So, yes, solar alone could replace fossil fuels. We expect this could reduce energy and emissions by 20-30% compared to current iron-making processes, by replacing carbon-based fossil fuels with solar energy… "Renewable energy is the cheapest form of new energy build," Anna says. The Clean Energy Council wants Australia to use more renewable energy.

Although the environmental hazards of burning coal and other fossil fuels are widely known, the global community has been slow to adopt solar energy and other alternative power sources on a broad scale. The wind doesn’t always blow and the sun doesn’t always shine. There is no longer any sensible reason to continue to drill in environmentally sensitive areas.

It is vital to replace fossil fuels because they currently produce the majority of the world’s energy. I assume he was addressing my fundamental point that solar and wind cannot effectively replace fossil fuels as our main energy source. We need consistent, reliable energy. Maureen McCann, a professor of biological sciences, is studying a wide range of plants from poplar trees to zinnias. That would be far more than enough. Can renewable energy really replace fossil fuels? Could Solar Alone Entirely Replace Fossil Fuels? 1/ What kind of energy do we want? The U.S. Energy Information Agency compiled the … Only fifty years of fossil fuels remain and without a sensible energy policy, the world is doomed to progressively worse climate-related weather events. For example, if the researchers can modulate the strength of the "glue" between plant cells, they can make it easier for enzymes to access cellulose and also reduce the amount of energy needed for shredding the plant material. That is not an exaggeration, that is a reality. How solar energy can replace fossil fuels. As of 2012, the entire world used 17.7 terawatts for the year. The current energy system in the United States, Canada and globally is heavily dependent on fossil fuels – they generally supply over 80% of existing energy needs in developed countries and over 87% in the world as a whole. You stated: “Prior to the use of fossil fuels the total available energy supply available to humans was limited to energy obtainable from wind, solar, hydro, animals and slaves.” While I respectfully agree with most of what you have written, I note that there is one more source of energy that early humans used, and that is what is now called ” biomass”. A Purdue University scientist is studying the role of plants in renewable energy sources.

The Council's Director of Energy Generation Anna Freeman says solar is a great place to start. The answer is yes, according to experts at NREL. Currently, wind and solar energy sources constitute only one-third of one per cent of global energy supply. If we were able to capture 100% of the sunlight the earth gets each day, would that be enough solar power to replace the fossil fuels that the world uses in that day?
