What Is Photosynthesis? From Light Energy to Chemical Energy

Renewable sources of energy which do not alter global energy levels are therefore desirable.

Solar energy drives photosynthesis to form plant ..

Brookhaven researchers are also developing an understanding of how catalysts work in the complicated processes needed to replicate photosynthesis, including carbon dioxide transformation to fuels. If they can find catalysts that are both efficient and inexpensive to do the job, then they may bring the world a big step closer to tapping the sun’s energy.

Photosynthesis: A new source of electrical energy? …

Biofuels are produced from living organisms or from metabolic by-products (organic or food waste products). In order to be considered a biofuel the fuel must contain over 80 percent renewable materials. It is originally derived from the photosynthesis process and can therefore often be referred to as a solar energy source. There are many pros and cons to using biofuels as an energy source. This page contains articles that explore the many biofuel technologies.

Most Americans, however, use solar energy in its secondhand form: . When sunlight strikes a plant, some of the energy is trapped through photosynthesis and is stored in chemical bonds as the plant grows. Of course we can recover that energy directly months or years later by burning plant products such as wood, which breaks the bonds and releases energy as heat and light. More often, though, we use the stored energy in the much more concentrated forms that result when organic matter, after millions of years of geological and chemical activity underground, turns into , , or . Either way, we’re reclaiming the power of sunlight.


Artificial Photosynthesis Transforms Solar Energy into ..

Solar energy conversions through the use of photosynthetic microorganisms do not incorporate the use of complex systems or large quantities of factory manufactured products, and indeed have relatively minimal investment and resource requirements.

By achieving better than one-percent efficiency in “artificial photosynthesis” in the laboratory — a better efficiency than that of plants — scientists could produce significant amounts of clean, renewable energy, but the challenges to overcome are difficult. While plants use chlorophyll to absorb sunlight, scientists use a photo-electrochemical cell to absorb light and to separate charges. The separated charges initiate complex chemical reactions that store the solar energy as fuels such as hydrogen or methanol. Brookhaven chemists are working on finding stable, visible light absorbing materials for the cell’s anode.

Recent advances in biotechnology have made possible studies on the utilization of biological processes such as photosynthesis for energy production.The use of natural energy involves the control of entropy.

Efficient utilization of energy from the sun may provide a solution to this important problem. The amount of clean, renewable energy derived from the sun in just one hour would meet the world’s energy needs for a year. If we can convert solar energy to fuels with only ten percent efficiency — and use two-tenths of a percent of land in the world for that purpose — we can meet more than 60 percent of the world’s need for energy. While no single source will solve the energy problem, converting solar energy to fuels could be a large part of the solution.

With the help of photosynthesis plants convert light energy to chemical energy. This chemical energy is stored in the bonds of sugars they use for food. Photosynthesis happens inside
