Investment in Clean Energy Production Predicted to Rise

It is predicted that the use of solar and wind power will rapidly increase as costs falls. There has been an improvement in the efficiency of wind turbines. Solar panels also put out more power at a lower cost.

Australians have strongly adopted solar power while governments offer high payments for electricity going back into the system. Making an end date of 2026 of such overpayment was a silly idea. It is too far ahead for future governments to guarantee this "lopsided" subsidy that only helps the wealthy. The financial burden has been pushed onto the elderly.

Solar power has hidden costs. Power surges burn out televisions and computers. New ones must be purchased. Many consumers are saying someone has to fix this. Considering solar power generation will fluctuate throughout the day with this is near impossible.

Frank Calabria, CEO of Origin Energy, favors the elimination of all subsidies on clean energy. This indicates a probable back down considering Origin is the largest investor in wind farms. Coal remains the cheapest form of power production in Australia. This economic advantage will continue. Whether new calls for nuclear power are supported is unknown are present.

Bees Calculate Energy Expended When Getting Pollen

Bees calculate how much energy they need to get pollen. To survive, bees must run on a "profit" basis. They must not use more energy in obtaining nectar than energy the nectar provides. Bees were given the choice of travelling along two pathways to get nectar. One pathway was 10 meters long, the other 20 meters. However, the "scenery" of the 10 meter pathway was designed to trick the bees into perceiving that it was the furthest distance away.

When the bees returned to their fellows in the nest they told them with a waggle dance which pathway to use to get more pollen. Despite the 10 meter pathway appearing to the bees to be further away they told other bees to go to the feeder in the 10 meter pathway. Somehow, they had worked out that it used up less energy to go to this feeder than the one on the other pathway.

It is believed that bees have "calorimeters" built into their brains. They do not judge energy expenditure solely based on distance travelled. A partly covered pathway would be given the okay over a pathway out in the weather for example.

Bees are smart little critters and we can learn a great deal from them.
