That concentration, combined with the rapid and increasing demand, could significantly raise prices. More problematic is the warning given by Meridian International Research that there are not enough economically recoverable lithium to build the number of batteries needed in a global economy of electric vehicles. Recycling could change the equation, but the economics of recycling depends in part if the batteries are made with easy recycling in mind, a problem of which the industry is aware. Use long-term Platinum also depends on recycling; the current available reserves could keep annual production of 20 million fuel cell for vehicles, together with the existing industrial uses, at least for 100 years. Smart mix for a new infrastructure sustainability must provide energy at least as reliable as the existing infrastructure. WWS technologies generally suffer less stopping time than traditional sources.
EE UU coal-fired plants are, on average, 12.5% offline a year for scheduled and unscheduled maintenance. Modern wind turbines have a stop time less than 2 per cent on the ground and less than 5% offshore. Photovoltaic systems are also unemployed less than 2 per cent. In addition, when a turbine wind, solar or inverter does not work, only a small part of the installation is affected and their loss represents a small fraction of production; When you lose your connection a plant’s natural gas or coal, or nuclear, a large part of the production is lost.The main challenge of the WWS, is that the wind does not always blow and the Sun does not always shines in a particular location. Flashing problems can be mitigated by a smart balance of sources, as a base with geothermal or waves and tidal generation or storage of the Energia. The wind is often abundant at night when there is no sun or solar for the day when there may not be wind. Other times a reliable source like hydropower can connect or disconnect quickly to meet the demand peak or reduce the supply.
