunlight for power!
Millions of years ago, the sunlight helped plants to grow, and over the course of millions of years, layers of decayed plant material (and the decayed bodies of the animals that ate the plants) settled into the Earth. Our "fossil" fuels such as coal and oil are now burned to release the stored sunlight energy.
So in a real sense, ALL energy is solar energy; simply converted from one form to another.
No, solar energy is a renewable energy source. It is derived from the sun and can be constantly replenished.
Solar panels provide renewable energy by converting sunlight into electricity. This helps reduce dependence on non-renewable energy sources and lowers carbon emissions, contributing to a cleaner and more sustainable environment.
Sunlight can be harnessed to provide energy, and the sun will be shining for billions of years to deliver that energy. Each sunrise signals energy renewal.
Solar power gets its energy from the Sun. Photovoltaic cells in solar panels convert sunlight into electricity by absorbing photons from the sunlight and creating an electric current. This renewable energy source is a clean and sustainable alternative to fossil fuels.
Solar energy is abundant because the sun continually emits vast amounts of energy, which can be harnessed through solar panels to generate electricity. It is renewable because sunlight is inexhaustible and available in abundance, making it a sustainable energy source for the long term without depletion.
Sunlight is a renewable resource. It can be harnessed using solar panels.
Sunlight is a renewable resource. It can be harnessed using solar panels.
Sunlight is renewable. Even if we use as much of it today as we can, it still comes back tomorrow just as much as today.
If it could be done it would be similar to renewable. (it is what the Sun does and Sunlight is looked at as renewable energy).
sunlight & wind
Renewable resources. These are natural resources that can be replenished over time, such as sunlight, wind, and water.
sunlight?
renewable primary energy
sunlight or wind
Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished).
Yes, the sugar is made from growing plants and the energy is therefore sunlight which, in growing plants is renewable.
Almost all renewable energy depend on sunlight somehow, so if the sun died out
