A renewable resource is an organic natural resource which can replenish to overcome usage and consumption, either through biological reproduction or other naturally reoccurring processes. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. A positive life cycle assessment is a key indicator of a resource's sustainability.
Definitions of renewable resources may also include agricultural production, as in sustainable agriculture and to an extent water resources. In 1962 Paul Alfred Weiss defined Renewable Resources as: "The total range of living organisms providing man with food, fibres, drugs, etc...". Another type of renewable resources is renewable energy resources. Common sources of renewable energy include solar, geothermal and wind power, which are all categorised as renewable resources.
Water can be considered a renewablematerial when carefully controlled usage, treatment, and release are followed. If not, it would become a non-renewable resource at that location. For example, groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge, and so groundwater is considered non-renewable. Removal of water from the pore spaces may cause permanent compaction (subsidence) that cannot be renewed. 97.5% of the water on the Earth is salt water, and 3% is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction (0.008%) present above ground or in the air.
Richard Heinberg (born 1950) is an American journalist and educator who has written extensively on energy, economic, and ecological issues, including oil depletion. He is the author of twelve books. He serves as the senior fellow at the Post Carbon Institute.
Heinberg, after two years in college and a period of personal study, became personal assistant to Immanuel Velikovsky in November 1979 and after Velikovsky's death assisted Mrs. Velikovsky editing manuscripts. He published his first book in 1989, Memories and Visions of Paradise: Exploring the Universal Myth of a Lost Golden Age, which was the result of ten years of study of world mythology. An expanded second edition was published in 1995. He began publishing his alternative newsletter, the MuseLetter, in 1992. His next book was published in 1993: Celebrate the Solstice: Honoring the Earth's Seasonal Rhythms through Festival and Ceremony.
In June 1995, speaking to the International Society for the Comparative Study of Civilizations in Dayton, Ohio, Heinberg provided "A Primitivist Critique of Civilization" and discussed the ways in which "We are, it would seem, killing the planet."
It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy. In countries like Brazil, Australia, Chile and parts of the United States people consider renewable energy because of financial reasons. The price of solar and wind energy will continue to drop and in more countries renewable energy will occur. A surprising newcomer on the market is Morocco, where the government expects that in 2020 more than 40 percent of the energy could come from solar energy.

( This isn't a sponsored video, but I am massively grateful to all the team at SSE! Go look: http://sse.com/whatwedo/ourprojectsandassets/ , and pull down the description for more. ) As the world switches to renewable energy - and we are switching - there's a problem you might not expect: balancing the grid. Rotational mass and system inertia are the things that keep your lights from flickering: and they only appear in big, old, traditional power stations. Here's why that's a problem, and how we're likely going to fix it. Thanks to all the team at SSE!

Richard Heinberg is Senior Fellow-in-Residence of the Post Carbon Institute and is widely regarded as one of the world’s foremost educators on peak oil, energy policy and community resilience. In this Jamaica Plain Forum, Heinberg explores the opportunities and challenges of a transition to a fossil fuel free future. Several energy analysts and environmental organizations have formulated plans for transitioning to 100 percent renewable energy. Heinberg, along with David Fridley, staff scientist of the energy analysis program at Lawrence Berkeley National Laboratory, has gathered and assessed those plans. In his talk, Heinberg discusses the future of clean energy and how the characteristics of ~100 percent renewable energy would shape our lives and economy.
As the world is becoming more conscious of the effects of climate change, our sources of energy are coming under scrutiny. Governments are struggling to become less dependent on fossil fuels which traditionally fuel our economic growth. What will be the future sources of energy? In this session, we explore how would we be able to stop our dependence on fossil fuels, create a healthy environment while generating a prosperous economy. Justin Hall-Tipping, Chief Executive Officer of Nanoholdings.
Simple devices made of bacterial spores, glue, and plastic may allow capturing energy from evaporating water.

028 - Renewable Energy In this video Paul Andersen discusses the technology, advantages and disadvantages of six sources of renewable energy; biomass, hydroelectric, solar, geothermal wind, and hydrogen. He also explains how changes in the storage and flow of energy in our power grid must be improved. He also lists the energy returned over energy invested ration for the various forms of energy.

ISLE OF CAPRI
Ray Noble
'Twas on the Isle of Capri that I found her,
Beneath the shade of an old walnut tree,
Oh, I can still see the flowers blooming 'round her,
Where we met on the Isle of Capri.
She was as sweet as the rose of the dawning,
But somehow Fate hadn't meant her for me,
And tho' I sailed with the tide in the morning,
Still my heart's on the Isle of Capri.
Summertime was nearly over,
Blue Italian skies above,
I said, "Lady, I'm a rover,
Can you spare a sweet word of love?"
She whispered softly, " 'Tis best not to linger,"
Then as I kissed her hand I could see
She wore a plain golden ring on her finger,
'Twas good-bye to the Isle of Capri.
