Organizing Energy

By: Jessica Robertson

When we think about renewable energy, few downsides come to mind. Wind parks, solar energy, biogas, and other renewable sources have inspired us and reminded us that we can make wise choices for our planet. The variable nature of these renewable sources, however, does mean that their levels of energy production on a day-to-day and month-to-month basis will inevitably undergo fluctuation. In order to bring the highest level of efficiency to the power grid, these fluctuations must be accounted for and the sources combined in an intelligent way.

            Researchers strongly agree that a model that relies heavily on variable and renewable energy sources can still be a perfectly viable model, though more organization is needed than for traditional power supply. Dr. Kurt Rohrig, deputy director of the Fraunhofer Institute for Wind Energy and Energy System Technology IWES in Kassel, Germany, and other experts, assert that by using numerous small energy producers that feed into the grid at varying times, the grid can be made highly reliable. This requires a major shift from the current system where big power plants are king, but change is inevitable when the environmental paradigm is shifting as quickly as it is currently.

            The multitude of small energy providers in the new concept would all be grouped in an intelligent software program, causing them to resemble a power plant, but a virtual one. Tests conducted using the software saw deeply promising results. The variations in sun and wind that make power production unpredictable in one locale can be leveled out to an appropriate average when including a larger number of smaller plants through the software.

            Proper organization of renewable energy sources and the power that they produce impacts the planet profoundly. We can reduce the waste and pollution left behind by dirtier forms of energy production by efficiently and intelligently using these environmentally friendly systems. 

An Environmental Story of Resiliency and Commitment

By: Jessica Robertson

The U.S. state of California has long been a leader in hydroelectricity production, but in 2013, a major drought dropped the state to its lowest levels of hydroelectricity production in over two decades. But, how did they manage to keep the power flowing without water? The state’s commitment to clean energy and a never-die spirit keep pushing them through with hardly a worry.

            Even though the drought has hit agriculture and water tables hard, the state can lean on its good planning, natural gas, and newly introduced renewable energy sources to keep the lights on. With prior experience in energy crises, California regulations do well to prepare for even the worst-case scenarios; so, spirits are high.

            The boost in renewable energy programs, like solar and wind power and even geothermal energy, has helped ease the burden of the drought. These new initiatives, specifically, have bolstered the energy-generation capacity; the pressure caused by the lack of hydroelectricity in the time of drought has amped up the importance and efficiency of these relatively new projects.  However, sunshine and wind cannot be called upon on a whim; natural gas has stepped in to provide the energy when the renewable resources cannot.

            Recent rain and snowstorms have hinted that the drought may be on its way out. However, the precipitation totals are incredibly lower than average, leaving a long way to go before danger is at bay and before energy costs can remain low. Experts say that even though the recent storms have brought much-needed relief, it may take up to a year to see real recovery. The state is hopeful that despite the drought, if it is here to stay, they can remain committed to clean and renewable energy.
