Humans are capable of discovering and creating great things with the help of science and one such impressive discovery is that green, living plants can generate electricity. It may seem unbelievable, but not impossible.

One must be wondering how this technology works. Well, the answer is quite simple; photosynthesis. Plants excrete organic matter into the soil as a result of photosynthesis. Only some of the organic matter is used by plants and the rest is released in the soil. This released organic matter is broken down by bacteria. In the breakdown process, electrons are released as a waste product. Since the movement of electrons produces electricity, these electrons, which are of no use to the plant, can be harvested. The best part about this innovation is that the plants from which energy is being generated are not affected in any way.

This idea was first put into use by a Dutch start-up called Plant-e. This company was launched in September 2009 and is successful in launching and selling many environment- friendly products like DIY kits to the public for experimentation purposes and modular systems which could be easily installed on green roofs for abundant electricity production. Plant-e is involved in various projects, within The Netherlands, like automatic lighting systems in gardens and many more.

This technology works with the plants which thrive in moist soils and where the water is present in abundance. Therefore marshlands, paddy fields and deltas are some of the most suitable places for setting up plant batteries as a huge amount of water is present in those areas. Hence, the use of this technology is limited to certain geographic areas containing moist soils and cannot be used in arid regions. It may, however, promote the growth of more trees and plants which will gradually reverse the malicious effects of global warming.

Another obstacle in widespread adoption of this technology in today’s time is the high cost of installation of the system. The initial adopters of this technology are those who are attracted by the efficiency and eco-friendly nature of the plant batteries and willing to pay a premium for it.

The concept of plant batteries can be further taken into rural areas where most of the population still does not have access to adequate electricity. It is estimated that plant-MFC technology can cover upto 20% of European Union’s primary future electricity needs. Also, plants are almost 100% efficient at converting photons from sunlight into electrons which indicates a bright future for this technology. However, more research needs to be done in this field.

Another innovation in the field of green electricity is using algae , which often grows in ponds and rivers, for generating electricity. The basic concept which explains the working is similar to the way plants are able to produce electricity; photosynthesis.

Various other ventures in the field of renewable energy also include vegetable batteries, meaning, electric power generated from fruits and vegetables like lemons, tomatoes and potatoes, have been investigated. According to experiments, at least 3 to 4 vegetables are required just to light a small LED bulb. Moreover, it leads to poisoning of the vegetables and those food products need to be thrown away, without being useful for consumption purposes. It is therefore not a viable option for energy production.

Plant based electricity generation is still an evolving technology which has immense potential for producing energy in an environmentally sustainable way. It will realise full potential when the installation cost is attractive enough for the farmers to prefer it over the electricity grids or fossil fuel based personal electricity generator sets.

Does giving the Lieutenant Governor more authoritative power have an impact on India's Federal structure?

On 3rd of February 2021, the NCT bill cleared by cabinet along with 20 other bills proposed to be introduced in the parliamentary session. The amendment was passed on 9th of February in the Rajya Sabha.

“The Bill proposed to amend the Government of National Capital Territory of Delhi Act, 1991, in the context of judgment dated 14.02.2019 of Hon’ble Supreme Court (Division bench) in Civil Appeal No 2357 of 2017 and other connected matters.”

The article explains the timeline and the practical implications of the NCT Amendment Act 2021 on the federal structure.

The Centre's amendments to the NCT of Delhi Act, gives more powers to the Lieutenant Governor and Delhi’s Kejriwal government were totally against the amendment as due to their bitter experience with the previous and current LG.

The Arvind Kejriwal government described the NCT Bill, as a murder of constitutional democracy and accused BJP of secretively drafting the amendments so as to govern Delhi in an unconstitutional manner using the LG's office.

The new amendment is expected to now clearly define the powers and functions of the Lieutenant Governor and the Delhi Government based on the 2019 judgement. The amendments add a category of bills, which fall outside the ambit of Delhi legislative assembly and which the Lieutenant Governor must reserve for consideration of the President. This category is supposedly added for the sake of “better governance” and to reduce potential conflicts. The amendments also specify that the elected government needs to send legislative proposals to Lieutenant-Governor (LG) at least 14 days in advance to seek his opinion and avoid any delays.

The tussle between the Delhi government and the Centre reached the Supreme Court 2017. The honourable Supreme court defined the role of the LG in Delhi and ruled that the LG cannot interfere in every decision of the Delhi Government. The tussle between the Union and Delhi government has that Article 239 AA of the Constitution at its core. The Article 239 AA gives Delhi the special recognition of a Union Territory with a Legislative Assembly that has a lieutenant governor as its administrative head.

In July 2018, a five-judge Constitution bench of the Supreme Court led by Chief Justice Dipak Misra stated that the lieutenant governor’s powers in the National Capital were only limited to land, police and public order.

“The lieutenant governor must work harmoniously with the elected government. The LG is the administrative head but can’t act as an obstructionist”, the bench stated. The supreme court also stressed upon the fact that the power and status of the LG was different from the state governors. They mentioned that the Lieutenant Governor must not be an obstructionist and must work harmoniously with the Delhi government. “There is no room for absolutism and no room for anarchy,” the bench stated. The verdict is not complete yet as the issue of services divided the bench that delivered the order and the matter is now addressed by a three-judge bench on the Supreme Court which has not concluded the hearing yet.

So far, the AAP has argued that former LG Najeeb Jung and the current LG Anil Baijal are undermining the federal structure of the Republic of India by objecting the decisions made by the Delhi government and overruling their authority in bureaucratic matters.

In July 2013, Najeeb Jung took charge as the LG of Delhi and Arvind Kejriwal swore in as the Chief Minister (CM) of Delhi in December 2013. After 49 days of governance, Arvind Kejriwal stepped down as his minority government was unable to pass the anti-corruption legislation due to lack of support provided by other political parties. In February 2015, the Aam Aadmi Party came back to power by a staggering majority of 67 out of 70 seats. However, the party faced a higher veto obstruction while making several decisions. In May 2015, LG Jung annulled all the bureaucratic postings by Delhi government and stated that power to appoint and transfer rests with him.

In June 2015, five officers of Bihar Police joined Delhi Government’s Anti-Corruption Branch (ACB). Jung rejected their employment at the ACB claiming that he was the person in charge even before the new amendment. In the same month, the Delhi government replaced the Home Secretary Dharam Pal and Jung obstructed the decision by vetoing the order. When the AAP government decided to hike circle rates in Delhi for agricultural land, the former LG Jung objected to the decision although the State government has the complete authority to take such decisions. In another instance in 2016, Jung set up a panel to probe over 400 files related to decisions taken by Delhi government. The CM of Delhi deemed it to be illegal.

Kejriwal and the AAP government blamed the former LG and Prime Minister Narendra Modi for the CBI raids of his office, FIRs filed by ACB against Arvind Kejriwal and former Delhi CM Late Sheila Dikshit in water tanker scam, restriction of control on appointing state bureaucrats and general obstruction of decisions.

On 31st December 2016, Anil Baijal swore in as the Lieutenant Governor of Delhi. While the tussle between AAP and the LG continued, the alleged assault of Chief Secretary Anshu Prakash by AAP leaders at CM Arvind Kejriwal’s residence in February 2018 gave a new momentum to the tug of war.

Following the incident, the IAS association reportedly skipped routine meetings with ministers as a mark of protest but claimed that they have not suspended work. Before that, on December 2017, the turf war between Kejriwal and Baijal reached Parliament, with a Rajya Sabha member claiming that the CM was being treated like a “peon”.

In 2018, the AAP government demanded LG’s approval for the proposal for doorstep delivery of rations and also demanded grant of complete statehood for Delhi and installation of CCTVs. Baijal did not approve both the demands directly and further complicated the process. Kejriwal stated that the LG rejected the demands over “petty-politics”.

In June 2018, Delhi CM Arvind Kejriwal sat in a nine-day long hunger strike at the Lieutenant Governor’s office against the “strike” by IAS officers and Kejriwal wrote to Prime Minister Narendra Modi, requesting him, “with folded hands”, to intervene and end the agitation of the IAS officers.

The Aam Aadmi Party argues that the BJP is hell bent on ruining efficient governance of Delhi through the LG. Critics believe that the tussle has failed the federal system of our Democracy.

Chief Justice Dipak Misra, Justice Sikri and Justice Khanwilkar, in their written opinion devoted a significant portion to explain the understanding of federalism, and its fusion with democracy to achieve an “egalitarian social order”. According to our Constitutional scheme neither the States isolated islands, with their distinct vision, nor the Union government can make decisions that are meant to affect the interests of the States. The Chief Justice highlighted that there should be a sincere effort to avoid conflict and not encroach on each other spheres in a collaborative framework of federalism. To exercise authority, “there should be perception of mature statesmanship so that the constitutionally bestowed responsibilities are shared by them.” To attain the ideal balance in a federal structure, the Chief Justice suggested the Union and the States to have “mutual respect and deference to actualise the workability of a constitutional provision.”

Collaborative federalism involves healthy negotiation and coordination between the Union and State governments to ensure that the governance works within the circumference of the Constitution and in harmony.
