About

Energy security is a key element in building a well developed and strong Nation. Despite petroleum products are very expensive, they are running out of us. Renewable energy sources are the only bridge to cross over the energy crisis. That's why we believe alternative energy can build an energy sustained world.

There are several renewable energy sources, for example, solar power, wind power, ocean energy, etc, but they are inefficient, expensive, and intermittent. New technologies need to be developed in order to avoid these limitations.

There are several ongoing pieces of research to make renewable energy more efficient, less expensive, and less intermittent. Energy-physics.com tracks each and every development in the energy world to provide our readers a fresh and clear content. It is our vision to keep everyone updated with the latest energy technologies and developments.

"In the race to develop technologies to slow climate change, the world is off track."

Deployment of renewable energy is progressing, but not fast enough. Nuclear power is behind the curve. Key technologies like carbon capture and storage, which the Intergovernmental Panel on Climate Change has deemed critical to staying within the target, are still in their infancy.

Consider the sun. The world has made huge leaps in solar technology. The price of solar panels has fallen sharply — in substantial part because of significant Chinese investment in panel manufacturing. Smart grid technologies have enabled owners of solar homes to buy power from the grid when the sun is down and sell it back when it is shining, and new business models have encouraged a boom in residential solar installations. In some parts of the country, solar energy has become competitive with conventional power from fossil sources.

To provide a big share of the world’s energy, the M.I.T. researchers wrote, solar power must overcome three big obstacles: It is still more expensive than fossil fuels; it is tiny relative to the scale it will need to play a major role in the global energy system, and it is intermittent. And turning to the sun for a big chunk of power requires a leap in the basic technology converting photons into electric power to sharply reduce the price. The silicon-based solar panels that produce most solar energy today won’t cut it.

“I’m an environmentalist. I’m doing this because I think nuclear power is the best way of producing large amounts of carbon-free electricity,” says Dewan, an MIT nuclear engineer, and National Geographic emerging explorer. She says the world needs nuclear—along with solar, wind, hydro, and geothermal—to cut heat-trapping emissions.

Not all environmentalists agree. In fact, nuclear power divides its ranks. Its radioactive waste and accidents—including the United States’ Three Mile Island in 1979, Ukraine’s Chernobyl in 1986 and Japan’s Fukushima Daiichi in 2011—have prompted many to argue nuclear is just too dangerous. Japan and Germany are paring back.

Yet many climate scientists say nuclear has to be part of the solution. Citing the dangers of global warming, they say there’s no realistic path forward without a “substantial role” for nuclear. Their public appeal calls for “a fresh approach to nuclear power in the 21st century.” The next-gen designs are not your grandfather’s reactor. They promise to be safer, cheaper, and more efficient.
