Tohirbekov and the solar cooker.

Spain is a very sunny country.

Solar power is environmentally friendly.

The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720 ) is a planetary nebula in the northern constellation of Lyra.

The solar cooker is not perfect, however.

Germany is not a sunny country.

Solar power is becoming increasingly cheaper.

The weather's warm and sunny today.

Coal, like solar energy, is widely available.

Right now, solar paybacks are between 30 and 50 years.

Solar energy is a new source of energy.

Solar energy does not threaten the environment.

The sunny side of the hill is full of deciduous trees.

And sunfish is one of the words for basking sharks.

Our solar system is always in motion.

In this infrared photo, the Helix Nebula looks back at the observer like a red eye.

I tried to figure out maybe solar's become attractive.

Solar energy is also finding its way into agriculture.

The room I've moved into recently gets plenty of sunshine.

The problem is that solar energy costs too much.

The problem is that solar energy is too expensive.

Solar power has become much more affordable in recent years.

Solar power has become much more affordable in recent years.

Solar output is nearly, but not quite, constant.

A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases.

The most promising technology in the long term is solar power.

The Solar Terrestrial Relations Observatory (STEREO) mission was launched in October 2006.

Charles Messier also noted it in 1764, but thought it a nebula without any stars associated with it.

The four brightest HII regions are designated NGC 588, NGC 592, NGC 595 and NGC 604.

It is a reflection nebula, caused by dust reflecting the blue light of the hot, young stars.

Solar can do it, and we certainly have to develop solar.

So here's our little solar system, as we pull away from our melted planet here.

Solar energy also plays an important role in rural businesses.

And, of course, on a cloudy day a solar cooker can be rendered impotent.

We are exploring new sources, such as solar and atomic energy.

That is the best in humanity, there that is who and what I love.

Solar radiation equals roughly 10,000 times our current energy use.

Solar energy is used to heat the water for the canteen, bathrooms, and gym showers.

The photograph published by the European Southern Observatory shows the Trifid Nebula in the Sagittarius constellation, several thousand light years away.

Not all these technologies are at the same level of maturity, however, and while they may be technically up to the mark, a number of conditions need to be met before they can be economically competitive the hydropower and geothermal energy can be competitive with coal and natural gas when the resource is easily accessible, of good quality and close to the consumer.

Our solar system is 26,000 light years from the center of the Galaxy.

The Sun in fact, our whole solar system orbits around the center of the Milky Way Galaxy.

Epidemiologic data from Australia, animal studies with artificial sources of ultraviolet light, and the development of skin cancer in individuals with a genetic inability to correct the DNA damage caused by ultraviolet radiation provided circumstantial evidence of the connection.

For over fifty years, ultraviolet radiation from the sun has been the number one suspected cause of skin cancer.

That's why the Solar Home System Project, launched in 2007, is particularly good news for Bangladesh.
