The nuclear fission on the sun is the main source for solar energy. This radiation strikes the earth where it is captured by photovoltaic (PV) panels, or focussed on a Solar Tower. Both methods produce electricity, which is clean and renewable.
Because is essentially an endless supply of energy, with only a small percent of the actually total that even reaches the earth. Cosmically speaking the sun will be around for a few more billion years, more than enough time for man to have either moved on or messed the planet up beyond redemption. :) Newer and cheaper technologies are being developed all the time which increase the amount of "raw" sunlight that is converted into electrical energy. +++ Long enough in fact for Man to have died out as a species - individual mammal species appear to last about 3M years on average. So yes, we're OK, the Sun will still be in its present, stable stage. More seriously, whilst the engineering (I don't use that lazy word "technology") is improving all the time as you say, the difficulty will be the eventual expiry of the world's reserves of raw materials and fuels necessary for their manufacture, transport etc.
It can.You can have solar panels on your roof and store the energy in batteries.Concentrated Solar Farms focus thousands of mirrors on a central tower where a substance (melted salt, or water). Molten salt can store heat overnight, so electricity can be generated 24 hours a day.Other ways of storing solar power is to use spare electricity produced during the day to pump water to a uphill dam. This can then be released during the night to produce electricity.You can even charge the battery in an electric car (at night, when electricity is cheaper) and then run it into your home during the day.
I am pretty sure that it is gravitational potential energy.
The excess thermal energy is used to heat a coolant. You know those tall cooling towers that are the hallmark of a nuclear reactor? The final cooling is often done by spraying the hot water onto the concrete tower.
there are two types solar updraft towers solar power towers in updraft towers solar thermal collector are used in solar power towers heliostat are used
A solar updraft tower is just a very tall chimney set to capture hot air rising from a covered area. The sun heats the air and it all rises up the tower, spinning electricity turbines set at the foot of the tower.A solar tower (concentrated solar) is a container of water or other liquid (salt is often used) which is heated by a heliostat of mirrors on the ground. An array of mirrors focus the sun's rays on the top of the tower where the heated liquid is then used to generate electricity, often through steam turbines.
An updraft tower is the place in a Cumulus cloud in which an updraft goes up at a constant rate, until the dissipation process occurs or either the entire cloud, or just a part of a cloud itself.
they have a huge tower where big solar panels reflect sunlight into the tower and the tower makes that sunlight into energy to almost 500,000 homes

Yes, Tonopah Solar Energy, LLC is an affiliate of SolarReserve, LLC, and is the project company that is constructing the Crescent Dunes Solar Energy Plant, located near Tonopah, Nevada. Construction broke ground in August of 2011, with the solar power tower completed in January 2012.
Solar Observatory Tower Meudon was created in 1964.
There's two ways, I know one; the solar panels reflect sunlight to the top of a tower, the heat boils water to make steam and the steam spins a turbine to create energy.
Geothermal energy and Solar energy are two different things. Geothermal energy is thermal energy from the core of the planet while Solar energy is the radiation energy from the Sun. I believe the question would imply Solar Thermal utilization on Mars. On Mars, Solar energy is a lot lesser than earth. The radiation on Earth is at 1400 W/m2 while on Mars is only 600 W/m2. Solar energy can be harvest using Solar cell at 40% of what we would harvest on earth. In the case of Solar Thermal, Despite lowered black body temperature, Green house gases is absented on Mars and the surface temperature is a lot colder than earth. A solar thermal plant could effectively harvest at 60% efficiency as it is on earth. The very difference on Mars Solar Thermal and Earth version would be that Mars had little water, it could not use cooling tower in the same manner as on earth. The Heat rejection onto atmosphere would require large radiator in place of cooling tower. Reflects is necessary to enhance thermal efficiency since the solar density is lowered there.
Concentrated Solar Towers can be built to harness solar energy. Banks of mirrors focus the sun on a tower where molten salts heat up to over 300 degrees Celsius. This creates steam to generate electricity. The salts remain enough heat to work all through the night.
An intensive amount of solar energy would be needed to install a tower. For example that found in Arizona. While there are regions in US known for its sunlight the rays are as abundant to feed the receiver that feeds complete large structure source.
“Casa Solare” or Solar House has the smallest tower.
