Improving Wave Energy
Ocean energy is still one of the biggest untapped clean energy sources on the planet. There are many studies that have shown that it could provide power for millions of homes in the U.S. alone. But despite this, the technology is still in its infancy and it is unclear when and if it can become a major contributor to our energy needs.
A Giant Solar Power Plant In India
In late September, the world’s largest solar power plant went online in the Indian state of Tamil Nadu. It is a 648 MW array of solar panels that is spread across 2,500 acres in the town of Kamuthi and will supply enough energy to power 300,000 homes.
The Economics Of Renewable Energy
Very few people are against the use of renewable energy sources like solar and wind power in principle. It is hard to argue against generating power from resources that are free and plentiful. The main knock against renewable power sources has been that they cost too much compared with conventional, fossil-fuel technologies.
Wave Energy In The United States
By some estimates, America’s oceans could provide enough electric power to meet a quarter of the country’s energy needs. Despite this, until recently the contribution to the U.S. electric grid from marine energy has been exactly zero.
Offshore Wind At Last
Europe has embraced offshore wind power as a major contributor to its electricity needs for a long time. As of June, there was a total of 3,344 offshore wind turbines with a combined capacity of over 11.5 gigawatts of power connected in European waters in 82 wind farms located in 11 different countries and providing power to millions of people.
Virtual Power Plants
The traditional model of the electricity grid is one where centralized large power plants send power through transmission lines to substations and then on to homes and businesses. As localized renewable energy sources, energy storage systems, and efficiency systems proliferate throughout the system, a new concept is emerging: that of the virtual power plant.
Energy Intensity
Every stage of civilization is characterized by its use of energy. From burning wood to steam engines to our electrified society, energy is behind everything we do. Over time, human society has become increasingly energy intensive. As our standards of living have improved and as we overcome the effects of weather – either cold or warm – it takes more and more energy to live the lives we lead.
Solar Power 24/7
The biggest challenge facing both solar and wind power sources is that they don’t produce power around the clock; they only work when the sun is shining or the wind is blowing. As a result, they don’t quite measure up to the requirement for power on demand.
