Roofers and Contractors Overbooked in Preparation for El Nino Winter



After months of drought conditions throughout California, homeowners are rushing to get their houses prepared to withstand the expected onslaught of the upcoming year of El Nino weather. Many of these homeowners are coming to realize that their roofs should be patched up or replaced before the "above-average" rainfall begins. The National Weather Service predicted that the Los Angeles and San Diego areas this winter will have about a 60-69% chance of "above-normal precipitation," which is a huge wake-up call for Californians who have experienced very little rain over the past couple of years. Ronald White, in his L.A. Times article, investigates the current rush to get ready for the winter season and the strain it has been putting on various businesses.

While many people are seeking roofers for long-overdue work on their roofs, other workers, like gutter repairers and tree trimmers, have also reported that 10 times the number of requests for their services have been made this year than the last. while the increased demand is great for business, many have been unable to keep up with demand, leaving property owners disappointed. Many homeowners have even reported difficulty getting an estimate for potential work, let alone getting contractors to their home to get the work done. Many roofing and construction companies have full waiting lists through March, but an appointment that late won't really help a homeowner trying to prepare for the El Nino winter.

Even arborists and tree services have full schedules, booked by homeowners and others worried about whether draught-stressed trees fall in the winter, potentially injuring people and destroying property. Companies like the Your Way Tree Service go out and check trees for health, as many are already dead due to disease, wood rot, or lack of water. The tree service determines whether trees are healthy enough to withstand the winter, and, if not, they fell them safely so that rough winds won't do it later.

Finally, there are those people who plan to use the rainfall later, when El Nino is over. Even they have been having trouble finding experts to install rainwater storage systems on their properties. Not only are some of these specialists booked, many others are unwilling to start work in L.A. until the demand has died down somewhat. However, they still encourage homeowners to keep calling. Eventually, they will be able to get through to a professional who is able to help them. Everyone right now has to turn away business because they simply don't have enough manpower or hours in the week to get work done for everyone.

Steve Lang, of the Roofer Contracting Association, warns homeowners against desperation. He assures them that they will eventually be able to get an appointment with a professional who knows what he/she is doing. His warning is this: hiring an unknown contractor or roofer to do work on your home could end up costing you much more in the long run, usually due to shoddy work by an inexperienced roofer or other kind of worker. He reminds homeowners to look for licensed professionals. Just because someone claims to be a roofer doesn't mean that their work will protect your home from the coming winter's rain. It is far safer and more cost-effective to be patient and wait for someone who knows what they are doing.

Drought Conditions Prevent Ability to Store Sustainable Energy



For companies like Southern California Edison, the drought is taking its toll on their sources of sustainable energy. When water stored in artificial lakes high in the mountains is released, it flows down to turn hydroelectric turbines and convert the water's kinetic energy into electrical energy for use by consumers. This system only works when the water is available for use. Because of the drought, water levels have dropped so far that the hydroelectric system has been put on hold for the time being. According to Ivan Penn, in his L.A. Times article, the hydroelectric power is not the only source of power being lost due to depleted water reserves.

Renewable resources are those that are considered to be constant in nature, that will always be available on Earth. Sunlight, wind, and water are some examples of such resources. You may ask, “Why is water considered 'renewable' if a drought can reduce the amount available?" This is due to the fact that, while a drought reduces the availability of water in specific parts of the world, the amount of water available throughout the entire world remains relatively constant. 

As more and more research comes out showing the negative effects that coal and fossil fuels have on the environment, as well as the rapidly diminishing supplies of such resources, both government agencies and private corporations search for a more sustainable alternative. Wind and solar energy seem to provide the greatest return on investment, to the extent that many homeowners have installed their own solar panels to harness the Sun's natural power for themselves. Unfortunately, power companies have yet to find a way to store excess energy. Just as blackouts and power reductions can be caused by too little power being produced, too much power can overload the power grid and damage everything connected to it.

Edison has a system that, in non-drought times, would be quite effective in storing excess energy for later use. when the water has flowed down the mountain and through th3e turbines, it ends up in another manmade lake. When their solar panels and wind turbines collect more energy than can be used by consumers, the excess energy is used rather than given away at negative prices. The energy is used to power pumps that bring the water back up the mountain and stored back in the starting lake. In this way, "energy" can be stored, though not in the classical sense.  Since energy can only be converted, not created or destroyed, the excess energy is converted from electrical to mechanical (pumps) to potential (water on top of the mountain). Then, when the energy is needed again, the water is released from the lake and the potential energy becomes kinetic, then electrical once again. 

At nighttime, stored energy is needed to make up for the fact that no solar energy is being collected. While Edison's energy storage system, of course, has loss associated with it, since all processes lose some energy as heat, it is better than the alternative in which excess energy is given away to competing companies in order to prevent overloading of the power grid. However, drought conditions have everyone at a loss. How else can the energy be stored in an economical, efficient, and environmentally-friendly manner?  

As Penn points out, it's not as if we can control Sun or wind on command. Renewable energy sources are great and have become more utilitarian and widely used in recent years, but it seems that the most effective use of researchers' time would be to find a better way to store the energy.  If renewable, sustainable energy can be stored and easily accessed, then there would be little reason to use fossil fuels and other degradative materials as energy sources. As such, solar, wind, and hydroelectric power are arguably the best and cheapest energy sources, but they can only live up to their true potential if scientists find an effective way to store the excess.
