Renewable Energy Sources Important Quotes

Similarly, replacing fossil fuels with renewable energy sources is likely to appeal to some countries more than to others. China, Japan, and South Korea depend on importing huge quantities of oil and gas. They will be delighted to be free of that burden. Russia, Iran, and Saudi Arabia depend on exporting oil and gas. Their economies will collapse if oil and gas suddenly give way to solar and wind.

RENEWABLE ENERGY REVOLUTION: SOLAR + WIND + BATTERIES In addition to AI, we are on the cusp of another important technological revolution—renewable energy. Together, solar photovoltaic, wind power, and lithium-ion battery storage technologies will create the capability of replacing most if not all of our energy infrastructure with renewable clean energy. By 2041, much of the developed world and some developing countries will be primarily powered by solar and wind. The cost of solar energy dropped 82 percent from 2010 to 2020, while the cost of wind energy dropped 46 percent. Solar and onshore wind are now the cheapest sources of electricity. In addition, lithium-ion battery storage cost has dropped 87 percent from 2010 to 2020. It will drop further thanks to the massive production of batteries for electrical vehicles. This rapid drop in the price of battery storage will make it possible to store the solar/wind energy from sunny and windy days for future use. Think tank RethinkX estimates that with a $2 trillion investment through 2030, the cost of energy in the United States will drop to 3 cents per kilowatt-hour, less than one-quarter of today’s cost. By 2041, it should be even lower, as the prices of these three components continue to descend. What happens on days when a given area’s battery energy storage is full—will any generated energy left unused be wasted? RethinkX predicts that these circumstances will create a new class of energy called “super power” at essentially zero cost, usually during the sunniest or most windy days. With intelligent scheduling, this “super power” can be used for non-time-sensitive applications such as charging batteries of idle cars, water desalination and treatment, waste recycling, metal refining, carbon removal, blockchain consensus algorithms, AI drug discovery, and manufacturing activities whose costs are energy-driven. Such a system would not only dramatically decrease energy cost, but also power new applications and inventions that were previously too expensive to pursue. As the cost of energy plummets, the cost of water, materials, manufacturing, computation, and anything that has a major energy component will drop, too. The solar + wind + batteries approach to new energy will also be 100-percent clean energy. Switching to this form of energy can eliminate more than 50 percent of all greenhouse gas emissions, which is by far the largest culprit of climate change.

Any version of the widely discussed Green New Deal project must include these priorities: 1. Greenhouse gas emissions reductions will at least achieve the targets set in 2018 by the Intergovernmental Panel on Climate Change, namely a 45 percent reduction in global emissions by 2030 and the attainment of net zero emissions by 2050. 2. Investments to dramatically raise energy efficiency standards and equally dramatically expand the supply of solar, wind, and other clean renewable energy sources will form the leading edge of the transition to a green economy in all regions of the world. 3. The green economy will not expose workers in the fossil fuel industry and other vulnerable groups to the plague of joblessness and the anxieties of economic insecurity. 4. Economic growth must proceed along a sustainable and egalitarian path, such that climate stabilization is unified with the equally important goals of expanding job opportunities and raising mass living standards for working people and the poor throughout the world.

The main theme of Goddess symbolism is the mystery of birth and death and the renewal of life, not only human but all life on earth and indeed in the whole cosmos. Symbols and images cluster around the parthenogenetic (self-generating) Goddess and her basic functions as Giver of Life, Wielder of Death, and, not less importantly, as Regeneratrix, and around the Earth Mother, the Fertility Goddess young and old, rising and dying with plant life. She was the single source of all life who took her energy from the springs and wells, from the sun, moon and moist earth. This symbolic system represents cyclical, not linear, mythical time. In art this is manifested by the signs of dynamic motion: whirling and twisting spirals, winding and coiling snakes, circles, crescents, horns, sprouting seeds and shoots.

as fast, efficiently, deeply and cost-effectively as possible. Because we have spent so many pages exploring some of the weaknesses of renewable energy sources, one might think that we are somehow opposed to these energy sources. As we wrote in the introduction, this is not the case. Even though readability prevents us from stating this at every juncture, we wish to categorically state that we support (within environmental limits) all truly low-carbon energy sources and nearly all the energy efficiency proposals we've seen so far. Both of us have even invested our own hard-earned money in renewable energy generation. We will most certainly need a lot more renewable energy, and we are certain that they are being built. The question whether or not renewable energy sources could play a major role in our energy system has already been answered: we know that they will be important sources of energy in the future. The only question is how important. We, of course, hope for the best and are excited about the potential and various benefits of renewable energy, and believe that solar and wind energy are amongst the most important tools for successful climate change mitigation.
