三種能源收集工具在提高能源效率方面是可行的

　　隨著能源成本的上升，電源制造商努力提高效率、減少熱量和降低電氣成本。而節約能源很重要，能量收集裝置，將能量從環境–太陽能、熱能、風能、鹽度梯度，和動能轉化為電能并儲存起來–小，低能電子被證明對于許多應用越來越可行。

　　能量收集裝置根據它們收集的能量的數量和類型而有所不同。例如，從一個人的振動和運動（即動能）可以提供約4μW / cm2能從皮膚表面溫度差能源收獲（熱電能量）可以提供25瓦/厘米2μ。光伏能源–捕獲光–提供約10μW / cm2室內照明和10毫瓦/厘米2室外。最大的機會可能是從工業中獲取能量。熱電能源創造了行業可以提供高達10毫瓦/厘米2和動能可以提供高達100瓦/厘米2μ。

　　The eZ430-RF2500-SHE is a complete solar energy harvesting development kit from Texas Instruments to help create a perpetually powered wireless sensor network. Based on its ultra-low-power TI MSP430 microcontroller， the solar energy harvester module includes a high-efficiency solar panel optimized for operating indoors under low-intensity fluorescent light. This provides enough power to run a wireless sensor application with no additional batteries. Inputs are also available for external energy harvesters such as thermal， piezoelectric， or another solar panel. The kit includes a USB debugging interface and a battery pack with expansion board.
