Mark Ruffalo Wants You To Imagine A Cleanly Powered Future

Mark Ruffalo is a strong advocate of environmental conservation, and has focused on activism against hydraulic fracturing, which is a relatively recent extraction method for natural gas. Opponents of hydraulic fracturing are concerned that it causes severe water pollution and earthquakes.

Hydraulic fracturing is highly controversial. Some still consider natural gas to be relatively clean. However, as scientists get past this learning stage, they may or may not find that hydraulic fracturing really is a serious environmental problem. It’s better to find out via testing, rather than an outbreak of toxicity, which is why hydraulic fracturing should have undergone more careful analysis before implementing it on a large scale.

Dip your toe in the water before jumping in. Caution is a virtue!

Mark Ruffalo advocates transitioning to renewable energy instead, especially solar power, wind power, and hydroelectric power.

While there are people who try to drum up the issue of renewable energy “intermittency,” wind and solar power plants are not carelessly integrated into the electricity grid without backup or energy storage. All power stations are backed up with peaking power plants which can start in only 15 minutes to provide power while other power plants are being repaired. The uptime for “baseload” thermal power plants is in the 70% to 90% range, so they rely on backup/energy storage as well. Coal and nuclear power plants are actually barely adjustable, resulting in the need for peaking power plants to augment electricity production when electricity demand increases during the afternoon.

Hydroelectric power plants are the only truly reliable power plants that don’t require backup. However, their use is limited to regions that are not environmentally sensitive.

But what matters most for many electricity customers is cost. According to the Department of Energy’s NREL, wind power is only 9.7 cents per kWh without subsidies, while coal is 9.4, so it won’t increase electricity bills much on average. Furthermore, coal comes with health costs that total another  9 –27 cents per kWh, according to a study led by the Director of Harvard Medical School Center for Health and the Global Environment. So, coal is actually much more expensive.

Apart from that, solar and wind energy can be utilized with no energy storage or backup for certain applications, as far-fetched as that may sound. For example: Solar thermal water heaters absorb sunlight which turns into heat, and then the water absorbs that heat. These units are very common, and I actually use one. A simple insulated tank keeps the water hot all night, so there are no “what if” questions about night-time.

Solar and wind power can also be used to pump water via electric water pumps. If you need to get water from point A to point B, you can set up a water tank at point B and use wind turbines or solar panels of adequate capacity to power the electric water pumps, so that they pump surplus water into the tanks. It can then flow back out of the tanks to whoever needs them.

Solar and wind farms can also power desalination plants and then pump the clean water into tanks afterwards, so there are no water supply interruptions. For regions which are not too far from the ocean, this could be a great way to set up a water supply. Desalination is very energy intensive.

It’s great to see Mark Ruffalo, perhaps better known as the HULK, using his star power to advocate for clean, reliable, safe, and cheap renewable energy.

  • Hello!
    Among the best energies of the future may be:

    1) The recycling of heat energy lost in many use examples Freezers <

    2) Conversion of the room temperature in a mechanical movement.

    Go out of Nuclear and Fossil Energy

    of Kneider


    The real go out of fossil fuels, fuels and nuclear energy does not lie in
    solar, wind or tidal, etc. … All the above alternatives are often a mismatch
    between supply and demand …

    The most appropriate output seems to be the thermal energy at room temperature,
    which illustrates Georges CLAUDE called the ETM Thermal Energy Seas.

    Georges Claude built a 60 kW power plant with a yield of 6% in cycle Carnot
    cycle, but 100% in reality. The only downside was the price of 3 million U.S.
    Dollars (period price), which proved economically utopian, unrealistic and
    catastrophic! But in terms of science and technology is a valuable step
    forward, non-measurable, comparable to the discovery of fire by Homo Erectus
    400,000 years ago…

    The thermal energy at room temperature as I develop nothing is revolutionary. It uses the principle of OTEC
    Georges Claude, adapted to the technology and know-how today.

    Tangible to take into account in relation to other forms of conversion
    requirements are: investment costs, depreciation, dependability, reliability,
    availability, weight etc. …

    In fact, any potential energy is converted into kinetic energy and ultimately
    into thermal energy at 100%. The reverse process is absolutely true …

    Take the example of a tennis ball that is dropped from a height of 2 meters, it
    will bounce a few times and it will end in a rise in the ambient temperature

    This cycle is completely reversible! Provided, however, that the means chosen
    to be economically viable…

    To meet this challenge, we need to take some liberties
    with the laws of thermodynamics, inherited from the 18th, 19th and 20th century
    and put us level with science, technology, techniques and know-how in force
    today. .. Here we are in the presence of a field of reflection and improvement
    that goes beyond stocks of fossil fuels, the opportunities offered by the
    nuclear or all kinds of alternativ

      “we need to take some liberties with the laws of thermodynamics

      Or we could simply take a break from reality….

    What I miss in clean energy option, is the use of air to water heat pump, for house warming and warm water.
    together with Solar panels. put 1 Kwh in get 4 out.
    like a slot machine, 1 dollar in 4 dollar out, you always win.
    and no use of fossil. all electric house.
    It really works.

      A great performance
