    In a world where almost everything is run by machines it not surprising that we are also running out of energy sources what worsens the case is that the energy sources that we use are destroying the world we are living in. Another dilemma people are now facing is these energy sources are bound to vanish years from now.

    The potential of renewable sources is massive as they are expected to meet world’s energy demand. Renewable energy sources are biomass, hydropower, geothermal, solar, wind and marine energies they can provide sustainable energy services, based on the use of routinely available, indigenous resources. The renewable resources such as biomass, wind, solar, hydropower, and geothermal can provide sustainable energy services, based on the use of routinely available, indigenous resources are attractive renewable fuel in utility boilers.


    While price of gas continue to fluctuate a transition to renewables-based energy systems is looking increasingly likely as their costs decline. Solar and wind powers continue their rapid sales growth in the past 30 years. Due to this their capital costs and costs of electricity generated, and have continued to improve their performance characteristics while fossil fuel and renewable energy prices, and social and environmental costs are heading in opposite directions. The economic and policy methods needed to support the widespread dissemination and sustainable markets for renewable energy systems are evolving fast.


    Renewable energy sources (RES) supply 14% of the total world energy demand. The future growth in the energy sector will be primarily in the new regime of renewable energy, and to some extent natural gas-based systems and the conventional oil and coal sources will then die out. These developments will innovate the market opportunity to emerge and promote renewable energy technologies but of course with the assistance of governmental and popular sentiment.

    The thing is, that is not entirely true.
    The biggest problem is that even with a market that want renewable energy sources. We must still be capable of actually making them. Many of the high efficient renewable energy producers require rare earths which are very low on availability. This might make things more difficult in the future. In any case, what would always help is the reduction of energy cost. And that, is lifestyle. It could easily reduce our energy consumption by half.

    At the current rate of exploitation oil and gas will run out somewhere in 2050-2070.

    Is there any assurance that these renewable energy sources are reliable?

    Wind energy in itself is a source of renewable energy which means it can be produced again and again since it is available in plenty. It is cleanest form of renewable energy and is currently used many leading developed and developing nations to fulfill their demand for electricity.

    IMO, a balance of Solar, Wind, and Tidal power could provide energy for the entire planet. Where grids are impractical, personal units could be used singly or in series.

    I quite like some of the more exotic ideas for energy generation such as sonoluminescence, in layman's terms using sound to collapse gas bubbles within liquids, that seem to offer a clean and easy source of energy. There is even suggestions that we may be able to use sonoluminescence to harness quantum vacuum radiation because some theories are predicting the rapidly moving interface between water and gas can convert the virtual photons, because quantum theory holds that vacuums contain virtual photons, into real photons.

    I think technologies like this offer some interesting advantages over solar, wind and wave energy technology, such as not being dependent on weather conditions to function and also the potential to be scaled up or down as necessary.

    I hope every one starts to use this renewable energy before it’s too late. Energies that we know now will be gone soon. 2050 they say. Best of luck to us.1.

    Of course it isn’t too late yet. 2050 is still a long way to go but that doesn’t mean we have an excuse not to act now. It wasn’t indicated here but there are ways on how we can help, an ordinary citizen like us can make a big change.

    How sure are we that these renewables are really consistent and reliable? Like solar energy, it definitely has flaws. It is not always sunny.

    Hey, hi. The purpose of these energy resources, the renewables is to become an alternate to the energy resources that we currently use to prolong its life.

    Have a look at where renewables are now at this link. IRENA | Press Releases

    Do you really think we can afford to use them? We are living in a past pacing world, everyone is busy. Time is essential to everyone.

    Afford it? Pretty soon we'll be asking whether we can afford to do it any other way. Remember the power plants we have will not last more than a few decades at most. They have to be replaced, some time or another. The question is what will we replace them with. In America at least, cheap gas has meant that no new or replacement coal plants have been built for 2 years or so. And new emissions rules could mean that most renewables are already cheaper than a new coal plant.

    Biomass power generation has become competitive wherever low-cost agricultural or forestry waste is available, with the most competitive projects producing electricity for as little as USD 0.06/kWh.
    • Concentrating solar power, in which mirrors focus light over a large area into a central generator, has seen costs drop to as little as USD 0.14/kWh.
    • Hydropower, currently the world’s largest source of renewable energy, today often provides the lowest cost electricity of any generation source.
    • Solar photovoltaics (PV), which has seen rapid development over the past two years, is set to achieve grid parity with residential electricity tariffs in many locations around the world. PV costs typically range from USD 0.16 to 0.36/kWh.
    • The most competitive onshore wind power sites can deliver electricity costs at as little as USD 0.04/kWh. (note: the best great plains sites in the US are down to 0.03, with more savings expected – PS)

    By way of comparison, electricity generated from fossil fuel typically costs between USD 0.06 and 0.12/kWh in OECD countries – excluding the cost of transmission and distribution.

    We need to get away from this destroy stuff and burn it approach.

    In the Stone Age, we were picking up sticks or digging up peat, and burning it.
    For centuries, we were cutting wood from forests, and burning it.
    In the 17th century we were killing seals and whales so we could get their oil, and burn it.
    In the 18th century we were digging up coal, and burning it.
    In the 19th century we were digging up oil, and burning it.
    In the 20th century we were digging up uranium, and burning it.

    Now that the 21st century is here, we have a real opportunity to stop destroying stuff, and burning it.

    Hello, I don't have problem with renewable energy resources. In fact I am a supporter because I understand the hazards energy sources we are using now. The only problem is we cannot be dependable on it alone because it cannot support the world's demand.

    Hi, Ii understand your argument but think of these if some of the people is not all will use the renewable energy resources for sure it will be a great help on earth, human health, environment and it can even help to save the dying sources of the current energy resources we are using.

    It begs the question: Have any numbers been crunched on how much usage is needed to really have an effect?

    Considering all the talent that frequents this forum, has anyone thought about starting a sub-forum devoted ideas on how to replace fossil fuels? There must be a lot of ideas floating around out there that, if brought together for review and constuctive criticism, may lead some unknown genius to devise a method of producing a cheap energy source, whatever it may be?

    I don't see the connection, but who knows? Speaking of "Connections", I was thinking along the lines of the James Burke series that explained how seeming unrelated ideas and inventions come together to create entirely new inventions and processes. If enough ideas are presented for review and adaptation, perhaps some connection will be made that can be applied to the energy problem.

    I meant to bring attention to the growing field of asking gamers and programmers to participate in specific scientific research on-line. Check it out.

    Maybe the best thing that people should do is develop these energy resources, these renewable, so that we can use the most out of it.

    Solar energy is the answer to world’s energy problems. Solar energy is renewable source of energy and it has no specific requirements and can be used in house holds, offices, factories etc. Also government is paying to install solar panels as they are little expansive but researches are going on to reduce the cost of solar panel.
