We all love to flip through a glossy, interesting magazine on the plane, in the dentist’s waiting room, or stretched out on the sofa in the evening. It is now impossible to take all your reading material in your hand luggage and what if you are working in the field, in a foreign country far from a local newsagent or just do not fancy contributing to the world losing another tree.
We will deliver you a digital magazine to read on your, iPad, iPhone, Smartphone, PC or Kindle. All corporate and premier members will be regular contributors, with a primary focus on the implementation, financing, exploration and development of existing renewable energy technology, and new alternative energy. Our mission is to help innovation, creativity, finance and integration of all things renewable.
Our Mask-Africa E-Magazine, will focus on all types of renewable energy, the definitions are described here by Mask-Africa and in part by the Department of Energy and the National Renewable Laboratory.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun’s heat also drives the winds, whose energy, is captured with wind turbines. Then, the winds and the sun’s heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydroelectric power.
Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called bioenergy.
Hydrogen also can be found in many organic compounds, as well as water. It’s the most abundant element on the Earth. But it doesn’t occur naturally as a gas. It’s always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth’s internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean’s tides (tidal power)come from the gravitational pull of the moon and the sun upon the Earth.
In fact, ocean energy comes from a number of sources. In addition to tidal energy, there’s the energy of the ocean’s waves, which are driven by both the tides and the wind. The sun also warms the surface of the ocean more than the ocean depths, creating a temperature difference that can be used as an energy source. All these forms of ocean energy can be used to produce electricity.
