Unlike Wind and Solar energy which fluctuates wildly throughout the day, there is another renewable form of energy that is much more predictable. I’m talking about Tidal Energy, and it’s reported to have enough potential energy to power the whole world. So why doesn’t it? What new breakthroughs in tidal energy can finally bring tidal energy to the same level of investment and success as wind and solar? Is Tidal energy finally ready to make waves? If Tidal Energy Can Power the World – Why Doesn’t It?

Harnessing sunlight to meet the ever increasing demand for energy at the global scale has long been pursued by scientists and engineers.

During his talk, Dr. Conings will discuss the relevance of solar energy, an everlasting sustainable energy source, that can reduce the dependency on adverse carbon emitting energy resources. Getting at the physical chemistry of burgeoning metal halide perovskites, his talk will focus more deeply on the groundbreaking photovoltaic applications of this state-of-the-art material class, shedding light on their ability to drastically improve global solar energy harvesting.

Harnessing sunlight to meet the ever increasing demand for energy at the global scale has long been pursued by scientists and engineers. Materials scientist Dr Bert Conings, from the Institute for Materials Research (IMO-IMOMEC) at Hasselt University, is among researchers on the vanguard pushing technological boundaries to increase the efficiency of solar energy production. During his talk entitled “A “Eureka” for Solar Energy”, Dr. Conings will discuss the relevance of solar energy, an everlasting sustainable energy source, that can reduce the dependency on adverse carbon emitting energy resources. Getting at the physical chemistry of burgeoning metal halide perovskites, his talk will focus more deeply on the groundbreaking photovoltaic applications of this state-of-the-art material class, shedding light on their ability to drastically improve global solar energy harvesting.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Explore the sustainability of fossil fuels, nuclear power, and renewable energy and how much space each of these power sources use.

No matter how we make electricity, it takes up space. Coal requires mines, and plants to convert it into electricity. Nuclear power takes uranium mines, facilities to refine it, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels. So how much space would it take to power the whole world? Explore the sustainability of different power sources.

Biomass: How clean is energy from waste and plants really?

Alternative Energy No Comments »

Clean energy from re-growing resources and waste. Biomass sounds like a perfect alternative power source. Globally, at least 5% of energy come from biomass. But what does it mean if we use organic matter for fuel or electricity?

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

Is tidal power a reliable form of clean energy?

Alternative Energy No Comments »

ABC’s Maggie Rulli visits the Orkney Islands to explore a new technology and whether it could change how we generate power.
Video Rating: / 5

Tidal flows provide a consistent source of kinetic energy as a result of the interaction between the gravitational forces of the Earth-Moon-Sun system. Tidal energy technologies have the advantage of being highly predictable and dependable power output to the electricity grid. Delft University of Technology conducts research to develop innovative solutions for Tidal Energy. For more information, please visit: http://oceanenergy.tudelft.nl/tidalcurrent-energy/

Spain's solar energy crisis: 62,000 people bankrupt after investing in solar panels • FRANCE 24

Energy Efficiency No Comments »

Seventeen years ago, Spain’s socialist government decided to inject subsidies into renewable energy. As a result, thousands of Spanish families massively invested in photovoltaic energy. But, as you’ll see in our report, the dream rapidly turned into a nightmare.

Passive solar energy systems absorb heat directly from the sun without the use of mechanical and electric equipment, and energy cannot be collected or stored. Active solar energy systems use solar energy to heat a liquid through mechanical and electric equipment to collect and store the energy captured from the sun. Photovoltaic solar cells capture light energy from the sun and transform it directly into electrical energy. Their use is limited by the availability of sunlight.

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

Geothermal Energy

Alternative Energy No Comments »

In this animated whiteboard animations tutorial, I will teach you about geothermal energy and how does geothermal power plant work.

Q: What is geothermal energy?
Ans: The heat energy extracted from inside the earth in the form of water and steam is known as geothermal energy or geothermal power.
The earth’s core contain hot magma in molten or semi molten form. When the underground water comes in contact with these hot rocks, they burst up into hot springs and steam. We can then convert this heat energy into other forms of energy like electrical energy, etc.

All About Wind Energy

Alternative Energy No Comments »

#energy #wind #turbines #energy #ngscience
Electricity is very important to people. We use it to power our homes, cities and trains and cars.

One of the main ways we produce electricity is with the use of a generator. A generator is a device that converts mechanical kinetic energy into electrical energy.

A wind turbine is a very large windmill that uses the kinetic energy in wind to spin its blades. The blades spin a generator that transforms the energy into electrical energy.

Often, particularly in very windy places, many wind turbines are grouped together to form a wind farm. Wind farms can produce enough electricity to power whole cities.

A big advantage of wind energy is that it is a clean and renewable energy source. It does not require the burning of fuels and does not produce harmful emissions in to the air.

There are some disadvantages of using wind energy. The large spinning blades on a wind turbine can kill or harm flying animal like birds and bat. They can produce loud sounds that can disturb natural environments and be annoying to people. And if damaged, wind turbines can be expensive to repair.

Check out our related videos on the advantages and disadvantages of other electricity production methods.
