Renewable energy. Sounds like the ideal solution to our energy crisis—an endlessly replenishing supply to meet our insatiable demand. But is it cost-effective? One of the greatest obstacles in finding alternative fuel sources is that the cost of generating the fuel is often greater than what the fuel itself is worth. A recent study finds that in the near future, an energy system based entirely on renewable sources will be the most economically feasible. Tremendous effort has been expended in developing “green” systems that will be environmentally friendly and affordable.

Solar and wind energy will be the two cheapest sources of energy within the next decade, particularly in the Asian market, the “factory” of the world, which has the highest energy demand. This region also produces more pollution of the oceans, ground water and atmosphere than any other area of the earth.

A study by the Technological University of Finland showed that an energy system based entirely on solar and wind power is possible in Northeast Asia, and in China in particular. The cost of generating this energy will be cut in half by the year 2030, as efficiency increases.

In a spiritual vein, we find a similar phenomenon—energy that was used in the past is now seen as harmful and polluting, and the search is on for “cleaner” and more effective alternatives. For example, it used to be considered acceptable for countries to invade each other and settle their differences by force. Increasingly, the trend among nations is mutual cooperation and resolution of differences by negotiation. Strong nations step in to protect weaker nations from exploitation.

In the field of education, parents and teachers now recognize that aggressive methods such as hitting are harmful and leave scars on a child’s psyche. Today corporal punishment is almost universally frowned upon, and the emphasis is on tailoring the educational method to the child, by carefully considering his or her needs, character and personality. Rather than resorting to physical punishment, parents and teachers use a range of tools that build up rather than put down the child.

Overall, the trend is towards more positivity in our relationships with others, friends and strangers alike. It has become clear that it is healthier and more effective to live in an environment of friendliness and mutual cooperation. This approach has always been preferred by the Torah: “Its ways are ways of pleasantness and all its pathways are peace.”

We always knew this, but it didn’t really catch on until today. Finally we are seeing the effects of Moshiach in this world. The final preparations have been completed and we are ready to usher in an era filled with light and spirituality, peace and brotherhood—the era of Redemption.
