Lignin is a cheap, abundant and non-toxic group of complex phenolic polymers obtained in large amounts from the papermaking and cellulosic biofuel industries. Although the application of lignin has been ex- plored in these and several more industries, there are limited applications of lignin in the energy industry. However, numerous research revealed a great interest in the exploration of this renewable biopolymer in storage energy devices. Some of these applications include the use of lignin as an expander for lead-acid batteries, electrodes for primary and rechargeable batteries, electrodes for electronic double layer capac- itors and electrochemical pseudocapacitors, and to feed different types of fuel cells. The use of lignin in energy storage devices improves not only the performance of these devices but also decreases the price and toxicity, contributing to obtaining greener energy devices. Based on the above, this review provides an overview of the main research work related to the use of lignin as a renewable component, suitable to replace some synthetic and toxic compounds used in the fabrication of energy storage devices with particular emphasis on batteries, advanced supercapacitors, and solar and fuel cells.

GM （genetically modified） corn with the CrylAb, mCry3A and Vip3Aa20 protein of Bt （Bacillus thuringiensis） and its respective isoline as control with and without chemical control for corn earworm were used in this research. Fusarium corncob damage was lower on GM corn with （12.5%） and without （25.7%） insecticide treatment as compared with the isoline that had 48.3% and 83.1% of damaged corncobs with and without chemical control, respectively. Corn smut cob damage was also lower on GM corn with （3.2%） and without （6.3%） insect control compared with 15.5% and 49.7% damage with and without insecticide treatment, respectively. Fusarium sp. corncob rot was also lower on GM corn with 5.7% and 9.5% whereas a 24.6% and 63% rot was observed on the isoline with and without insecticide control, respectively. Ustilago maydis severity was also lower on Bt corn finding 0.07% and 0.25% damage on treatments with and without insect control as compared with the isoline that showed an 11.6% and a 41.4% smut rot with and without insecticide treatment, respectively. The authors conclude that GM corn resistant to Helicoverpa zea prevents damage by the pest, eliminating the entrance pathway for Fusarium sp. and Ustilago maydis.
