In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.
Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

Morocco is hosting an international exhibition on solar energy. The Solar Expo brings together companies from around the world to showcase their ideas for harnessing the sun's power. This is the Solar-E-Cycle. At the moment, it's just a prototype for a solar powered cycle. Canadian engineer Roger Christen and his Moroccan partners plan to improve their invention before it goes into manufacture. They want to make the Solar-E-Cycle available to people in Morocco and across Africa who have no access to electricity. "It's a three-in-one solution. It's mobility. You can travel 50 kilometres (31 miles) a day with this vehicle just with the sunlight that comes on the solar panel," says Christen "It's a power station on wheels, so you can light the home, operate the internet, the televisi...

Ice 2020 https://www.youtube.com/playlist?list=PLoUC9ERJ-zHDrzsyE9XV_yA49Pqvp9cXc It is 2020. Findings by environmental scientist Professor Thom Archer suggest that Halo, the corporate energy company drilling on the Greenland Glacier are causing it to melt. Archer's warnings are ignored, so he heads to the Arctic to find indisputable evidence. Upon arrival, he realizes humankind is under immediate threat, and races home to save his family. The glacier collapses, with devastating consequences. Astonishing weather patterns emerge and plunge the world's temperatures into steep decline.

The movie story deals with Ramachandran a genetic scientist who doesn't get due credit and funds for his research. He tries creating a human with several talents through baby designing, which thus leads to the birth of his sons, who are conjoined together above the waist. Since they share a common heart, doctors suggest a sacrificial surgery, to which their mother Sudha objects. They begin raising their children, Vimalan and Akhilan. In the following years, Ramachandran makes it big with the help of Sudha. His company, Locus Lacto Products, makes huge profit through their product "Energion", the top-selling children’s powdered milk energy drink in the market. Vimalan and Akhilan are poles apart in character, the former being decent and good at studies while the latter is care-free and poor...
