#Balancing renewable energy costs and optimizing energy mix Increasing reliance on renewable energies is the way to achieve greater CO2 EMISSION sustainability and energy independence.
As such energies are yet only available intermittently and energy cannot be stored easily most countries aim to combine several energy sources.
In a new study in EPJ Plus French scientists have come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources.
Although recognised as crude by its creator this method can be tailored to account for the public's interest-and not solely economic performance-when optimising the energy mix.
In their model the energy demand and availability are cast as random variables. The authors simulated the behaviour of the mix for a large number of tests of such variables using so-called Monte-carlo simulations.
For a given mix they found the energy cost of the mix presents a minimum as a function of the installed power.
In contrast if it is too small expensive energy sources need to be solicited frequently. The authors are also able to optimise the energy mix according to three selected criteria namely economy environment and supply security.
The simulation tested on the case of France based on 2011 data shows that an optimal mix is 2. 4 times the average demand in this territory.
This mix contains a large amount of nuclear power and a small amount of fluctuating energies: wind and solar.
Bacteria decompose the mixture and produce among others the energy-rich gas of methane. It is used then for the gas stoves in the kitchen of the hospital.
and consumes no energy until readings are being made she said. In the short term we hope to use devices like this to track packages

Building on last year findings, Sahin and his Columbia colleagues sought to build actual devices that could be powered by such energy.
while a flow battery system is appropriate for battery chemistries with a low energy density (those that can only store a limited amount of energy for a given weight),
for high-energy density devices such as lithium-ion batteries, the extra complexity and components of a flow system would add unnecessary extra cost.
even better, that can extract energy from the environment to recharge. Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it,
even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.
Nonetheless, the chip power consumption remains low. e still want to have battery-charging capability, and we still want to provide a regulated output voltage,
since the rate at which it dissipates energy as heat is proportional to the square of the current.
because there a fixed amount of energy that consumed by doing the work, says Brett Miwa,
