Ocean energy facts

Ocean energy is a form of renewable energy that uses the ocean's tides, waves, winds, currents and thermal elements to generate energy.Oceans cover over 70% of the Earth’s surface, making them the world’s largest solar energy collectors. The oceans constitute the largest powerhouse on Earth.There are three basic ways to tap the ocean for its energy. We can use the ocean's waves (Ocean Wave Power)

Mozambique keen to use hydropower

Mozambique is keen to use hydropower for satisfying the country's energy needs. Therefore Mozambique will finally take control of the biggest dam in sub-Saharan Africa, Cahora Bassa, which is second biggest dam in Africa (just behind Egypt's Aswan dam), that was in Portugal's hands more than 30 years after Portugal's colonial power ended.President of Mozambique Armando Guebuza said: "We are

Biokerosene to be used in aviation

Biokerosene and biodiesel are both biofuels, both refined from oleaginous crops. At first it looked like the biodiesel will be the most significant of all alternative fuels and first one to find its place on the international market. But apparently it looks like that won't be the case because biokerosene looks to be adapting more quickly because of its potential use in aviation. As we all know

Fossil fuels - dominant but dangerous

Carbon cycle process. Click on picture for full size.Fossil fuels are non-renewable energy sources since they need millions of years to form and its reserves are being depleted much faster than new ones are being formed. Fossil fuels category includes oil, coal and natural gas. Fossil fuels when burning release carbon dioxide into the atmosphere and carbon dioxide is very harmful greenhouse gas,

Carbon capture technology - Best solution?

Carbon capture technology is technology that tends to reduce negative impact of global warming by capturing carbon dioxide(CO2) from power plants and subsequently storing it instead of releasing it into the atmosphere. Capturing carbon dioxide means nothing without its storage and the storage of carbon dioxide is still relatively unknown in majority of the world countries.Carbon capture

ITER project - The only real problem is time

ITER is joint international research/engineering project that has its goal to provide future electricity from fusion power. Fusion reaction releases energy when two light atomic nuclei fuse together forming heavier nucleus and this released energy could well be main future energy source. ITER's main goal is to harness nuclear fusion as the future energy source and if all goes well this project

Geothermal energy - Use and working principle

Geothermal energy is energy that is gained thanks to an intensive heat that continuously flows outward from deep within the Earth. Word “geothermal” has its roots in two Greek words, “gheo” which means Earth and “thermal” which means heat. This energy is mainly generated from Earth's core since temperature of Earth's center is reaching temperatures above 6000 degrees Celsius which is even hot

Wind power revolution - Connecting wind farms

Wind farm. Click on picture for full size.Wind power is renewable energy source with very large potential and is the fastest growing renewable energy source. However wind power has certain disadvantages mainly because wind isn't steady source of energy since wind speed changes a lot, meaning there's no certain energy delivery system. But this could be easily changed by connecting wind farms
